Utilizing hair testing has emerged as an essential method for identifying substance and alcohol consumption. Hair carries a comprehensive record of alcohol and drug usage due to the entrapment of biomarkers within the strands as they grow. If collected near the scalp, hair can offer a detection period of up to three months for alcohol and drugs. The collection of hair is straightforward, somewhat resistant to alteration, and convenient for transportation.
Taking a sample of 1.5 inches, approximately equivalent to 200 strands of hair (roughly the size of a #2 pencil) closest to the scalp yields a 100mg sample, ideal for screening and verification. For EtG, add-ons, and examinations exceeding 10 panels, it's suggested to collect 150mg of the sample. Measuring the sample on a jeweler’s scale is advisable. If scalp hair is not present, an equivalent volume of body hair may be used. The term “head hair†specifically denotes scalp hair. Body hair refers to all types other than scalp (facial, underarm, etc.).
Process Overview
The laboratory procedure for processing a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample’s initial processing into the laboratory's framework. The procedure ensures the sample is sealed and shipped correctly, assigns a LAN (Laboratory Accessioning Number) randomly, and completes any additional data input absent in an electronic chain of custody system.
Screening entails a preliminary rapid evaluation for drug abuse. While Screening serves as a cost-efficient method to exclude drug use in most samples, a favorable result requires confirmation to be valid legally. All samples providing a preliminary positive in Screening must undergo secondary verification.
Should a sample show a presumptive positive at the Screening phase, further hair is extracted from the original sample for preparation in the Extraction stage. During this phase, drug substances are retrieved from hair at substantially lower concentrations than those in other techniques (e.g., urine or oral fluid); hence, hair drug screening is the most demanding method to execute.
Verification of any positive result from screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples with presumptive positives are cleansed if necessary. The full laboratory course from Accessioning to Confirmation is monitored under both the CAP (College of American Pathologists) Hair standard and the accreditation under ISO / IEC 17025 norms.
