Test Procedure Questions
How does the test work?
The test is a lateral flow chromatographic immunoassay for the qualitative detection of an identified drug or the identified drug metabolites in human urine. The S.V.T. test is a semi-quantitative color comparison screen for the detection of adulterants.
If the test is used before the refrigerated specimen reaches room temperature, is the result reliable?
No. If refrigerated, the test and the specimen must be at room temperature (15-30 degrees C) before the test is performed. Specimen at body temperature does not need to reach room temperature before running the test.
What factors could cause the test to be invalid?
Improper testing procedure, unsealed packaging, damaged membrane and unsuitable specimens could cause the test to be invalid.
If the test strip was removed from the foil pouch and dropped on the floor prior to using it, will it still work?
If the test is intact and the exposed membrane in the reaction window was not damaged, it can still be used and expected to function properly.
How many tests is it possible to run at a time?
It depends on the proficiency of the user. However, even in experienced hands, we do not recommend running more than 10 tests at a time.
