Reliable IVD gamma-butyrolactone γ-Hydroxybutyric acid Rapid Test Cassette ( Urine ) With CE Certification DGHB-102

Reliable IVD G/HB gamma-butyrolactone Rapid Test Cassette (Urine) with CE certification-DG/HB-102

Applications:

The G/HB gamma-butyrolactone Rapid Test Cassette is a rapid biochemical-based assay to detect the presence of G/HB in urine and provide a presumptive result for presence of G/HB in urine at concentrations above 10 ug/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.

Description:

γ-Hydroxybutyric acid (G/HB), also known as 4-hydroxybutanoic acid, is a naturally occurring neurotransmitter and a psychoactive drug. G/HB has been used in a medical setting as a general anesthetic and as a treatment for cataplexy, narcolepsy, and alcoholism.[1][2] It is also used illegally as an intoxicant, to try to increase athletic performance, and as a date rape drug.[3] It is commonly used in the form of a salt, such as sodium γ hydroxybutyrate (Na.G/HB, sodium oxybate) or potassium γ-hydroxybutyrate (K.G/HB, potassium oxybate).
Urine is often the preferred specimen for routine drug abuse monitoring purposes. Both γ-butyrolactone (GBL) and 1,4-butanediol are converted to G/HB in the body. [4] [5] [6] Other liquids such as suspected spiked drinks can also be tested. However, cross-reactivity with Ascorbic Acid and Alcohol need to be taken into account, while interpreting the test results.

How to use?

Allow the test, urine specimen, and/or controls to reach room temperature (15-30°C) prior to testing.

1. Remove the test cassette from the sealed pouch and use it within 30 minutes. Observe the reactive pad on the central window of the cassette. If the reaction pad has a purple color before applying urine sample, do not use.

2. Place the test cassette on a clean and level surface. Add 1 drop of G/HB Buffer and then add 2 drops of specimen to the specimen well and start the timer.

3. Initial Results may start showing up at 5 minutes for higher concentrations. However, read test results at 10 minutes to detect lower concentrations of G/HB near the cut off of 10μg/ml. Read the results by comparing the color in Test area (Reagent area) with color card provided in the kit.
Note: It is suggest not using the buffer, beyond 30 days after opening the vial.

INTERPRETATION OF RESULTS

/

Positive: The G/HB Rapid Test Cassette will produce a color change in the presence of G/HB. The color will range from light purple color at 10ug/ml of G/HB to a dark purple color greater than or equal 50ug/ml of G/HB .

Negative: When the G/HB Rapid Test Cassette shows no color change or a color less intense than the color specifying 10 ug/ml of G/HB, it should be interpreted as a negative result indicating that G/HB has not been detected.

Invalid: If the color pad has a purple color before applying urine sample, do not use the test.

NOTE: A result where the outer edges of the color pad produces a slight color but the majority of the pad remains colorless the test should be repeated to ensure complete saturation of the pad with specimen.
The test is not reusable.
