Hair testing has emerged as an effective instrument for identifying drug and alcohol consumption. Hair archives a lengthy history by embedding biomarkers within the fibers of the growing hair. A sample taken near the scalp can reveal substance use history spanning nearly three months. The process of collecting hair is straightforward, moderately resistant to tampering, and simple to transport.
A 1.5-inch sample comprising roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp will yield 100mg of hair—optimal for both screening and confirmation processes. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. Should scalp hair be insufficient, a comparable amount of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The laboratory procedures for processing a drug test result encompass four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's framework. This encompasses ensuring the sample's seal and proper shipment, assigning it a LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an electronic custody chain.
Screening involves a rapid preliminary drug usage assessment. It is an economical way to rule out drug usage for most samples, but a positive screen necessitates confirmation for legal proceedings. Samples with a presumptive positive Screening result require further confirmation.
Presumptive positives in the Screening phase lead to more hair being extracted from the initial sample to prepare for Extraction. During Extraction, drugs are separated from the hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique.
Confirmed positive screen results undergo verification via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples showing presumptive positives are thoroughly washed prior to confirmation. The entire procedure, from Accessioning to Confirmation, complies with the CAP (College of American Pathologists) Hair criteria and aligns with ISO / IEC 17025 standards.
