Hair tests have gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term recorder of alcohol and other drugs by capturing biomarkers in the fibers of the developing hair strand. When taken from near the scalp, hair can offer nearly a 3-month timeframe for detecting alcohol and other drugs. Hair is easy to collect, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal amount for screening and validation. For tests like EtG, add-ons, and/or those above 10 panels, 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is unavailable, a comparable quantity of body hair may be used. When we mention head hair, it refers specifically to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result primarily involves four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the primary processing of a sample into a lab's system. This entails confirming that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data entry lacking in an electronic chain of custody system.
Screening performs an initial rapid check for substances of abuse. While Screening serves as an economical way to discard drug use in most cases, a positive result requires confirmation for legal admissibility. Any samples that test presumptively positive in Screening need a secondary confirmation.
Should a sample show a presumptive positive in Screening, more hair is drawn from the initial sample and prepared for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging approach to execute.
Any positive results from screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
