No
The device description mentions a "standard melting curve analysis software algorithm" which is a deterministic method, not AI/ML. There is no mention of AI, ML, or related terms in the document.
No.
This device is an in vitro diagnostic test used to identify genetic variations in patients that may put them at risk of warfarin sensitivity. It provides information to aid in diagnosis, not to treat or prevent a disease.
Yes
The "Intended Use / Indications for Use" section explicitly states that "The eQ-PCR™ LC Warfarin Genotyping kit is an in vitro diagnostic test." It also indicates its use "as an aid in identifying patients who may be at risk of warfarin sensitivity," which is a diagnostic purpose.
No
The device is an in vitro diagnostic test kit that includes reagents and is used with a specific hardware instrument (Roche Diagnostics LightCycler® Real-Time PCR System instrument model 1.2). While it uses software for analysis, it is not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The document explicitly states that the eQ-PCR™ LC Warfarin Genotyping kit is an "in vitro diagnostic test" and is "for use in clinical laboratories upon prescription by the attending physician." It also states its intended use as an "aid in identifying patients who may be at risk of warfarin sensitivity." These phrases are clear indicators of an IVD.
- Device Description: The description details a test performed on "human peripheral blood samples" using a kit containing reagents (primers and probes) and an instrument (Roche Diagnostics LightCycler® Real-Time PCR System). This process of analyzing biological samples outside the body is characteristic of an in vitro diagnostic.
- Anatomical Site: The test is performed on "human peripheral blood samples," which are biological specimens collected from the body for analysis in vitro.
- Intended User/Care Setting: The test is intended for use in "clinical laboratories upon prescription by the attending physician," which is a typical setting for IVD testing.
- Performance Studies: The document describes clinical performance studies comparing the device to a reference method (bi-directional sequencing) using human samples, which is a requirement for demonstrating the performance of an IVD.
- Predicate Device(s): The mention of a predicate device (K070804; Verigene® Warfarin Metabolism Nucleic Acid Test) further confirms that this device is being submitted as an IVD, as predicate devices are used in the regulatory submission process for new IVDs.
All of these factors strongly indicate that the eQ-PCR™ LC Warfarin Genotyping kit is an In Vitro Diagnostic device.

Device Description
The eQ-PCR 1M LC Warfarin Genotyping Kit assay requires extracted DNA obtained by using any commercially available DNA extraction kit. The extracted DNA sample, within a range of 50-200ng of total DNA, is mixed with a PCR Mix, and an eQ-PCR "M specific Probe Mix reagent containing specific primers and fluorescent labeled probes for the CYP2C9 and/or VKORC1 gene polymorphisms. Amplification and detection are then performed in the Roche Diagnostics LightCycler® Real-Time PCR System instrument model 1.2 using conditions defined in the specific eQ-PCRTM LC Warfarin Genotyping Kit Product Insert. After the PCR reaction is completed, the Roche Diagnostics LightCycler® Real-Time PCR System instrument automatically proceeds to the melting curve-based detection method. This real time PCR test is a closed test system and does not require post PCR operations. It reduces human errors and eliminates post-PCR handling contamination.

Description of the test set, sample size, data source, and annotation protocol
A clinical trial was conducted to test the performance of the eQ-PCRTM LC Warfarin Genotyping Kit compared to bi-directional sequencing using extracted nucleic acid from whole blood from 159 donors. Two EDTA-anticoagulated whole blood samples were collected from each of 159 adult volunteers. The samples were collected under IRB approval and with Informed Consent. The whole blood samples were extracted at a reference laboratory. The extracted DNA from the two samples from the same matrix per donor was pooled for testing in the study. Bi-directional sequencing was performed at a reference laboratory on the 159 DNA samples extracted from the whole blood samples.
Aliquots of the extracted nucleic acid samples were prepared at TrimGen at a concentration of 10ng/uL. Each testing site received aliquots of 50 whole blood (WB) DNA. and 9 commercial control DNA samples. The donor samples tested at each site were unique to that site and did not duplicate the donors at the other two sites. Ten (10) WB samples were tested with the eQ-PCR 104 LC Warfarin Genotyping Kit and the Roche LightCycler each day for a total of 5 testing days.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical Performance: A clinical trial was conducted to test the performance of the eQ-PCRTM LC Warfarin Genotyping Kit compared to bi-directional sequencing using extracted nucleic acid from whole blood from 159 donors. The clinical sensitivity results are summarized in a table:
- CYP2C9*2 Wild Type: 123/126 (97.6%)
- CYP2C9*2 Heterozygous: 27/28 (96.4%)
- CYP2C9*2 Variant: 5/5 (100%)
- CYP2C9*3 Wild Type: 138/140 (98.6%)
- CYP2C9*3 Heterozygous: 12/13 (92.3%)
- CYP2C9*3 Variant: 5/6 (83.3%)
- VKORC1 Wild Type: 77/79 (97.5%)
- VKORC1 Heterozygous: 62/63 (98.4%)
- VKORC1 Variant: 17/17 (100%)
The initial results showed overall 99.6% clinical sensitivity of the eQ-PCR ™ LC Warfarin Genotyping Kit compared to bi-directional results for the whole blood samples. Only 0.4% (2/450) of the results was discordant and resolved in agreement with the eQ-PCRTM LC Warfarin Genotyping Kit result when bidirectional sequencing was repeated. After re-sequencing the discrepant samples, the overall result demonstrates 100% clinical sensitivity of the assay's substantial equivalence to bi-directional sequencing.
Reproducibility: A study was conducted at two external sites and at TrimGen Corporation to determine the reproducibility of the eQ-PCR™ LC Warfarin Genotyping Kit across days, operators, and sites. A panel of 31 samples was extracted and tested at each of the three sites on each of five days. The panel consisted of whole blood samples. There was no discordance among observed results or between observed and expected results across sites, days or operators. All whole blood and controls gave consistent eQ-PCR™ LC Warfarin Genotyping Kit results within days, across days, across operators, and across sites. In addition, all genotyping results matched the bi-directional sequencing results.
