determination of HBsAg in serum. Monoclonal and polyclonal antibodies were
employed to specifically identify HBsAg with high sensitivity. This one step test only
takes about 10-20 minutes. The sensitivity of the test can reach to 5ng/ml.
Specimen collection
For serum, collect blood into container without anticoagulant. Allow the blood to clot
and separate the serum from the clot. Use the serum for testing.
If the specimen cannot be tested on the day of collection, store the serum specimen in
a refrigerator or freezer. Bring the specimens to normal room temperature before
testing. Do not freeze or thaw the specimen repeatedly.

apparent band on the test region.

band will also appear in the test region.
