Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the strands of hair as they grow, hair offers an extended timeline of alcohol and drug use. When taken near the scalp, hair can reveal drug consumption patterns for up to a three-month period. Collecting hair is straightforward, not easily tampered with, and simple to transport.
A sample consisting of 1.5 inches from approximately 200 hairs (around the girth of a #2 pencil) close to the scalp offers 100mg of hair, which is the preferred sample amount for screening and confirmation. For EtG, additional tests, and/or testing above 10 panels, a 150mg specimen is advised. It's recommended to measure the sample using a jeweler's scale. Should scalp hair be unavailable, a similar quantity of body hair is acceptable. The term "head hair" specifically refers to scalp hair only. "Body hair" includes all other hair types (like facial or axillary hair).
Process Overview
The laboratory procedure for processing a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where the sample is integrated into the lab's system. This entails confirming the sample was properly sealed and transported, assigning it a LAN (Laboratory Accessioning Number), and completing any necessary data input not covered by an electronic chain of custody system.
Screening is a preliminary check for substances of abuse. Screening offers a cost-efficient method to eliminate drug use for most samples, but for a screen to be considered legally acceptable, positive results must be confirmed. Samples with a presumptive positive result during Screening need further verification.
If a sample tests presumptively positive during Screening, additional hair is extracted from the sample for further preparation in the Extraction phase. Here, drugs are extracted from the hair at far lower concentrations than other methods (like urine or oral fluid), which contributes to the complexity of hair drug screening.
Positive screening results are confirmed using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as required. The complete lab process, from Accessioning to Confirmation, is evaluated under both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: While often labeled as "hair follicle tests", the analysis is done on the hair strand itself, not the follicle beneath the scalp.
