Hair testing is now recognized as a potent means for identifying drug and alcohol use. By embedding biomarkers within the fibers of hair as it grows, hair offers a comprehensive timeline of alcohol and drug consumption. When taken near the scalp, hair can reveal up to a 3-month period of substance use. Its collection is straightforward, a challenge to tamper with, and easily transported.
A hair sample measuring 1.5-inch with approximately 200 strands (comparable in size to a #2 pencil) nearest to the scalp delivers 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is recommended. We advise using a jeweler’s scale for weighing the specimen. If scalp hair is not accessible, a similar quantity of body hair may be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four principal steps in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of integrating a sample into a laboratory’s system. This step entails verifying the proper sealing and shipping of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing any further data entry not available via an electronic chain of custody system.
Screening serves as the preliminary evaluation for drugs of abuse. Though Screening offers a cost-effective method to eliminate drug usage in most samples, a positive screen requires confirmation to be considered valid in court. Samples showing presumptive positivity in Screening necessitate secondary confirmation.
If during the Screening stage a sample is presumptively positive, additional hair is extracted from the primary specimen and prepared for Extraction. In this phase, drugs are removed from hair at a substantially reduced concentration compared to other methods (such as urine or oral fluid), underscoring the higher complexity of performing hair drug screening.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples with presumptive positivity are washed if necessary. The entire laboratory procedure from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
