Hair testing has emerged as a significant method to detect drug and alcohol consumption. Hair captures biomarkers within its strands, offering a long-term view of substance use. Hair samples taken near the scalp can reveal up to a 3-month period of substance use. It is straightforward to collect, relatively immune to tampering, and easy to transport.
A sample of 1.5 inches, comprising about 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp, provides 100mg of hair, which is optimal for both screening and confirmation tests. For tests involving EtG, add-ons, or exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for specimen weighing. If scalp hair is absent, equivalent body hair may be used. 'Head hair' pertains specifically to scalp hair, while 'body hair' includes all other types (facial, underarm, etc.).
Process Overview
The laboratory procedure for processing a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial sample processing within the laboratory system; this step confirms proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any further data input absent from an electronic chain of custody.
Screening provides a preliminary rapid analysis for commonly abused drugs. Although Screening is a cost-effective means to rule out drug use in most samples, any positive result must undergo Confirmation to be valid in legal settings. Presumed positive samples from Screening necessitate subsequent confirmation.
Upon a presumptive positive result in Screening, additional hair is extracted from the primary specimen for the Extraction phase. Here, drugs are sourced from hair samples at a lower concentration when compared with other testing methods (e.g., urine or saliva), marking hair drug screening as a sophisticated endeavor.
GC/MS, GC/MS/MS, or LC/MS/MS techniques validate any positive screening outcomes. Presumptive positive samples are washed before the final Confirmation if necessary. The comprehensive laboratory process from Accessioning through Confirmation is subjected to a review based on the CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.
