Hair testing is increasingly viewed as a robust method for detecting drug and alcohol use. Hair captures a long-term record of these substances by embedding biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair offers up to a 3-month detection period for alcohol and other drugs. It is straightforward to gather, moderately tough to tamper with, and convenient to transport.
A sample of 1.5 inches, comprising roughly 200 hair strands (similar to a #2 pencil in thickness) nearest to the scalp, will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a specimen weighing 150mg is advised. Measuring the specimen using a jeweler’s scale is recommended. If scalp hair isn't obtainable, a similar amount of body hair is an alternative. Head hair specifically refers to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
There are four primary steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample is introduced into a lab’s system. This step ensures the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.
Screening is a preliminary swift check for drug abuse. Although it is a cost-efficient method to exclude drug use for most samples, any positive screen must be verified for it to be legally valid. Samples with presumptive positive results in Screening will need a secondary confirmation.
Samples presuming positivity in the Screening phase lead to more hair being taken from the original specimen for Extraction. In this step, drugs are extracted at concentrations much lower than other methods (such as urine or oral fluid), making hair drug screening a challenging methodology to execute.
Confirmation of any positive screen takes place via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumed positivity are cleaned before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
