Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. By embedding biomarkers in the strands of developing hair, it offers an extended timeline of substance usage. When sampled near the scalp, hair can indicate drug and alcohol use up to an approximate three months. Collecting hair is straightforward, relatively tamper-resistant, and conveniently shippable.
A section measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) near the scalp, can yield 100mg, which is the preferred quantity for preliminary and confirmatory analysis. For analyses including EtG, additional assessments, or those exceeding 10 panels, a sample of 150mg is advisable. Using a jeweler’s scale for weighing is suggested. If scalp hair is unavailable, an equal volume of body hair may be utilized. In discussions pertaining to head hair, we specifically mean scalp hair. Body hair encompasses all other hair forms (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test outcome involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially logged into the lab’s database. This step ensures the sample is appropriately sealed and shipped, assigns it a unique LAN (Laboratory Accessioning Number), and completes any missing data entry beyond what the electronic chain of custody provides.
Screening is a preliminary, rapid assessment for drugs of abuse. Although Screening is a cost-effective method to detect drug usage in most samples, a positive result must be verified for acceptance in legal settings. Any Screening-resulting presumptive positives require additional confirmation.
Should a sample test presumptively positive in the Screening phase, more hair from the original sample is prepared for Extraction. At this stage, substances are removed from hair in concentrations significantly lower than those in other methods (such as urine or saliva), underscoring the complexity of hair drug testing.
Verification of any positive screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation involves washing all presumptive positive samples as required. The full laboratory cycle, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
