BD Macro-Vue™ RPR (Rapid Plasma Reagin) 18mm Circle Card Tests: Antigen Suspension
Nontreponemal testing procedure for the serologic detection of syphilis
Brand: BD 270309
Alert:
RPR Card Antigen Suspension contains sodium azide, which is harmful if swallowed. Contact with acids liberates very toxic gas. After contact with skin, wash immediately with plenty of water. Sodium azide may react with lead and copper plumbing to form highly explosive metal azides. On disposal, flush with a large volume of water to prevent azide buildup.
Description
RPR Card antigen suspension is a carbon particle cardiolipin antigen1 which detects reagin, an antibody-like substance present in serum or plasma from syphilitic persons. The reagin binds to the test antigen, which consists of cardiolipin-lecithin-coated cholesterol particles, causing macroscopic flocculation.
- Recommended when venous blood collection employed and a large volume of serum available, such as in public health and clinical laboratories
- Various RPR Card Test kits are available with all the necessary supplies to perform the procedure
- A wide array of kit sizes are available
- Antigen and testing components may be purchased separately
- Test cards are available in 10, 15 and 30 spot cards
- BD Dispenstirs™ are included with tests to serve as pipetting and spreading devices
- When specimen contains antibody, flocculation occurs with coagglutination of carbon particles of RPR Card antigen, which appear as black clumps against white background of card
- Nonreactive specimens appear to have an even light-gray color
- In special situations when nontreponemal test results are needed rapidly and specimen is collected as EDTA plasma, RPR 18mm Circle Card Test can be used if test is performed within 24 hours
