STI Test: can a DNA test help?

No, a typical consumer DNA test (like MyBody-X) cannot help with STI detection. These tests analyze your own genetic variants for traits like metabolism or ancestry, not the DNA of pathogens. STIs require specific diagnostic tests (e.g., PCR for chlamydia, gonorrhea, or HPV) performed on appropriate samples (urine, swab) in a clinical setting. A direct-to-consumer DNA test lacks the necessary pathogen-specific primers and validation. Relying on it for STI screening could lead to false reassurance. Always consult a healthcare provider for proper STI testing.
