Substance Abuse Testing


Instant urine drug test is cost-effective and easy to implement. Improvements over the years have made the results comparable to laboratory results. Although it is even better to get a confirmation of laboratory positive results, instant urine tests are an attractive alternative to sending all the employee samples to a laboratory for testing.


The detection window in the urine samples is as early as two hours after use to 72 hours after use, depending on the individual's metabolism and the drug. The results of a urine test indicate the presence or absence of certain drugs or metabolites of drugs in the urine. Metabolites are drug residues that remain in the system for some time after the effects of the drug have worn off. A positive urine test does not necessarily mean that the subject was under the influence of drugs at the time of the test. Instead, it detects and measures the use of a particular drug over the past days.

Testing Procedure

A sample collection process is performing on the customer’s locations. It is following with full Chain of Custody protocol with uniform collection procedures and integrity of analysis. We use split specimen urine drug testing instead of regular one. The urine sample is split into two vials and delivered to SAMHSA certified laboratory for urine testing and analysis. One of these vials is tested upon arrival at the lab and the other is stored frozen for litigation purposes.

Samples that screen positive will then be tested further by GC-MS, or LC-MS (Gas Chromatography- Mass Spectrometry, or Liquid Chromatography-Mass Spectrometry), which can identify with precision the drugs present in the sample. In this case the person who submitted the sample can request a new test ant the 2nd vial is sent to a Medical Review Officer.
