It all depends on what type of job you are going for. However the majority of companies who test their prospective employees nowadays ask them to provide urine samples as this is the most common type of analysis. If you are required to undergo a drug test before you are hired for a job, then your employers will tell you what type of test it will be.
When testing urine, the first step is to split the urine into two aliquots. The first of these two is screened by performing an immunoassay. If this urine screen comes back positive then the second aliquot is used to confirm the findings of the first sample using gas chromatography - mass spectrometry (GC-MS). All results found are passed on to a Medical Review Office (MRO) where a trained medical physician will verify the findings. If the result from the gas chromatography test comes up negative, then the MRO will tell the employer the findings. However if the test results of both the immunoassay show foreign substances, then MRO will inform the employer who will then question the employee who gave the sample to determine if there is a legitimate reason for example, prescription medication.
Hair analysis is commonly used for the testing of therapeutic and recreational drugs such as cocaine, heroin, benzodiazepines and amphetamines. Testing with hair is becoming an increasingly common method of testing for substance abuse particularly in legal proceedings when a subject has chosen not to be entirely truthful about their substance taking in the past.
Nowadays with technological advancements, on site urine tests are becoming more widely available because of their cost-effectiveness and accuracy when it comes to testing people for drug abuse. The accuracy of these on site test results do vary but some of them boast extremely high percentages of accuracy that are not far off laboratory testing.
