Hair analysis is now regarded as an effective means for identifying alcohol and drug consumption. Hair captures a detailed timeline of drug and alcohol intake by trapping biomarkers within the growing structure of the hair strand. When retrieved near the scalp, hair offers a detection timeline extending up to almost three months for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and uncomplicated to transport.
A hair segment measuring 1.5 inches, consisting of about 200 strands (similar in thickness to a #2 pencil) near the scalp, yields 100mg of hair, perfect for both screening and confirmation. For tests with EtG, extras, and/or those exceeding 10 panels, 150mg of the hair is advised. It's suggested to measure the hair on a jeweler's scale. In cases where scalp hair isn't accessible, an equivalent amount of body hair can be used. When mentioning head hair, we specifically mean scalp hair. In contrast, body hair encompasses other types (like facial, axillary, etc.).
Process Summary
The four fundamental laboratory steps for processing a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample into the lab's system. This process includes validating the proper sealing and shipping of the sample, issuing a random LAN (Laboratory Accessioning Number), and filling in any further data entry absent from an electronic chain of custody system.
Screening offers a rapid assessment for drugs of abuse. While Screening economically eliminates drug use for the majority of samples, a positive finding must be confirmed to be valid in legal settings. Any Screening phase presumptive positive samples require additional confirmation.
If a sample yields a presumptive positive outcome during Screening, additional hair is extracted from the original sample for the Extraction phase. In this phase, drugs are extracted from hair at substantially lower concentrations compared to other methods (like urine or oral fluid), making hair drug screening a much more complex method to conduct.
Confirmation of any positive Screening result is utilized through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair endorsement and the ISO / IEC 17025 accreditation standards.

Note: Often termed "hair follicle tests", the analysis targets the hair strand itself, not the follicle beneath the scalp.
