The use of hair testing has emerged as an effective instrument for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the hair as it grows, hair provides an extended historical record of alcohol and other substance use. When hair is taken near the scalp, it offers an approximate three-month detection period for alcohol and other substances. Hair is straightforward to gather, harder to adulterate, and simple to transport.
An ideal testing sample comprises 1.5 inches of about 200 hair strands (similar in size to a #2 pencil) closest to the scalp, equating to 100mg of hair. For EtG, additional testing, or more than 10 panels, 150mg of the sample is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair is inaccessible, a comparable quantity of body hair can be collected. References to head hair exclusively denote scalp hair, whereas body hair encompasses any other hair type (facial, axillary, etc.).
Process Overview
The laboratory procedures for determining a drug test result involve four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a specimen within the lab's framework. This includes verifying the proper sealing and shipment of the sample, assigning it a random LAN (Laboratory Accessioning Number), and entering supplementary data not provided by an electronic chain of custody.
Screening constitutes an initial rapid evaluation for drug abuse. As Screening is a cost-effective method to dismiss drug presence in most samples, a positive result necessitates further confirmation to be validated in a court setting. Any samples identified as presumptively positive in Screening necessitate a follow-up confirmation.
Upon detecting a presumptive positive during the Screening process, additional hair is extracted from the initial sample for the Extraction phase. At this juncture, substances are isolated from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), which underscores the complexity of hair drug screenings.
Confirmation of any positive screening outcome is verified via GC/MS, GC/MS/MS, or LC/MS/MS. All samples labeled as presumptively positive are cleansed before confirmation if required. The end-to-end laboratory operations from Accessioning to Confirmation undergo scrutiny under the CAP (College of American Pathologists) Hair designation and conform to ISO / IEC 17025 accreditation standards.
