Hair testing is recognized as a highly effective method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and other substances by embedding biomarkers within the fibers of the growing hair strand. When hair is collected from close to the scalp, it can reveal up to approximately a 3-month detection window for alcohol and other substances. The method of collection is straightforward, relatively hard to tamper with, and convenient for shipping.
A sample of 1.5 inches containing about 200 strands of hair (equivalent to the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional panels, and/or tests exceeding 10 panels, a sample of 150mg is advised. It is recommended to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, a similar amount of body hair can be gathered. Head hair specifically refers to scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in the lab consist of Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the lab's system. This process includes ensuring that the sample was sealed and delivered correctly, issuing a random LAN (Laboratory Accessioning Number), and completing additional data entry not included by an electronic chain of custody system.
Screening involves a preliminary swift evaluation for drugs of abuse. Although Screening offers a cost-efficient method to dismiss drug use in most samples, a positive screen requires confirmation to be considered valid in a legal setting. Any samples identified as potentially positive during Screening necessitate a subsequent confirmation.
In the event a sample tests potentially positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this process, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring why hair drug screening remains the most intricate methodology to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as potentially positive undergo washing prior to confirmation if necessary. The entire laboratory process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
