As a robust method, hair testing has gained recognition for identifying drug and alcohol consumption. By embedding biomarkers in the fibers as hair grows, it provides a long-term record of alcohol and drug use. When taken near the scalp, this hair enables a detection window of up to three months for alcohol and drugs. Hair collection is straightforward, resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches, composed of roughly 200 hair strands (comparable to a #2 pencil in size), yields 100mg of hair, the optimal quantity for screening and confirmation. For EtG, additional tests, and panels exceeding 10, a specimen of 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. If there is no scalp hair available, an equivalent amount of body hair can be utilized. 'Head hair' specifically refers to hair from the scalp, whereas 'body hair' includes all other hair types (facial, axillary, etc.).
Process Overview
The procedure for laboratory processing of drug test outcomes involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the early stages of integrating a sample into the laboratory's system. This verifies proper sealing and shipping of the sample, attaches a unique LAN (Laboratory Accessioning Number), and completes any necessary data input that's not fulfilled by an electronic chain of custody.
Screening conducts a preliminary rapid assessment for the presence of drugs of abuse. Although Screening is effective cost-wise to eliminate drug usage in most samples, confirmed approval is necessary for any positive screenings to be legally valid. Consequently, any samples that indicate a presumptive positive in Screening undergo secondary confirmation.
Should a sample show presumptively positive results at the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair in much lower concentrations than in methods such as urine or oral fluid, making hair drug screening the most complex methodology to execute.
Positive findings in the screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked presumptively positive undergo necessary washing before confirmation. The entire laboratory procedure from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair standards and complies with ISO / IEC 17025 accreditation.
Pros of hair drug testing:

Note: Commonly termed as "hair follicle tests", the analysis is actually conducted on the hair strand rather than the follicle beneath the scalp.
