Hair evaluations have emerged as a potent method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and various substances by embedding biomarkers within the hair's fibers as it grows. When obtained near the scalp, hair can offer a detection span of up to roughly three months for alcohol and drugs. Hair is straightforward to collect, somewhat complex to tamper with, and convenient to transport.
A segment of 1.5 inches, comprising approximately 200 hair strands (equivalent to the thickness of a #2 pencil) closest to the scalp, will yield 100mg of hair, which is the optimal source for assessment and validation. For EtG, extra tests, and/or examinations exceeding 10 panels, a specimen amounting to 150mg is advisable. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair is absent, a comparable amount of body hair might be gathered. When discussing head hair, it specifically pertains to scalp hair only. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
There are four essential stages in the laboratory procedure for drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into a lab's system initially. This step confirms the appropriate sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and fulfills any extra data entry that an electronic chain of custody system may not cover.
Screening serves as an initial swift assessment for drugs of abuse. Although Screening is an economical method to eliminate drug usage in most samples, a positive result necessitates further confirmation for legal admissibility. Any samples testing preliminarily positive during Screening require a further verification process.
When a sample tests preliminarily positive in the Screening phase, more hair is extracted from the initial specimen and set up for Extraction. During this phase, drugs are isolated from hair at a significantly lower concentration than through other methods (such as urine or oral fluid), which makes hair drug testing the most challenging method to execute.
Confirmation of any positive Screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo cleansing prior to confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the endorsement of ISO / IEC 17025 standards.
