Hair analysis is now recognized as an effective method to uncover drug and alcohol consumption. Hair captures a prolonged record of substances by holding onto biomarkers within the fibers of the growing strand. When obtained near the scalp, hair can reveal exposure to substances over a period of up to about three months. Hair collection is straightforward, somewhat resistant to tampering, and uncomplicated to transport.
A 1.5-inch length consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp amounts to 100mg, which is the optimal sample size for evaluation and verification. For tests involving EtG, additional substances, and/or more than 10 panels, it is suggested to gather 150mg of hair. Using a jeweler’s scale to weigh the specimen is advisable. Should head hair be unavailable, an equivalent quantity of body hair can be taken. When referencing head hair, we specifically mean scalp hair only. Body hair encompasses all other types of hair (facial, axillary, etc.).
Examination Procedure
The core steps in the laboratory processing of drug test results encompass: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is first entered into the laboratory’s system. This phase verifies the sample's proper sealing and shipment, assigns it an anonymous LAN (Laboratory Accessioning Number), and completes any supplementary data not supplied by an electronic chain of custody system.
Screening is a preliminary assessment for drug abuse. While Screening is a cost-effective strategy to exclude drug use in the majority of samples, a positive result must be confirmed for legal acceptance. Any samples with a provisional positive result in Screening require further confirmation.
When a sample shows a tentative positive during Screening, additional hair is extracted from the original sample for the Extraction stage. Here, substances are obtained from hair at a substantially lower concentration than other methods (e.g., urine or oral fluid), underscoring why hair drug screening presents complex challenges.
GC/MS, GC/MS/MS, or LC/MS/MS methods are employed to verify any positive Screening outcomes. All samples that show provisional positivity are washed prior to verification as per requirement. From Accessioning to Confirmation, the whole laboratory process is evaluated under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
