Hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged timeline of substance use by capturing biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair can provide up to a 3-month window for detecting alcohol and drug use. Hair collection is straightforward, resistant to tampering, and easily shipped.
A 1.5-inch sample containing approximately 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, a similar amount of body hair can be obtained. When mentioning head hair, we are specifying scalp hair exclusively. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
The primary stages in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial sample processing into the laboratory’s system. This process includes verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not provided through an electronic chain of custody system.
Screening is the initial swift examination for substances of abuse. Although Screening is a cost-efficient way to rule out substance use in most samples, a positive screen needs to be validated to be admissible in legal contexts. Any samples that are presumptively positive in Screening require a secondary confirmation.
If a sample is presumptively positive during the Screening phase, additional hair is extracted from the initial specimen for Extraction preparation. During Extraction, drugs are isolated from hair at a considerably lower concentration compared to other methods (such as urine or oral fluid), which contributes to the complexity of performing hair drug screening.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed if necessary prior to confirmation. The entire laboratory workflow from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
