Description

Requires

Pipetter (40 and 80μL); timer; disposable micro-centrifuge tubes, test tubes or microtiter plate

Prescription-use laboratory assay aids in the diagnosis of crytococcosis

Immochromatographic test system for qualitative or semi-quantitative detection of capsular antigens of Cryptococcus species complex in serum and cerebral spinal fluid.

  • No specimen treatment needed
  • 10-Minute total test time
  • High sensitivity and specificity — twice as fast, and with greater sensitivity, compared to latex agglutination
Dipstick sandwich immunochromatographic assay
  • Specimens and specimen diluent are added into a test tube or other reservoir
  • Lateral flow device is placed into the reservoir
  • Specimen wicking captures gold-conjugated, anti-CrAg monoclonal antibodies and gold-conjugated control antibodies deposited on test membrane
  • CrAg present in the specimen binds to the gold-conjugated, anti-CrAg antibodies
  • Antibody-antigen complex continues to wick up the membrane and interacts with test line containg immobilized anti-CrAg monoclonal antibodies
  • Gold-labeled antibody-antigen complex forms a sandwich at the test line causing a visible line to form
  • Positive test results create two lines (test and control)
  • Negative test results form only one line (control)
  • Failed test exists if a control line fails to develop

Assay Kit Content

  • 6.5mL LF Specimen Diluent: Glycine-buffered saline containing blocking agents and a preservative
  • Pack of 50 CrAg LF Test Strips in desiccant vial
  • 1mL CrAg Positive Control: Glycine- buffered saline spiked with cryptococcal antigen (strain 184A – clinical isolate from Tulane University (Infection & Immunity, June 1983, p. 1052-1059))
  • Package insert

For optimal results, sterile nonhemolyzed serum should be used.
