QuStick™

Early diagnosis of Strep A infection

Overview Specification Support Documents

QuStick™ Strep A from EKF Diagnostics provides qualitative detection of Group A Streptococcal Antigen directly from patient throat specimens within five minutes.

QuStick™ Strep A is highly sensitive and has been proven to detect difficult cases that other rapid streptococcal tests may miss. Its enhanced sensitivity is due to the requirement that fewer bacterial colonies be present to provide a positive result.

This means that Strep A can be diagnosed earlier, allowing patients to be treated quicker and more cost-effectively.

Strep A kits use a simple dipstick format. Each kit includes pouched test strips, reagents A and B, positive and negative external controls, polyester throat swabs, extraction tubes, and a pictorial user’s guide.

QuStick™ Strep A kits from Stanbio Chemistry are CLIA-waived and have a shelf life of 20 months.

Early diagnosis of Strep A infection means more cost-effective treatment and increased patient satisfaction.
