Hair analysis has emerged as an effective means for detecting drug and alcohol use. Hair retains a long-term record of substances by incorporating biomarkers into its growing strands. When taken near the scalp, it provides a 3-month period of detection for alcohol and drugs. Hair collection is easy, difficult to tamper with, and convenient for transport.
A 1.5-inch segment consisting of around 200 hair strands (comparable to a #2 pencil thickness) closest to the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, additional tests, or panels beyond 10, 150mg of the sample is suggested. Using a jeweler’s scale to weigh the sample is advised. If scalp hair is lacking, a similar amount of body hair is suitable. When mentioned, head hair indicates scalp hair. Other hair types (facial, axillary, etc.) are termed body hair.
Process Overview
The primary steps in the lab analysis of drug tests include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing within a lab’s system. This includes ensuring proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing data not available through an electronic chain of custody system.
Screening offers a preliminary check for drugs of abuse. Though Screening is a cost-effective way to eliminate drug usage for most samples, any positive result requires confirmation to be court-worthy. Samples indicating presumptive positive in Screening must undergo secondary confirmation.
If a sample tests presumptive positive during Screening, additional hair is taken from the initial sample for Extraction. Drugs are extracted from hair at much lower concentrations compared to other methods (like urine or oral fluid), making hair testing particularly challenging.
Confirmation of positive Screening involves techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as necessary. The comprehensive lab process, from Accessioning to Confirmation, undergoes review under the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
