Hair testing has grown to be recognized as a vital instrument for identifying drug and alcohol consumption. Hair holds a long-term record of alcohol and drug use by embedding biomarkers within the strands of the growing hair. When retrieved near the scalp, hair can offer nearly a 3-month detection timeframe for alcohol and drugs. Hair collection is straightforward, somewhat tough to tamper with, and convenient for shipment.
A 1.5-inch segment of roughly 200 hair strands (approximately the width of a #2 pencil) near the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale for weighing is recommended. In the absence of scalp hair, a comparable quantity of body hair is acceptable. "Head hair" refers exclusively to scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four primary steps in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial entry of a sample into a lab’s system. This step checks that the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry that isn’t supplied by an electronic chain of custody mechanism.
Screening acts as a swift preliminary check for substance abuse. While Screening is a cost-effective strategy for excluding drug use in most samples, a positive outcome requires further confirmation to be valid in court. Any samples that test presumptively positive during Screening necessitate subsequent confirmation.
If a sample is deemed presumptively positive in the Screening phase, more hair is extracted from the original sample and prepped for Extraction. At this stage, drugs are extracted from hair at a considerably lower concentration than other methods (e.g., urine or oral fluid), explaining why hair drug screening poses the highest level of complexity among testing methodologies.
Confirmation for any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS methods. Every presumptive positive sample is washed before Confirmation, if necessary. The comprehensive lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation along with accreditation to ISO / IEC 17025 standards.
