Hair analysis has emerged as an effective instrument for identifying drug and alcohol usage. Hair captures long-term evidence of alcohol and other substances by embedding biomarkers within the strands as they grow. When gathered from near the scalp, hair can reveal a detection period of up to around three months for alcohol and various drugs. Hair collection is straightforward, tricky to tamper with, and easily mailed.
A hair sample of 1.5 inches, containing approximately 200 strands (about the size of a #2 pencil) nearest to the scalp, yields 100mg, which is the preferred sample size for both screening and confirmation. For EtG, additional tests, and tests over 10 panels, 150mg of the sample is advisable. We advise using a jeweler’s scale to weigh the sample. If scalp hair isn't available, a similar amount of body hair can be used. Note that head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result comprises four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the beginning of processing a sample within a lab's system. This step involves verifying accurate sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry outside of an electronic chain of custody system.
Screening performs an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient approach to dismiss drug use for most samples, confirmation is required for any positive trial to be legally viable in court. Samples that show presumptive positivity in the Screening phase need subsequent confirmation.
In cases where a sample shows presumptive positivity during Screening, additional hair is taken from the initial sample and prepped for Extraction. This phase involves isolating drugs from hair at a much lower concentration than other methods (e.g., urine or oral fluid), resulting in hair drug screening being the most complex method to conduct.
Confirmation of any positive result from the screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleaned as needed. The entire lab workflow from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and in line with ISO / IEC 17025 standards.
Advantages of hair drug testing:
