No
The description focuses on standard genotyping methods and software for data processing and report generation, with no mention of AI or ML techniques.
No.
The device is a qualitative genotyping service used to detect genetic variants and report health risks, not to treat or prevent a disease or condition.
Yes
Explanation: The device uses qualitative genotyping to detect genetic variants and provides a report describing if a person is at increased risk of developing lung and/or liver disease linked to AATD. This falls under the definition of a diagnostic device as it uses testing to identify potential health risks.
No
The device description explicitly states that the service is composed of a saliva collection kit (hardware), a genotyping test (hardware/reagents), and software. While software is a component, it is not the sole component of the medical device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the service "uses qualitative genotyping to detect clinically relevant genetic variants associated with alpha-1 antitrypsin deficiency (AATD) in genomic DNA isolated from human saliva... for the purpose of reporting and interpreting Genetic Health Risks (GHR)." This involves testing a sample taken from the human body to provide information about a health condition.
- Device Description: The description details the components of the service, including a saliva collection kit, a genotyping test for genetic analysis, and software to provide results. The genotyping test specifically analyzes human DNA from the saliva sample to detect genetic variants.
- Performance Studies: The document describes analytical performance studies (reproducibility/precision and method comparison) and clinical performance (risk categorization based on published clinical cases). These types of studies are characteristic of IVD devices to demonstrate their accuracy and reliability in providing diagnostic information.
- Predicate Device: The predicate device listed is the "23andMe Personal Genome Service (PGS) Genetic Health Risk Test (Alpha-1 Antitrypsin Deficiency)" (DEN160026). This is a known IVD device for genetic health risk testing.
The definition of an IVD device generally includes reagents, instruments, and systems intended for use in the diagnosis of disease or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae. This service fits this definition by analyzing a human sample (saliva) to provide information about a genetic condition (AATD) and associated health risks (lung and liver disease).

Intended Use / Indications for Use
The AlphaID™ At Home Genetic Health Risk Service uses qualitative genotyping to detect clinically relevant genetic variants associated with alpha-1 antitrypsin deficiency (AATD) in genomic DNA isolated from human saliva collected from individuals ≥ 18 years with ORAcollect Dx OCD-100.014 for the purpose of reporting and interpreting Genetic Health Risks (GHR).
This Service is indicated for reporting 14 genetic variants in the SERPINA1 gene: PIS; PIM procida; PIM malton; PIS iyama; PIQ0 granite falls; PIQ0 west; PIQ0 bellingham; PIF; PIQ0 mattawa; PIQ0 clayton, and PI*M heerlen. The report describes if a person is at an increased risk of developing either liver disease linked to AATD. The report does not describe a person's overall risk of developing lung and/or liver disease. AATD is more common in persons of European descent.
Special conditions for use statements:
a. For over-the-counter (OTC) use.
b. The test is intended for users ≥18 years old.
c. The test is not a substitute for an appointment with a healthcare professional. It is recommended that the user consults with a healthcare professional if the user has any questions or concerns about his/her results.

