Urine test can be bought in many different shop and supermarkets. The majority of drug store will sell a home urine kit for just under $20.
When an employer requests a drug test from an employee, or a patient requests a drug test from a physician, the employee or patient is typically instructed to go to a collection site. The patient or employee's urine is collected at a remote location in a specially designed secure cup, sealed with tamper-resistant tape, and sent via express delivery service to a testing laboratory to be screened for drugs typically SAMHSA 5 panel.
The first step at the testing site is to split the urine into two aliquots. One aliquot is first screened for drugs using an analyzer that performs immunoassay as the initial screen. If the urine screen is positive then another aliquot of the sample is used to confirm the findings by gas chromatography - mass spectrometry methodology. If requested by the physician or employer, certain drugs are screened for individually; these are generally drugs part of a chemical class that are, for one of many reasons, considered more abuse-prone or of concern. For instance, this is due to their wide recreational use much more than similar drugs, done to oxycodone and diamorphine, both sedative analgesics. If such a test is not requested specifically, the more general test in the preceding case, the test for opiates will detect the drugs, but the employer or patient will not have the benefit of the identity of the drug.
On-site instant drug testing is becoming more widely used in those jurisdictions allowing it such as some states of the USA as a more cost-efficient method of effectively detecting drug abuse amongst employees, as well as in rehabilitation programs to monitor patient progress. These instant tests can be used for both urine and saliva testing. Although the accuracy of such tests varies with the manufacturer, some kits boast extremely high rates of accuracy, correlating closely with laboratory test results.
