Hair testing is acclaimed as an effective method for identifying drug and alcohol consumption. Hair captures long-term substance history by embedding biomarkers within the strands as they grow. When sourced near the scalp, hair can offer a detection timeline of up to three months for drugs and alcohol. It is easy to gather, relatively tamper-resistant, and straightforward to send.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (equivalent in size to a #2 pencil) near the scalp ensures an optimal 100mg sample for testing. For EtG, additional requests, or panels exceeding 10, 150mg is advisable. Using a jeweler’s scale for weighing the specimen is suggested. In cases where scalp hair isn't available, a comparable amount of body hair can be used. "Head hair" pertains solely to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
Laboratory processing of drug tests encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial integration into the lab system. This step involves confirming proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and addressing any necessary data entry absent from an electronic chain of custody system.
Screening is a preliminary evaluation for substances of abuse. While this method cost-effectively excludes drug use for most samples, court admissibility requires confirmation of a positive screening. Samples that test presumptive positive during Screening require further verification.
With a Screening presumptive positive, additional hair is prepared for Extraction. This stage involves extracting drugs from hair at concentrations significantly lower than those in alternative methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Any confirmed positive Screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are washed as necessary before confirmation. The whole procedure, spanning Accessioning to Confirmation, aligns with both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests", the analysis actually targets the hair strand, not the follicle beneath the scalp.
