Hair testing emerges as an effective instrument for identifying drug and alcohol usage. Hair captures a long-term history of alcohol and various drugs by embedding biomarkers within the fibers of the hair's growth. When gathered close to the scalp, hair can deliver a detection window of up to roughly 3 months for alcohol and additional drugs. Hair collection is easy, relatively resistant to tampering, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (similar to the size of a #2 pencil) closest to the scalp offers 100mg of hair, which is the optimal sample for screening and confirmation. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair is not present, an equivalent amount of body hair can be gathered. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other hair variants (such as facial, axillary, etc.).
Process Overview
The laboratory process of drug test result analysis encompasses four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of introducing a sample into a laboratory’s system. This step includes confirming that the sample was securely sealed and properly shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not furnished by an electronic chain of custody system.
Screening consists of an initial rapid drug check. While Screening is an economical method to dismiss drug usage in most samples, a positive screen necessitates confirmation to be accepted in court. Samples deemed presumptively positive in Screening demand subsequent confirmation.
If a sample returns presumptively positive in the Screening phase, extra hair is extracted from the initial sample for preparation in the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug screening a challenging method to execute.
GC/MS, GC/MS/MS, or LC/MS/MS are employed for confirming any positive screening outcomes. All samples deemed presumptively positive are cleansed prior to confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
Note: Frequently called "hair follicle tests", the test itself examines the hair strand rather than the follicle beneath the scalp.
