Multi Parameter Pipette Test

The ulti med Multi Parameter Pipette Test is a specific arrangement of different lateral flow chromatographic immunoassays for the detection of different drugs and cut-off concentrations in human urine. This assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated. Test to monitor therapeutic measures.

Principle

During testing, a urine specimen migrates upward by capillary action. A drug, if present in the urine specimen below its cut-off concentration, will not saturate the binding sites of its specific antibody. The antibody will then react with the drug-protein conjugate and a visible colored line will show up in the test region of the specific drug strip. The presence of drug above the cut-off concentration will saturate all the binding sites of the antibody. Therefore, the colored line will not form in the test region. A drug-positive urine specimen will not generate a colored line in the specific test region of the strip because of drug competition, while a drug-negative urine specimen will generate a line in the test region because of the absence of drug competition. To serve as a procedural control, a colored line will always appear at the control region, indicating that proper volume of specimen has been added and membrane wicking has occurred.

Benefits:

• adulteration parameter test available
• alcohol detection of ETG or enzymatical alcohol detection (0.2 to 3.0 per mill)
• lower sample quantity required (3 drops for each sample well)
• up to 5 single parameter or up to 15 multi parameter (considering cross reactivity)

The minimum order quantity for the test are 2,000 pieces.
