Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drug intake by embedding biomarkers within the fibers of the hair as it grows. When clipped near the scalp, hair can deliver a detection period of up to roughly three months for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and convenient to send.
A 1.5-inch sample, around 200 strands (about the size of a #2 pencil) nearest to the scalp, equates to 100mg of hair, which is the perfect amount for both screening and confirmation. For EtG add-ons and tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is recommended. Should scalp hair be scarce, an equivalent volume of body hair can be taken. Referring to head hair implies only scalp hair. Body hair involves all other varieties (facial, axillary, etc.).
Process Overview
The core steps in laboratory processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial preparation of a sample into a lab’s framework. This step verifies that the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any other data entry absent from an electronic chain of custody.
Screening provides an initial rapid test for drugs of abuse. Though a cost-effective approach for excluding drug presence in most samples, a positive screen needs confirmation for court validity. Samples that appear positive during Screening need an additional confirmation.
If Screening indicates a sample as positive, additional hair is taken from the original sample for Extraction. During Extraction, drugs are derived from hair at far lower levels than other techniques (e.g., urine or oral fluid), making hair drug analysis the most challenging technique.
Confirmation for any positive screening is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples tentatively positive are cleaned before confirmation, as necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair specification and compliance with ISO / IEC 17025 standards.
