When it comes to reading hair follicle drug test information, it is important to take note of the guidelines that are being followed by drug testing laboratories. Understanding and remembering these guidelines can help you pass this type of drug test by educating you on how the procedure is done and what protocols are being followed. Here are some of these guidelines.
What kind of drugs does it detect?
As mandated by the federal government, a hair drug test is designed to detect phencyclidine (PCP), methamphetamine (Ecstasy), opiates (morphine, codeine), marijuana and cocaine. This drug test can detect these types of drugs as long as they are ingested within 90 days.
How do laboratories obtain hair samples?
A sample is directly cut from the person's head using a non-contaminated scissor and is always cut as close to the scalp as possible. Though the length of the sample may depend on the policies of the laboratory, many facilities gather 90-120 hair strands that are 1.5 inches long. Hair samples from other sources such as a brush are not accepted by laboratories to ensure that the samples are not tampered in any way.
What is the protocol for people with little or no hair?
For people with limited or short hair, samples are collected from different head location in order to obtain the necessary amount. In the event that there is not enough hair in the head, body hair will be collected. Urine and other types of drug tests are ordered for people who cannot supply the required amount of hair.
