Hair screening is now viewed as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug usage by embedding biomarkers within the hair fiber as it grows. When clipped near the roots, hair offers around a 3-month detection span for substances. Gathering hair is straightforward, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch tuft of about 200 hair strands (resembling the size of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal quantity for analysis and validation. For EtG, extra tests, and/or evaluations exceeding 10 panels, 150mg of the sample is suggested. It's advisable to weigh the sample on a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair may be used. Note that when mentioning head hair, we are solely referencing scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedure in analyzing a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of a sample within a laboratory's framework. This step confirms that the sample was correctly sealed and dispatched, allocates a unique LAN (Laboratory Accessioning Number), and addresses any supplementary data input absent from an electronic chain of custody system.
Screening serves as a rapid preliminary evaluation for substance abuse. Though Screening is a budget-friendly approach to negate drug presence in most samples, a positive screen must be verified to stand up in legal proceedings. Any samples showing initial positive results in Screening necessitate an additional verification.
If Screening indicates a presumptive positive, more hair is extracted from the original sample for the Extraction phase. Here, substances are isolated from hair at a much lower concentration than other methods (such as urine or oral swabs), marking hair drug testing as the hardest methodology to execute.
Verification of any positive screen outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo cleansing before confirmation as required. The comprehensive lab protocol from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair parameters and the standard ISO / IEC 17025 accreditations.
