Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged timeline of substance use by embedding biomarkers within the strands of hair as they grow. When obtained near the scalp, hair can indicate substance use up to around a 3-month period for alcohol and other drugs. The collection process for hair is straightforward, resists tampering, and is simple to transport.
A sample measuring 1.5 inches and containing about 200 strands of hair (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferred sample size for screening and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair isn't an option, a similar amount of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" covers all other types (like facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. This step entails ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry that hasn’t been addressed by an electronic chain of custody system.
Screening is a preliminary check for substances of abuse. Although Screening is a cost-effective way to eliminate drug use in most samples, to be valid in legal contexts, a positive screen must be verified. Any samples catching a presumptive positive result in Screening necessitate additional confirmation.
Should a sample reveal a presumptive positive during Screening, additional hair is extracted from the original specimen for Extraction. In this phase, substances are extracted from hair at considerably lower concentrations than in other methods (such as urine or oral fluid), making hair drug screening the most complex method to execute.
GC/MS, GC/MS/MS, or LC/MS/MS are utilized for confirming any positive screening result. All samples with presumptive positives are washed before confirmation as necessary. The full laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
