The GIARDIA/CRYPTOSPORIDIUM QUIK CHEK test is a rapid membrane enzyme immunoassay for the simultaneous qualitative detection and differentiation of Giardia cyst antigen and Cryptosporidium oocyst antigen in a single test device. It is intended for use with human fecal specimens from patients with gastrointestinal symptoms to aid in the diagnosis of Giardia and/or Cryptosporidium gastrointestinal infection. The test results should be considered in conjunction with the patient history.

The sample is added to a tube containing a mixture of Diluent and Conjugate. The diluted sample-conjugate mixture is added to the Sample Well and the device is allowed to incubate at room temperature for 15 minutes. During the incubation, parasite antigens in the sample bind to the antibody-peroxidase conjugates. The antigen-antibody-conjugate complexes migrate through a filter pad to a membrane where they are captured by the immobilized antibodies in the test lines. The Reaction Window is subsequently washed with Wash Buffer, followed by the addition of Substrate and a 10 minute incubation period.

The Giardia reaction is examined visually for the appearance of a vertical blue line on the right side (Giar) of the Reaction Window. A blue line indicates a positive test. The Cryptosporidium reaction is examined visually for the appearance of a vertical blue line on the left side (Cryp) of the Reaction Window. A blue line indicates a positive test. A positive “C” reaction, indicated by a vertical dotted blue line under the “C” portion of the Reaction Window, confirms that the test is working properly and the results are valid.
