Direct Answer
This rapid test detects Hepatitis B surface antigen in WB / S / P to support Hepatitis B. It is a colloidal-gold screening test — a reactive result is presumptive and should be confirmed per the intended use.
Intended Use
Detection of Hepatitis B surface antigen (HBsAg) for HBV infection screening.
Clinical Context
HBsAg is the earliest viral antigen marker of acute HBV and a marker of chronic infection. Widely used in blood-bank and antenatal screening.
Test Principle
Colloidal-gold immunochromatography (lateral flow). The device captures the target analyte (antigen or antibody) on a membrane via labeled antibodies, producing a visible test line within minutes. Qualitative or semi-quantitative, intended as a screening/triage aid — not a replacement for confirmatory laboratory testing.
Limitations
Reactive results require confirmatory testing (neutralization / HBV DNA); does not distinguish acute from chronic.
Procurement
Specimen: whole blood / serum / plasma. Format: cassette / strip. Registration in progress.
Interpretation
| Result | Lines | Meaning |
|---|---|---|
| Positive | Test + control line | Target detected (presumptive positive) |
| Negative | Control line only | Below cut-off / not detected |
| Invalid | No control line | Repeat with a new device |
Common misconception
A negative rapid test does not always exclude infection — timing, specimen and pathogen load all matter. Follow up clinically where suspicion is high.
Sources
Screening results are presumptive, not diagnostic. Confirmatory testing follows WHO, CDC and national regulatory guidance — see screening vs confirmatory.
