Reactive

Also written as: Screen Reactive

Simple Meaning

A screening test (often for HIV or hepatitis) showed a signal and needs confirmation testing.

Where it appears in reports

On HIV, hepatitis, and other antibody screening reports.

Why it matters

Reactive is deliberately cautious language — screening tests are tuned to catch everything, so some reactives turn out negative on confirmation. No conclusions until confirmatory testing is done.

Doctor advice needed

Report words describe findings — they are not diagnoses. What "Reactive" means for you depends on your symptoms, history, and other results. Always review your report with your doctor.
