Advantages of Using Multi-panel Hair Drug Test Kits

Hair drug test kits are used to detect the presence of drug in hair follicles. After urine and saliva drug test kits, these hair drug tests seem to be popular for many reasons. After consuming the drugs, they stay in the body for sometime, and later get processed in to metabolites. Thereafter, they enter the blood stream. From there they nourish the hair and get encased into the hair strands and hence can be detected using hair drug test kits. As mentioned earlier there are many number of advantages using these hair drug testing kits, which are as follows.

  • The primary importance of hair drug testing is- it can detect the drugs which are consumed 90 days before the drug test. That is hair drug tests are used for wider window drug detections.
  • Unlike all the remaining test processes like urine, saliva, it is difficult to adulterate hair drug tests, since no one can remove the metabolites of the drug which are stuck to the strands of the hair. Manipulation is difficult which leads to accurate results.
  • Hair drug test is non – invasive collection procedure.
  • A small sample is cut as close to the scalp of 1.5inch, which will give the drug consumption history of 90 days.
  • More effective than urine drug test in identifying low-level drug use.
  • The drugs which are usually detected using this test are most popular like Cocaine, marijuana, opiates, methamphetamine, and phencyclidine (PCP). These are five drug classes which are approved by the Federal Government.
  • Test results will be more effective and accurate and hence, less chances of false positives and false negatives.
  • Since the hair samples are washed extensively to remove all the external contamination, exposing to the marijuana smoke or the second hand smoke of such drugs will not affect the test results.
  • Above all it is cost effective.


These are the few advantages of using hair drug tests which ultimately lead to accurate results.
