Hair testing has evolved into a robust method for identifying drug and alcohol consumption. Hair captures a comprehensive record of substance use by embedding biomarkers within the strands of growing hair. By obtaining hair close to the scalp, it can offer an approximate 3-month detection scope for substances like alcohol and drugs. Hair is straightforward to collect, hard to tamper with, and easy to transport.
A 1.5-inch segment comprising around 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred sample size for both screening and verification. For EtG, add-ons, or tests exceeding 10 panels, it's advised to use 150mg of the sample. The sample should be weighed using a jeweler’s scale. In cases where scalp hair isn't available, a comparable volume of body hair can be used. References to head hair imply scalp hair exclusively. Alternately, body hair includes all other types of hair (such as facial, axillary, etc.).
Process Overview
The key stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into the lab’s system. This process ensures the sample is properly sealed and delivered, assigns a random LAN (Laboratory Accessioning Number), and completes any pending data entry absent from an electronic chain of custody system.
Screening provides an initial rapid evaluation for drug abuse. Although Screening is an affordable approach to dismiss potential drug usage mostly, a positive screen must be verified to hold value in court. Presumptive positive samples in Screening require a follow-up confirmation.
Should a sample appear presumptively positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are removed from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluids), thus making hair drug screening the most challenging to execute.
Any positive Screening outcome is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation as necessary. The full lab process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair classification in addition to the ISO / IEC 17025 accreditation standards.
