Hair testing has become recognized as a significant means for detecting drug and alcohol use. Hair retains a prolonged history of alcohol and drug exposure by embedding biomarkers in the fibers of the hair as it grows. When harvested near the scalp, hair can offer up to about a 3-month period of detection for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (around the size of a #2 pencil) nearest the scalp will yield 100mg of hair, which is ideal for screening and confirmation. For more comprehensive analyses like EtG, additional panels, or 10-panel tests, 150mg of hair is advised. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair is not available, an equivalent quantity of body hair can be utilized. Scalp hair refers to head hair, whereas body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a laboratory's framework. This encompasses ensuring the sample was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data recording absent in an electronic chain of custody setup.
Screening includes an initial rapid check for drugs of abuse. Although Screening is an economical approach to exclude drug use in the majority of cases, a positive screen needs verification for court admissibility. Any samples classified as presumptively positive during Screening require further confirmation.
If Screening indicates a presumptive positive, further hair is harvested from the initial sample to prepare for Extraction. At this juncture, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), a reason why hair drug testing is the most challenging method to conduct.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are cleaned before confirmation if needed. The complete laboratory procedure from Accessioning to Confirmation is reviewed under CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
