The GlutenID Celiac Genetic Health Risk Test uses qualitative genotyping to detect clinically relevant variants in genomic DNA isolated from salva collected from individuals 18 years of age or older with ORAcollect Dx OCD-100 for the purpose of reporting and interpreting Genetic Health Risks (GHR).
The GlutenID Celiac GHR Test is indicated for reporting of one variant associated with the HLA-DQ2.5 haplotype, one variant associated with the HLA-DQ8 haplotype, one variant associated with the HLA-DQ7 haplotype, and three variants associated with the HLA-DQ2.2 haplotype. The report describes if a person has variants linked to haplotypes associated with an increased risk for developing celiac disease, but it does not describe a person's overall risk of developing celiac disease. This report is most relevant for people of European descent.
Not Found
I apologize, but the provided text from the FDA 510(k) clearance letter for the "GlutenID Celiac Genetic Health Risk Test" does not contain the detailed information necessary to answer your request about acceptance criteria and the study proving the device meets them.
The letter is a formal notification of clearance, confirming that the device is substantially equivalent to legally marketed predicate devices. It discusses regulatory matters such as:
- The trade name and regulation details.
- General controls provisions and additional controls for Class II/III devices.
- Applicable regulations like Quality System (QS), Medical Device Reporting (MDR), and Unique Device Identification (UDI).
- Contact information for the FDA.
- The Indications for Use statement.
The document does NOT include information on:
- A table of acceptance criteria and reported device performance.
- Sample sizes for test sets, their provenance, or whether they were retrospective/prospective.
- Number of experts, their qualifications, or adjudication methods for ground truth.
- Whether a multi-reader multi-case (MRMC) comparative effectiveness study was performed or its effect size.
- Whether standalone (algorithm-only) performance was assessed.
- The type of ground truth used (e.g., expert consensus, pathology, outcomes data).
- Sample size for the training set or how its ground truth was established.
This kind of detailed study information is typically found in the 510(k) submission itself, often in a more extensive "Summary of Safety and Effectiveness" or a dedicated study report, which is not part of this specific FDA clearance letter.
Therefore, I cannot fulfill your request based solely on the provided text.
§ 866.5950 Genetic health risk assessment system.
(a)
Identification. A genetic health risk assessment system is a qualitative in vitro molecular diagnostic system used for detecting variants in genomic deoxyribonucleic acid (DNA) isolated from human specimens that will provide information to users about their genetic risk of developing a disease to inform lifestyle choices and/or conversations with a health care professional. This assessment system is for over-the-counter use. This device does not determine the person's overall risk of developing a disease.(b)
Classification. Class II (special controls). The genetic health risk assessment system device, when it has previously received a first-time FDA marketing authorization (e.g., 510(k) clearance) for the genetic health risk assessment system (a “one-time FDA reviewed genetic health risk assessment system”), is exempt from the premarket notification procedures in part 807, subpart E, of this chapter subject to the limitations in § 866.9. The device must comply with the following special controls:(1) The 21 CFR 809.10 compliant labeling and any prepurchase page and test report generated, unless otherwise specified, must include:
(i) A section addressed to users with the following information:
(A) The limiting statement explaining that this test provides genetic risk information based on assessment of specific genetic variants but does not report on a user's entire genetic profile. This test [does not/may not, as appropriate] detect all genetic variants related to a given disease, and the absence of a variant tested does not rule out the presence of other genetic variants that may be related to the disease.
(B) The limiting statement explaining that other companies offering a genetic risk test may be detecting different genetic variants for the same disease, so the user may get different results using a test from a different company.
(C) The limiting statement explaining that other factors such as environmental and lifestyle risk factors may affect the risk of developing a given disease.
(D) The limiting statement explaining that some people may feel anxious about getting genetic test health results. This is normal. If the potential user feels very anxious, such user should speak to his or her doctor or other health care professional prior to collection of a sample for testing. This test is not a substitute for visits to a doctor or other health care professional. Users should consult with their doctor or other health care professional if they have any questions or concerns about the results of their test or their current state of health.
(E) Information about how to obtain access to a genetic counselor, board-certified clinical molecular geneticist, or equivalent health care professional about the results of a user's test.
(F) The limiting statement explaining that this test is not intended to diagnose a disease, tell you anything about your current state of health, or be used to make medical decisions, including whether or not you should take a medication or how much of a medication you should take.
(G) A limiting statement explaining that the laboratory may not be able to process a sample, and a description of the next steps to be taken by the manufacturer and/or the customer, as applicable.
(ii) A section in your 21 CFR 809.10 labeling and any test report generated that is for health care professionals who may receive the test results from their patients with the following information:
(A) The limiting statement explaining that this test is not intended to diagnose a disease, determine medical treatment, or tell the user anything about their current state of health.
(B) The limiting statement explaining that this test is intended to provide users with their genetic information to inform lifestyle decisions and conversations with their doctor or other health care professional.
(C) The limiting statement explaining that any diagnostic or treatment decisions should be based on testing and/or other information that you determine to be appropriate for your patient.
(2) The genetic test must use a sample collection device that is FDA-cleared, -approved, or -classified as 510(k) exempt, with an indication for in vitro diagnostic use in over-the-counter DNA testing.

Performance criteria for both the comparator method and the device must be predefined and appropriate to the device's intended use. Detailed study protocols must be provided.(
iii ) Test specimens must include all genotypes that will be included in the tests and reports. The number of samples tested in the accuracy study for each variant reported must be based on the variant frequency using either the minimum numbers of samples identified in this paragraph or, when determined appropriate and identified by FDA, a minimum number of samples determined using an alternative method. When appropriate, the same samples may be used in testing to demonstrate the accuracy of testing for multiple genotypes by generating sequence information at multiple relevant genetic locations. At least 20 unique samples representing the wild-type genotype must be tested. To test samples that are heterozygous for the reported variant(s), common variants (>0.1 percent variant frequency in the relevant population) must be tested with at least 20 unique samples. Rare variants (≤0.1 percent variant frequency in the relevant population) must be tested with at least three unique samples. To test samples that are homozygous for the reported variant(s), variants with ≥2 percent variant frequency in a relevant population must be tested with at least 20 unique samples. Variants with a frequency in the relevant population
