Hair testing has emerged as a significant tool for detecting drug and alcohol consumption. Hair serves as a record, providing a prolonged timeline of substance use by capturing biomarkers within the growing hair strand's fibers. When harvested near the scalp, hair offers up to roughly a 3-month period for detecting alcohol and drugs. Hair is straightforward to gather, challenging to tamper with, and convenient for shipping.
A 1.5-inch hair sample of roughly 200 strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, an optimal amount for analysis. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing the specimen is suggested. Should scalp hair be unavailable, an equivalent quantity of body hair may be substituted. "Head hair" specifically refers to scalp hair only, whereas "body hair" encompasses all other hair forms (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial processing into a laboratory's system, which includes verifying that the sample was properly sealed and shipped, assigning a random Laboratory Accessioning Number (LAN), and completing any further data entry not covered by an electronic chain of custody system.
Screening involves an initial quick check for drugs of abuse. While it is a cost-efficient method to rule out drug use in most samples, a positive screen must be confirmed to be admissible in court. Any samples that test presumptively positive in Screening do require confirmation.
If a sample is presumptively positive during the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug testing is the most complex method to perform.
Confirmation of any positive screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as necessary. The entire lab process from Accessioning through Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often called "hair follicle tests," the analysis targets the hair strand, not the follicle beneath the scalp.
