Introduction to HBsAg Test Cassette
The HBsAg test cassette is a diagnostic tool used for the detection of the Hepatitis B surface antigen (HBsAg) in human serum, plasma, or whole blood. It is widely used in medical settings, especially for screening blood donors and monitoring the population for Hepatitis B infection. The presence of HBsAg indicates active Hepatitis B virus (HBV) infection.
Application of the HBsAg Test Cassette
The primary application of the HBsAg test cassette is in clinical diagnostics for Hepatitis B infection. It serves various purposes including:
- Screening blood donations to prevent HBV transmission via transfusion.
- Early detection of HBV infection in at-risk populations.
- Monitoring patients with chronic HBV infection.
The test cassette operates on an immunochromatographic assay. It usually delivers results within 15-20 minutes with high specificity and sensitivity, typically above 98% for both parameters.

Numerical Analysis of Test Efficacy
In a comparative study of various HBsAg test cassettes, the following metrics were recorded for efficacy:
- Sensitivity: 98.8% across a sample size of 1,200 individuals.
- Specificity: 99.1% across a sample size of 1,200 individuals.
- Positive Predictive Value (PPV): 97.5%.
- Negative Predictive Value (NPV): 99.5%.
These figures illustrate the high reliability of the HBsAg test cassette in clinical practice.
