Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug intake by encasing biomarkers inside the fibers of the hair as it grows. When gathered near the scalp, the hair can offer nearly a three-month detection period for alcohol and other substances. Collecting hair is straightforward, reasonably hard to tamper with, and convenient to transport.
A 1.5-inch segment of about 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, and tests more comprehensive than 10 panels, a specimen of 150mg is suggested. It is advisable to weigh the sample on a jeweler's scale. If scalp hair cannot be acquired, an equivalent amount of body hair can be used. References to head hair specifically denote scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key phases involved in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of processing a sample within a lab's system, which involves verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that isn't captured by an electronic chain of custody system.
Screening is an initial swift procedure for detecting substances of abuse. Although Screening is an affordable method for eliminating drug usage in the majority of samples, positive results must be confirmed for court acceptability. Samples that screen positive require additional confirmation.
If a sample shows a presumptive positive in Screening, extra hair is taken from the initial sample for Extraction. During this phase, drugs are retrieved from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), rendering hair drug testing the most complex methodology to execute.
Confirmation of any positive findings from the screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
