Hair testing has become recognized as a potent means for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug history by embedding biomarkers within the fibers as the hair grows. When taken from near the scalp, hair can offer a detection period spanning up to about 3 months for alcohol and other substances. Hair collection is straightforward, relatively tough to tamper with, and convenient for transport.
An optimal sample for screening and confirmation consists of a 1.5-inch sample of roughly 200 hair strands (similar in width to a #2 pencil) from the scalp, yielding 100mg of hair. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advisable. It's best to weigh the sample with a jeweler's scale. If scalp hair is not an option, a comparable amount of body hair can be collected. The term head hair pertains exclusively to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
There are four primary stages in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary entry of a sample into the lab's system. This step includes ascertaining that the sample was correctly sealed and transported, generating a unique LAN (Laboratory Accessioning Number), and doing any supplementary data entry not captured by an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of abuse. While Screening offers a cost-efficient means to exclude drug use in most samples, a positive screen requires confirmation to stand in court. Any samples that preliminarily test positive in Screening necessitate a secondary verification.
If a specimen tests presumptively positive at the Screening stage, additional hair is drawn from the original sample and made ready for Extraction. During this step, drugs are isolated from hair at much lower concentrations than in other techniques (e.g., urine or oral fluid), accounting for the complexity of hair drug screening.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive receive a wash as necessary before confirmation. The complete laboratory process from Accessioning to Confirmation is subjected to review under the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
