EASY Line Barbiturates Test is a chromatographic immunoassay for the qualitative detection of Barbiturates (BAR) and BAR metabolites in human urine at the cut-off 300 ng/mL concentrations. This assay provides only a preliminary qualitative test result. Use a more specific alternate quantitative analytical method to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Apply clinical and professional judgment to BAR test result, particularly when preliminary positive results are obtained. This one step test is very sensitive and only takes about 5 minutes.

Test results are read visually without any instrument. For “in vitro” diagnostic use only.

EASY Line Barbiturates Test is a competitive immunoassay utilizing highly specific reactions between antibodies and antigens for the detection of Barbiturates and their metabolites in human urine.

EASY Line Barbiturates Test is a rapid urine screening test that utilizes monoclonal antibodies to selectively detect elevated levels of specific drugs in urine without any instrument.

Barbiturates are central nervous system depressants. They are used therapeutically an sedatives, hypnotics, and anticonvulsants. Barbiturates are almost always taken orally as capsules or tablets. The effects resemble those of intoxication with alcohol. Chronic use of barbiturates leads to tolerance and physical dependence. Short acting Barbiturates taken at 400 mg/day for 2-3 months can produce a clinically significant degree of physical dependence. Withdrawal symptoms experienced during periods of drug abstinence can be severe enough to cause death. Only a small amount (less than 5%) of most Barbiturates are excreted unaltered in the urine.

The approximate detection time limits for Barbiturates are:

  • Short acting (e.g. Secobarbital) 100 mg PO (oral) 4.5 days

  • Long acting (e.g. Phenobarbital) 400 mg PO (oral) 7 days

The Multiple Drugs of Abuse Rapid Tests yields a positive result when the Barbiturates in urine exceed 300 ng/mL.

 

EASY Line Barbiturates Test is an immunoassay based on the principle of competitive binding. Barbiturates which may be present in the urine specimen compete against its drug conjugate for binding sites on their specific antibody.

During testing, a urine specimen migrated upward by capillary action. Barbiturates, 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 Barbiturates-protein conjugate and a visible coloured line will show up in the test line region of the strip. The presence of Barbiturates above the cut-off concentration will saturate all the binding sites of the antibody. Therefore, the coloured line will not form in the test line region.

A Barbiturates-positive urine specimen will not generate a coloured line in the specific test line region of the strip because of drug competition, while a Barbiturates-negative urine specimen will generate a line in the test line region because of the absence of drug competition.

To serve as a procedural control, a coloured line will always appear at the control line region, including that proper volume of specimen has been added and membrane wicking has occurred.

The kit contains reagents for 30 tests in cassette (code 20007-1).

Accuracy

A side-by-side comparison was conducted using EASY Line Barbiturates Test and other commercially available rapid drug tests. Testing was performed on 120 samples. All the presumptive positive and negative results were confirmed by GC/MS. The following compounds were quantified by GC/MS and contributed to the total amount of drugs found in presumptive positive urine samples tested.

Forty (40) clinical samples were run using EASY Line Barbiturates Test by an untrained operator at a Professional Point of Care site. Based on GC/MS data, the untrained operator obtained statistically similar Positive Agreement, Negative Agreement and Overall Agreement rates as trained laboratory personnel.

*Note: TCA was based on HPLC data.

Reproducibility

Reproducibility studies were carried out using commercially available standards. Each standard was diluted in normal, drug-free urine to give the appropriate concentration. Each specimen, at each concentration of analyte, was tested four times daily, in duplicate, for five consecutive days. A total of 40 determinations were made at each concentration. The results are given below:
