Instruction for use, pipette,buffer,sterile lancet Principle of Test:
Immunochromatographic assay Production Performance:
Specificity: 94.3%
INTENDED USE: The TB Test Device 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℃) prior to testing. Do not open 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 and 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.
INTERPRETATION OF RESULTS
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 problem persists, please contact your local distributor.
