The STI Basic Panel covers the four most commonly screened sexually transmitted infections. It includes 4th-generation HIV testing (antigen + antibody), Chlamydia and Gonorrhea (urine-based RNA detection), and Syphilis screening. The CDC recommends STI screening for all sexually active adults, especially those with new partners or multiple partners.
3-test STI screen: HIV (4th-gen), Syphilis (with confirmation), Hepatitis C. The lowest-cost option for routine STI screening when partner-monitoring or post-exposure peace of mind is the goal.
Sexually active adults wanting routine screening, anyone with new partners, before a relationship status change. Add the [STI Comprehensive Panel](/tests/sti-comprehensive-panel) if you want chlamydia/gonorrhea and hepatitis B coverage.
