Genetic analysis evaluating variations within the methylenetetrahydrofolate reductase (MTHFR) gene can now be performed using sample collection kits intended for use in a residential setting. These kits typically involve collecting a saliva sample or a buccal swab, which is then mailed to a laboratory for processing and interpretation of results.
Identifying certain MTHFR gene variants may be relevant to understanding an individual’s predisposition to specific health conditions or their response to particular medications. Historically, genetic testing required a visit to a healthcare provider; however, the accessibility of at-home collection methods provides individuals with greater convenience and potentially reduces barriers to genetic information.
