Comprehensive STD Screening in Texas

What this test measures

Sexually transmitted infections are common and often silent, which is why routine screening matters. Some infections produce no noticeable symptoms, especially in the early stages, and they can still be passed to partners. Screening helps identify infections so that a healthcare provider can discuss appropriate follow-up and prevention.

The panel combines sample types suited to each infection. Chlamydia and gonorrhea are usually detected from a urine sample or a swab using nucleic acid amplification. HIV and syphilis are detected from a blood sample using antigen, antibody, or treponemal tests. Some panels add hepatitis B, hepatitis C, herpes, or trichomonas testing depending on the order.

This testing is confidential and is not a diagnosis by itself. A negative result reflects the sample at the time it was collected, and timing after a possible exposure matters because each infection has a window period. A positive or unclear result should be reviewed promptly with a qualified healthcare provider, who can arrange confirmatory testing and discuss next steps.
