Going Through the wondfo strep a self-Test Process

Allow the device and buffers to equilibrate to room temperature (10~30°C) prior to testing.

Add 4 drops of buffer A and 4 drops of buffer B respectively into the extraction tube and fully mix. The color of mixed liquid should become yellow.


Collect the throat swab specimen with the sterile swab that is provided in the kit. Testing
should be ideally performed immediately after the specimens have been collected.


Place the specimen extraction swab into the tube. Swirl the swab for ten times. Leave the swab
in the tube for one minute. Then remove the swab while squeezing the swab head against the
inside of the extraction tube as you remove it to expunge as much liquid as possible from the swab.
Discard the swab.


Remove the test cassette from its sealed pouch by tearing at the notch and place it on a clean, dry,
level surface. Add 3 drops of mixed liquid specimen from the extraction tube to the sample well
(with an arrow mark) of the test cassette by inverting and squeezing the tube as show.


Wait for 10 minutes and read the results. Do not read results after 15 minutes.

Results Interpretation

After about 10 minutes, you should have your results ready, with three possible outcomes. It can either turn out positive, negative, or invalid. The following is how they will come out and how to interpret them:

Negative Test Result

If only one colored band appears in the control (C) region, no color band appears in the test region,
the result is negative. It indicates that the concentration of the group A streptococcal antigen is zero
or below the detection limit of the test.

Positive Test Result

If two color bands are visible both in the test (T) band and the control (C) band, the result is positive.
It indicates that you may be in a stage of Strep A infection and should consult with your doctor.

Invalid Test Result

No visible band at all, or there is a visible band only in the test region but not in the control region.
This is an indication of procedure error and/or that test reagent deterioration has occurred. Repeat
test with a new test kit. If test still fails, please contact the distributor or the store where you bought
the product, with the lot number.

Group A Streptococcus is one of the most significant human pathogens causing acute:

Why should I test for Strep A?

It is very important to differentiate streptococcal infection from other etiologic agents (e.g., viral, mycoplasmal,
or chlamydial) so that appropriate treatment can be sought.

Early diagnosis and treatment of group A streptococcal pharyngitis infections will reduce the severity of symptoms and further complications such as rheumatic fever and glomerulonephritis.