Device Description
The AlphaID™ At Home Genetic Health Risk Service (AlphaID At Home) uses qualitative genotyping to detect clinically relevant genetic variants associated with alphal-antitrypsin deficiency (AATD) and provides a report describing if a person is at risk of developing either lung and/or liver disease linked to AATD. This Service is direct-to-consumer and intended for an Over-the Counter (OTC) use.
The AlphaID™ At Home Genetic Health Risk Service is composed by AlphaID™ At Home Saliva Collection kit for human saliva sample collection (ORAcollect®·Dx OCD-100.014), A1AT Genotyping Test for the genetic analysis and detection of genetic variants associated with alpha-1 antitrypsin deficiency (AATD), and AlphaID™ At Home Genetic Health Risk Service website and result portal software to provide the contents and the procedure to order and use the over the counter (OTC) Service.
A consumer's saliva is self-collected using custom version ORAcollect Dx (model OCD-100.014) device manufactured by DNA Genotek, Inc (See K212745) which consists of collection tube containing a stabilizing buffer solution. Once the sample is collected, it is shipped to Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory for processing.
Human DNA from the saliva sample is isolated and processed with the A1AT Genotyping Test device (K211115) that provides results on 14 genetic variants in the SERPINA / gene: PIS; PIZ; PIM procida; PIM malton; PIS iiyama; PIO0 granite falls: PIO0 west: PIO0 bellingham: PIF; PIP lowell; PIO0 mattawa; PIQ0 clayton, and PI*M heerlen.
Briefly, genomic DNA extracted from human saliva is amplified and biotinylated by multiplex PCR and PCR products are denatured and hybridized to oligonucleotide probes coupled to color-coded beads. Hybridized DNA is labeled with a fluorescent conjugate and the resulting signal is detected with a Luminex® 200™ system. Raw fluorescence data is processed with the A1AT Genotyping Test ANALYSIS SOFTWARE to provide allelic variant genotypes, which are subsequently converted into associated alleles, based on current scientific evidence. Additionally, the software application also provides the type of Genetic Health Risk Report associated with the identified alleles, which is subsequently used as the basis for the generation of personalized reports by the AlphaID™ At Home Genetic Health Risk Service website and result portal.
Depending on the specific variant combination detected, the AlphaID™ At Home Genetic Health Risk Service provides the individuals' genetic health risk for developing lung and liver disease linked to AATD. Personalized reports, in an easy-to-understand format are generated for each consumer that provide results of the testing performed.

Analytical Performance
a. Reproducibility/Precision
CLIA-Certified Laboratory Verification Study: A total of 110 samples collected with AlphaID™ At Home Saliva Collection kit in an over the counter (OTC) environment were processed with the A1AT Genotyping Test at Progenika following the Package Insert and afterwards at Matrix Clinical Clinical Labs following the internal Standard Operational Procedure (SOP) that will be used afterwards during routine testing of the AlphaIDTM At Home Genetic Health Risk Service. The acceptance criteria for the study were fulfilled (concordance ≥99% and "Invalid Tests" ≤2%). The concordance between A1AT Genotyping Test results obtained in Matrix Clinical Labs and Progenika was 100% per reported variant and overall, among all tested samples. No "Invalid Tests" results were observed at Matrix Clinical Labs.
2. Comparison Studies
a. Method Comparison with the Predicate
A method comparison study was performed to assess the accuracy of A1AT Genotyping Test to correctly detect the genetic variants. A total of 227 samples representing all genetic variants interrogated by the assay were analyzed and compared with Bi-Directional-Sequencing (BDS) (reference method). Percent Agreement (PA) between the two methods for the overall variants and samples (14 variants and 227 samples) was 100% (227/227) with a 95% confidence interval 98.3% to 100%. The percentage of overall "Invalid Tests" was 0% (0/227) with 95% confidence interval 0% to 1.7%.
3. Clinical Studies
a. Clinical Performance
The AlphaID™ At Home Genetic Health Risk Service has been developed for the detection of 14 variants in the SERPINA1 gene associated with alphalantitrypsin deficiency (AATD), including the most common ones. Depending on the specific variant combination detected, the AlphaID™ At Home Genetic Health Risk Service provides the individuals' genetic health risk for developing lung and liver disease linked to alphal-antitrypsin deficiency (AATD).The risk categorization is based on the reported clinical cases (published references) for each genetic result.
The AlphaID™ At Home Genetic Health Risk Service uses four (4) categories to define risk:
- Increased risk: There is an increased risk of developing lung or liver disease linked to AATD compared to the general population*. The chance of developing lung or liver disease linked to AATD is higher than that of the general population. Above 80% of people with this genetic result develop lung or liver disease during their lifetime.
- Slightly at Increased risk: There is a slightly increased risk of developing lung or liver disease linked to AATD compared to the general population*. The chance of developing lung or liver disease linked to AATD is slightly higher than that of the general population. 20-80% of people with this genetic result develop lung or liver disease during their lifetime.
- Not likely at increased risk: There is average risk of developing lung or liver disease linked to AATD compared to the general population*. The chance of developing lung or liver disease linked to AATD is similar to that of the general population. Below 20% of people with this genetic result develop lung or liver disease during their lifetime.
- Unknown risk: The risk of developing lung or liver disease linked to AATD is not known due to the lack of reported clinical cases or inconclusive data. The chance of developing lung or liver disease linked to AATD is unknown. More clinical studies are needed to determine the risk level.
b. User Comprehension Studies
AlphaID™ At Home Genetic Health Risk Service report user comprehension study: The user comprehension study for the AlphaID™ At Home Genetic Health Risk Service showed that a demographically diverse US population of naïve users (525 participants) of the Service reports had excellent comprehension of the service's purpose, limitations, results, relevance of ethnicity, other factors that may impact test results, and appropriate next steps. Comprehension was tested through a two-step process. First, participants' comprehension was tested prior to viewing the educational module and Service reports. Second, participants were shown the educational module and the Service reports. Participants completed a survey after the first and second step. As a result, each comprehension domain achieved a minimum of 90.1% or higher user comprehension score in the first step, and 94.0% or higher user comprehension score in the second step, across all reports. The overall comprehension scores were of 92.7% and 96.8% across all comprehension domains and reports, for the first and second step respectively.

