The One Step HBsAg Test is a rapid chromatographic immunoassay for the qualitative detection of Hepatitis B surface Antigen (HBsAg) in Whole Blood /Serum / Plasma.
The One Step HBsAg Test is a qualitative membrane strip based immunoassay for the detection of Hepatitis B surface Antigen in Whole Blood /Serum / Plasma. In this test procedure, HBsAg antibody is immobilized in the test line region of thedevice. After a Whole Blood /Serum / Plasma specimen is placed in the specimen well, it reacts
with HBsAg antibody coated particles that have been applied to the specimen pad. This mixture migrates chromatographically along the length of the test strip and interacts with the immobilized HBsAg antibody. If the specimen contains Hepatitis B surface Antigen, a colored line reg the line will appear indicating a positive result. If the specimen does not containHepatitis B surface Antigen, a colored line will not appear in this region indicating a negative result. To serve as a procedural control, a colored line will always appear at the control line region indicating that proper The volume of specimen has been added and membrane wicking has occurred.
Materials and Components
2. Disposable specimen droppers
3. Buffer (for whole blood only)
|Whole Blood /Serum /Plasma
|4-30℃ or 40-86℉
Allow the test, specimen, buffer and/or controls to reach room temperature 15-30℃(59-86℉) prior to testing.
Place the test device on a clean and level surface.
(1) For serum or plasma specimen: Hold the dropper vertically and transfer 3 drops of serum or plasma (approximately 100μl) to the specimen well(S) of the test device, then start the timer.
(2) For whole blood specimens: Hold the dropper vertically and transfer 1 drop of whole blood(approximately 35μl) to the specimen well(S) of the test device, then add 2 drops of buffer (approximately 70μl) and start the timer .
2. Test Results
Wait for the colored line(s) to appear. Read results at 15 minutes. Do not interpret the result after 20 minutes.
