What the authorization says it may report
23andMe Personal Genome Service pharmacogenetic reports for CYP2C19 describes if a person has variants associated with metabolism of some therapeutics and provides interpretive drug information regarding the potential effect of the identified metabolizer phenotype on citalopram and clopidogrel therapy.
The information provided by this report should not be used to start, stop, or change any course of treatment.
Stated limitations
This report does not determine if a person will or will not respond to a particular therapeutic.
This test does not provide interpretive drug information for the CYP2C19 *3/*17 heterozygous genotype.
Do not use your results to start, stop or change any course of treatment.
FDA classifies this test type under 21 CFR 862.3364, which says: “A pharmacogenetic assessment system is a qualitative in vitro molecular diagnostic system intended to detect nucleic acid variants isolated from human specimens for the purpose of assessing the presence of genetic variants that impact the metabolism, exposure, response, risk of adverse events, dosing, or mechanisms of prescription or over-the-counter medications.” (21 CFR 862.3364)
Also in the FDA file
to add one new indication describing interpretive drug information to two specific medications (citalopram and clopidogrel), as well as to remove the limitation language requiring confirmatory testing.
What this record doesn't tell you
An FDA record says what a test was authorized to report on the decision date. It doesn't say whether the product is still sold, what it costs, or which version a kit in a store uses. Check the company's own label and report for the current claims.
FDA's general advice on direct-to-consumer tests: “Do not make any dietary or health-related decisions without first discussing your test results with your health care provider.” (U.S. Food and Drug Administration)
