ABAcard P30 (HemaTrace P30)
Definition
A lateral-flow immunochromatographic card that detects PSA at approximately 0.2-4 ng/mL of extract. Widely used in sexual assault kit triage because it requires no instruments and gives a visible result in 10 minutes.
- Target
- PSA (prostate-specific antigen)
- Sensitivity
- ~0.2-4 ng/mL of extract
- Format
- Lateral-flow immunochromatographic card
- Result time
- About 10 minutes
Common questions
What does a positive p30 result actually indicate?+
It indicates the presence of prostate-specific antigen, a marker associated with seminal fluid, which is why the test is used to triage evidence in sexual assault cases before committing samples to further testing.
Does running this test require lab instrumentation?+
No. It is a visually read strip test that gives a result in about 10 minutes without instruments, which is exactly why it is used for rapid triage of sexual assault kit items.