J. DEVICE DESCRIPTION
The AlphaID™ At Home Genetic Health Risk Service (AlphaID At Home) uses qualitative genotyping to detect clinically relevant genetic variants associated with alphal-antitrypsin deficiency (AATD) and provides a report describing if a person is at risk of developing either lung and/or liver disease linked to AATD. This Service is direct-to-consumer and intended for an Over-the Counter (OTC) use.
The AlphaID™ At Home Genetic Health Risk Service is composed by AlphaID™ At Home Saliva Collection kit for human saliva sample collection (ORAcollect®·Dx OCD-100.014), A1AT Genotyping Test for the genetic analysis and detection of genetic variants associated with alpha-1 antitrypsin deficiency (AATD), and AlphaID™ At Home Genetic Health Risk Service website and result portal software to provide the contents and the procedure to order and use the over the counter (OTC) Service.
A consumer's saliva is self-collected using custom version ORAcollect Dx (model OCD-100.014) device manufactured by DNA Genotek, Inc (See K212745) which consists of collection tube containing a stabilizing buffer solution. Once the sample is collected, it is shipped to Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory for processing.
Human DNA from the saliva sample is isolated and processed with the A1AT Genotyping Test device (K211115) that provides results on 14 genetic variants in the SERPINA / gene: PIS; PIZ; PIM procida; PIM malton; PIS iiyama; PIO0 granite falls: PIO0 west: PIO0 bellingham: PIF; PIP lowell; PIO0 mattawa; PIQ0 clayton, and PI*M heerlen.
Briefly, genomic DNA extracted from human saliva is amplified and biotinylated by multiplex PCR and PCR products are denatured and hybridized to oligonucleotide probes coupled to color-coded beads. Hybridized DNA is labeled with a fluorescent conjugate and the resulting signal is detected with a Luminex® 200™ system. Raw fluorescence data is processed with the A1AT Genotyping Test ANALYSIS SOFTWARE to provide allelic variant genotypes, which are subsequently converted into associated alleles, based on current scientific evidence. Additionally, the software application also provides the type of Genetic Health Risk Report associated with the identified alleles, which is subsequently used as the basis for the generation of personalized reports by the AlphaID™ At Home Genetic Health Risk Service website and result portal.

L. TEST PRINCIPLE
The AlphaID™ At Home Genetic Health Risk Service is performed by CLIAcertified laboratory using Alpha-1 antitrypsin (A1AT) Genotyping Test (K211115). A1AT Genotyping Test utilizes Luminex xMAP technology. Genomic DNA is extracted from from human saliva samples collected as buccal swabs using ORAcollect:Dx OCD-100.014. Extracted DNA is amplified and biotinylated by multiplex PCR and PCR products are denatured and hybridized to oligonucleotide probes coupled to color-coded beads. Hybridized DNA is labeled with a fluorescent conjugate and the resulting signal is detected with a Luminex® 200 system (with xPONENT® software). Raw data obtained is processed with the A1AT Genotyping Test ANALYSIS SOFTWARE. The A1AT Genotyping Test ANALYSIS SOFTWARE algorithm converts the allelic variant genotypes into associated alleles, based on the current literature. Additionally, this software application also provides an associated template number for each sample, this is, a code that defines the type of Genetic Health Risk Report that will be generated for each individual, depending on its combination of variants or Sample Result. This template number will be subsequently used as the basis for the generation of personalized reports by the AlphaID™ System.

