Regarded as a formidable instrument for identifying substance and liquor consumption, hair testing offers a prolonged historical record of substance use by capturing biomarkers within the growing hair's fibers. Collected near the scalp, hair can provide roughly a 90-day period of detection for substances. The process of collecting hair is straightforward, difficult to tamper with, and easy to transport.
A 1.5-inch portion encompassing about 200 hair strands (comparable to a #2 pencil) closest to the scalp delivers 100mg of hair, which is the optimal sample amount for both testing and verification. For EtG, supplementary tests, and/or screenings over 10 panels, it is advised to collect 150mg of the sample. Utilizing a jeweler’s scale for weighing the sample is recommended. If there's an absence of scalp hair, equivalent body hair can be utilized. References to head hair specifically mean scalp hair only whereas body hair covers other types (facial, axillary, etc.).
Process Overview
The drug test result processing within a lab involves four chief steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes initial sample incorporation into the laboratory's system, ensuring proper seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry beyond an electronic chain of custody system.
Screening performs an initial overview to check for drug abuse. Though cost-effective for ruling out drug use in many samples, positive screenings can't be court-admitted without confirmation. Samples testing presumptively positive in Screening require further confirmation.
Should a sample be presumptively positive during Screening, additional strands are extracted from the initial specimen for Extraction. Here, substances are removed from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), marking hair drug screening as the most challenging process.
Confirming any positive screening is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptively positive samples undergo necessary washing before confirmation. The comprehensive lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Notice: Routinely termed as "hair follicle tests", in reality, the examination targets the hair strand rather than the follicle beneath the scalp.
