Short answer
STI results come in three flavors, each triggering different next steps: positive (infection found, treat promptly, inform partners, retest on schedule); negative (not detected under the test’s conditions, qualified by windows, sites, and coverage, with retests where qualifiers fail); indeterminate or reactive-screen (confirmation pending. Avoid sex and conclusions until resolved).
Each is actionable information, never a verdict. And positives are the commonest path into treatment that resolves them.

See Tests & Prices →Positive results. Treatment plus network care
- Begin prescribed treatment exactly as directed (full adherence. Partial courses breed resistance and recurrence).
- Abstain as directed (through completion plus symptom resolution for patient and partners).
- Ensure partners are evaluated and treated (look-back windows per infection. Provider referral or EPT where direct routes fail).
- Attend follow-up and retesting (test-of-cure where indicated, reinfection surveillance universally).
- Ask about prevention layering (vaccines, PrEP, condoms, screening rhythms. The episode’s lessons formalized).
A positive result is medical information to act on. Stigma helps nothing, speed helps everything.

Negative results. Qualified clearance, not immunity
- Confirm what the negative covers: which infections (panel contents versus exposures), which sites (genital plus throat/rectal where relevant), and whether window periods had closed (exposure-dated intervals per test type).
- Persistent symptoms after negatives need re-evaluation. Wrong-site sampling, pre-window timing, uncovered organisms (M. genitalium, trichomoniasis where untested), non-STI causes. Not repeated identical tests forever.
- Negatives describe the past, never the future (no immunity conferred. Ongoing risk patterns keep condoms, screening, and communication in place).
Negative-specific guidance: Understanding a Negative STI Test Result.
Indeterminate and reactive results. The pending category
- Common with syphilis and herpes serology and early HIV testing (screening-reactive lines awaiting confirmatory cascades).
- Laboratories reflex to confirmatory tests automatically in most systems (differentiation assays, tiebreakers, RNA where indicated. Staged results over days).
- Clinicians explain final interpretations (screening lines are questions, confirmatory lines are answers. Read every line before concluding).
- Avoid sex and avoid conclusions until resolved (precaution without verdict. Abstinence bridging plus documented testing sequence).
Logistics worth confirming. Closed-loop results
- How results arrive (portal, call, text. Confirmed at the visit, not assumed).
- Typical turnaround (rapids minutes, NAAT days, confirmations longer. With buffer expectations).
- Who explains them (ordering clinician, results line, portal messaging. Named contacts, not general numbers).
- What happens if notification is missed (call-back protocols. Never assume silence is clearance).
- Update contact details so results reach you (result-safe channels stated explicitly at every visit).

Immediately for positive results needing treatment, for symptoms despite negatives, to resolve indeterminate results, and for scheduled retesting after treatment.
