Hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by retaining biomarkers in the strands of growing hair. When obtained close to the scalp, hair can offer up to a nearly 3-month detection period for alcohol and drugs. Hair is straightforward to gather, relatively tamper-resistant, and convenient to transport.
A sample measuring 1.5 inches and containing approximately 200 hair strands (roughly the size of a #2 pencil) closest to the scalp will result in 100mg of hair, which is the perfect amount for assessment and verification. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the sample is advised. It's advisable to use a jeweler’s scale for weighing the sample. If scalp hair isn't available, a comparable quantity of body hair may be taken. When discussing head hair, we are specifically referring to scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The four primary phases in the laboratory handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of incorporating a sample into a laboratory's system. This phase ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry not covered by an electronic chain of custody system.
Screening performs a preliminary quick evaluation for drugs of abuse. While Screening is an efficient method to eliminate drug use in most samples, a positive result must be validated to be court-admissible. Any samples that yield a presumptively positive result in Screening need a secondary confirmation.
If a sample is presumptively positive during the Screening phase, additional hair is taken from the original sample and prepared for Extraction. During Extraction, drugs are removed from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.
Any positive screening result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are washed as needed before confirmation. The whole laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation as well as conformity to ISO / IEC 17025 standards.
