Hair tests have gained recognition as an effective means for identifying drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol use by capturing biomarkers in the strands of growing hair. If collected near the scalp, hair can reveal drug and alcohol use over an approximate 3-month period. Hair is straightforward to gather, relatively hard to tamper with, and convenient to transport.
A 1.5-inch section containing about 200 strands (comparable to a #2 pencil's thickness) proximal to the scalp yields 100mg of hair, the optimal quantity for analysis. For EtG, supplemental/extended tests exceeding 10 panels, a quantity of 150mg is advised. We advise utilizing a jeweler’s scale for specimen measurement. If scalp hair isn't accessible, an equivalent amount of body hair can be utilized. "Head hair" specifies scalp hair only, while "body hair" encompasses all other forms (e.g., facial, axillary).
Process Overview
The laboratory analysis of a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample within the lab's system. This process verifies the proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not covered by an electronic chain of custody system.
Screening executes an initial scan for drugs of abuse. Although Screening is an economical method to exclude drug use for most samples, a positive outcome requires confirmation to be legally valid. Samples with presumed positive results in Screening necessitate an additional verification step.
For samples deemed presumptively positive during Screening, an additional hair portion is extracted from the original sample and prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug testing the most intricate methodology to conduct.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are washed prior to confirmation as needed. The full laboratory process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
