How the Strep A Rapid Test Works
The test uses antibodies specific to Group A Streptococcus carbohydrate antigen. After the extracted throat swab specimen is added, it migrates along the test membrane and reacts with the corresponding antibodies.
A colored line in the test region indicates the presence of Strep A antigen. The control line confirms proper test operation. This visual immunoassay provides qualitative results without measuring the antigen concentration.
The test is intended to aid in identifying Group A Streptococcal infection, including suspected streptococcal pharyngitis.
Specimen Collection and Test Procedure
Collect a throat swab from the posterior pharynx, tonsils and other inflamed areas using the sterile swab supplied with the kit.
Place the swab into the extraction tube containing buffer and roll it at least 10 times. Add 3 drops (approximately 100 μL) of extracted specimen to the test well. Read the result at 15 minutes. Do not interpret the test after 20 minutes.
For specimen handling, collected swabs can be stored in a clean, dry plastic tube for up to 8 hours at room temperature or 72 hours at 2–8°C.
Each kit includes:
- Test devices
- Sterile swabs
- Workstation
- Extraction tube with buffer
- Package insert
A timer is required separately.
The test is for professional in vitro diagnostic use. Only the supplied sterile swabs have been validated for this product. Negative results must be confirmed by culture.
