Tuberculosis TB​​ Rapid Test Products Description

Products Description

TB Tuberculosis rapid test is a rapid direct binding test for the qualitative detection of antibodies to Mycobacterium tuberculosis(M.tuberculosis) antigen in human serum or plasma, as an aid in the clinical assessment of Mycobacterium tuberculosis viruses infection.

Principle of TB Tuberculosis rapid test

TB Tuberculosis rapid test uses a double antigens “sandwich principle”1 for the detection of M.tuberculosis antibody in human serum/plasma.Two recombinant Tuberculosis antigens (TB Ag 1&2) were mixed and immobilized on the test band region, and an antibody to Tuberculosis on the control band region of nitrocellulose membrane. Another Tuberculosis antigen (TB Ag 3),coupled with colloidal gold particles, is dried on a conjugate pad. During the assay,the specimen is allowed to react with the colored conjugate (antigen-colloid gold conjugate);the mixture then migrates chromatographically along the membrane by capillary action.If the specimen contains Tuberculosis antibody,the recombinant antigen immobilized on the membrane will capture the antibody-antigen-colloidal gold complex and form a colored test band on the membrane,indicating a positive result. Absence of the test band suggests a negative result.To serve as a procedural control, a colored band at control region always appears in the test area.This one step test is very sensitive and only takes about 15 minutes.Test results are read visually without any instrument.

Test Procedure - TB Tuberculosis rapid test

Allow the test device, reagents, throat swab specimen, and/or controls to reach room temperature (15-30°C) prior to testing.

1.Remove the test device from the sealed foil pouch and use it as soon as possible. Best results will be obtained if the test is performed immediately after opening the foil pouch.

2.Hold the Reagent A bottle vertically and add 4 full drops (approximately 240 mL) of Reagent A to an extraction test tube. Reagent A is red in color. Hold the Reagent B bottle vertically and add 4 full drops (approximately 160 mL) to the tube. Reagent B is colorless. Mix the solution by gently swirling the extraction test tube. The addition of Reagent B to Reagent A changes the color of the solution from red to yellow. See illustration 1.

3.Immediately add the throat swab to the extraction test tube of yellow solution. Agitate the swab 10 times in the tube. Leave the swab in the tube for 1 minute. Then press the swab against the side of the tube and squeeze the bottom of the tube as the swab is withdrawn. Discard the swab. See illustration 2.

4.Fit the dropper tip on top of the extraction test tube. Place the test device on a clean and level surface. Add 3 full drops of solution (approx. 100 µL) to the specimen well (S) and then start the timer. See illustration 3.

5.Wait for the colored line(s) to appear. Read the result at 5 minutes. Do not read the result after 10 minutes.

Positive Result:

Two colored bands appear on the membrane. One band appears in the control region (C) and another band appears in the test region (T).

Negative Result:

Only one colored band appears in the control region (C). No apparent colored band appears in the test region(T).

Invalid Result:

Control band fails to appear. Results from any test which has not produced a control band at the specified reading time must be discarded. Please review the procedure and repeat with a new test. If the problem persists, discontinue using the kit immediately and contact your local distributor.

NOTE:

1. The intensity of the color in test region(T)may vary depending on the concentration of aimed substances present in the specimen.Therefore,any shade of color in the test region should be considered positive. Besides, the substances level can not be determined by this qualitative test.

2. Insufficient specimen volume, incorrect operation procedure, or performing expired tests are the most likely reasons for control band failure.