A total of 227 samples representing all genetic variants interrogated by the assay were analyzed and compared with Bi-Directional-Sequencing (BDS) (reference method). Percent Agreement (PA) between the two methods for the overall variants and samples (14 variants and 227 samples) was 100% (227/227) with a 95% confidence interval 98.3% to 100%. The percentage of overall "Invalid Tests" was 0% (0/227) with 95% confidence interval 0% to 1.7%.
3. Clinical Studies
a. Clinical Performance
The AlphaID™ At Home Genetic Health Risk Service has been developed for the detection of 14 variants in the SERPINA1 gene associated with alphalantitrypsin deficiency (AATD), including the most common ones. Depending on the specific variant combination detected, the AlphaID™ At Home Genetic Health Risk Service provides the individuals' genetic health risk for developing lung and liver disease linked to alphal-antitrypsin deficiency (AATD).The risk categorization is based on the reported clinical cases (published references) for each genetic result.
The AlphaID™ At Home Genetic Health Risk Service uses four (4) categories to define risk:
- Increased risk: There is an increased risk of developing lung or liver disease linked to AATD compared to the general population*. The chance of developing lung or liver disease linked to AATD is higher than that of the
18
general population. Above 80% of people with this genetic result develop lung or liver disease during their lifetime.
-
Slightly at Increased risk: There is a slightly increased risk of developing lung or liver disease linked to AATD compared to the general population*. The chance of developing lung or liver disease linked to AATD is slightly higher than that of the general population. 20-80% of people with this genetic result develop lung or liver disease during their lifetime.
-
Not likely at increased risk: There is average risk of developing lung or liver disease linked to AATD compared to the general population*. The chance of developing lung or liver disease linked to AATD is similar to that of the general population. Below 20% of people with this genetic result develop lung or liver disease during their lifetime.
-
Unknown risk: The risk of developing lung or liver disease linked to AATD is not known due to the lack of reported clinical cases or inconclusive data. The chance of developing lung or liver disease linked to AATD is unknown. More clinical studies are needed to determine the risk level.
*General population is defined as all adults who reside in the United States.
When "No Variants" are detected by the Service, the result will show "Not Likely at Risk for AATD".
b. User Comprehension Studies
AlphaID™ At Home Genetic Health Risk Service report user comprehension study:
The user comprehension study for the AlphaID™ At Home Genetic Health Risk Service showed that a demographically diverse US population of naïve users (525 participants) of the Service reports had excellent comprehension of the service's purpose, limitations, results, relevance of ethnicity, other factors that may impact test results, and appropriate next steps. Comprehension was tested through a two-step process. First, participants' comprehension was tested prior to viewing the educational module and Service reports. Second, participants were shown the educational module and the Service reports. Participants completed a survey after the first and second step. As a result, each comprehension domain achieved a minimum of 90.1% or higher user comprehension score in the first step, and 94.0% or higher user comprehension score in the second step, across all reports. The overall comprehension scores were of 92.7% and 96.8% across all comprehension domains and reports, for the first and second step respectively.

3. Specimen Identification
Consumers must register their saliva collection kit, linking their saliva sample to a secure online account through a unique barcode, in order to access to their results report. The unique barcode is matched to records card of kits shipped to consumers to ensure it is a valid kit. A timestamp of the consumer completing the entries to register the kit is recorded. The saliva sample is processed and result reported by the laboratory using a traceable kit barcode.
4. Specimen Sampling and Handling
Saliva samples should be collected using the AlphaID™ At Home Saliva Collection kit (ORAcollect·Dx OCD-100.014 from DNA Genotek) collection kit.
Using the provided instructions for use, the consumer uses the integrated sponge on the device to collect a saliva sample from the mouth. After saliva is collected, the cap is removed from the tube, inverted to place the sponge into the collection tube with the stabilizing liquid, and re-capped with the sponge remaining inside the tube. Upon contacting saliva cells, the stabilizing liquid lyses cellular and nuclear membranes to release and stabilize nucleic acids (DNA). Samples can be immediately processed, transported or stored for future use. Device and sample integrity are preserved during typical ambient transport and storage conditions.
