Hair testing is now recognized as a robust method for unveiling drug and alcohol consumption. Hair retains a long-term record of these substances by capturing biomarkers in the growing strand's fibers. When sourced near the scalp, hair can offer a detection period for alcohol and substances extending up to roughly 3 months. Hair collection is straightforward, moderately resistant to tampering, and simple to transport.
A 1.5-inch section of approximately 200 hair strands (similar to a #2 pencil's size) near the scalp yields 100mg of hair, optimal for screening and verification. For EtG, add-ons, and/or panels beyond 10, a specimen of 150mg is advisable. It's suggested to measure the specimen using a jeweler's scale. If scalp hair isn't obtainable, a comparable quantity of body hair can be utilized. The term head hair pertains exclusively to scalp hair. Body hair encompasses all other types (like facial, axillary, etc.).
Process Overview
The primary stages in processing a lab drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into a lab's system. This stage involves confirming the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and filling in any extra data missing from an electronic chain of custody framework.
Screening involves a preliminary rapid check for substance misuse. Screening offers a budget-friendly method to dismiss drug use in most samples; however, a positive find requires confirmation to be court-admissible. Any samples that show a presumptive positive during Screening must undergo further confirmation.
Should a sample test presumptively positive in Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are separated from hair at much lower concentrations compared to other methods (like urine or oral fluids), rendering hair drug screening the most challenging method to execute.
Confirmation for any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before Confirmation as necessary. The complete lab process from Accessioning to Confirmation is audited under CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the analysis targets the hair strand itself, not the follicle beneath the scalp.
