Immunochromatographic assay

The (TB) Tuberculosis Test Whole Blood (Strip) is a chromatographic immunoassay (CIA) for direct qualitative detection of tuberculosis antibody in human whole blood, serum, or plasma.

Test Procedure:

1. Bring the pouched test strip to room temperature (15-30℃) before testing. Do not open the pouch until ready to perform the assay.
2. Remove the test strip from the sealed pouch. Lay it on a flat, clean, and dry surface.
3. Hold the dropper vertically and transfer 1 drop of WB/Serum/Plasma to the sample pad of the test strip. Then hold the buffer bottle vertically, add 1 drop, and start the timer.
4. Wait for the red line to appear. Read the result between 10-20minutes. Do not interpret the result after 20 minutes.

• POSITIVE: Two red lines are visible in the result area. The intensity of the test line may be weaker or darker than that of the control line. This still means a positive result.
• NEGATIVE: The control line appears in the result area, but the test line is not visible.
• INVALID: If the control line does not appear in the result area, the test results are INVALID regardless of the presence or absence of the line in the test region. (NOTE: Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for the control line failure. Review the procedure and repeat the test with a new strip. If the problem persists, contact your local distributor.)
