Product Name

GHB Rapid Diagnostic Test

Specimen: Urine

Intended Use

The GHB Rapid Test Cassette is a rapid biochemical-based assay to detect the presence of GHB in urine and provide a presumptive result for presence of GHB in urine at concentrations above 10 μg/mL. This test provides a preliminary result only. A more specific alternate chemical method is recommended. Gas chromatography/mass spectroscopy (GC/MS) is the preferred confirmation method. Clinical consideration and professional judgment should be applied to any test result, particularly when preliminary positive screens are indicated.

Test Principle

GHB-DH catalyses the reaction of GHB and NAD to produce NADH, and a diaphorase couple tetrazoliym dye reaction results in the production of a purple dye complex. The reagents were stabilized and used to produce the test to screen for GHB in urine at 10 μg/mL.

DIRECTIONS FOR USE

Bring tests, specimens, and/or controls to room temperature (15-30°C) before use.

Remove the test from its sealed pouch, and place it on a clean, level surface. Label the test with patient or control identification. For best results, the assay should be performed within one hour.

Using the provided disposable pipette, transfer 3 drops of specimen (approximately 120 µL) to the specimen well (S) of the device and start the timer.

Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result area.

As the test begins to work, color will migrate across the membrane.

Wait for the colored band(s) to appear. The result should be read at 5 minutes. Do not interpret the result after 8 minutes

INTERPRETATION OF RESULTS

NEGATIVE:* A colored line appears in the Control region (C) and colored lines appears in the Test region (T). This negative result means that the concentrations in the urine sample are below the designated cut-off levels for a particular drug tested.

*NOTE: The shade of the colored lines(s) in the Test region (T) may vary. The result should be considered negative whenever there is even a faint line.

POSITIVE: A colored line appears in the Control region (C) and NO line appears in the Test region (T). The positive result means that the drug concentration in the urine sample is greater than the designated cut-off for a specific drug.

INVALID: No line appears in the Control region (C). Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for Control line failure. Read the directions again and repeat the test with a new test card. If the result is still invalid, contact your manufacturer.

QUALITY CONTROL

A procedural control is included in the test. A colored line appearing in the control line region (C) is considered an internal procedural control. It confirms sufficient specimen volume, adequate membrane wicking and correct procedural technique.
