Hair analysis serves as an effective method for identifying substance and alcohol consumption. By capturing biomarkers within the strands, hair offers a prolonged record of drug and alcohol use. When sourced near the scalp, hair reveals a detection window of up to roughly 3 months for both drugs and alcohol. Hair collection is straightforward, hard to tamper with, and convenient for transportation.
A close-to-the-scalp 1.5-inch sample with approximately 200 hair strands (equivalent to a #2 pencil's diameter) yields 100mg, which is the preferred quantity for both screening and confirmation. For EtG, test extensions, and evaluations beyond 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for weighing the specimen is recommended. In the absence of scalp hair, a comparable quantity of body hair can be gathered. Head hair refers exclusively to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
Laboratory handling of a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial integration of a sample into the laboratory system. This phase involves confirming that the sample was properly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent from the electronic chain of custody system.
Screening entails an initial brief evaluation for substances of abuse. Although Screening is a budget-friendly means to exclude drug usage for most samples, a positive result must be verified to be legally permissible. Samples that test preliminary positive during Screening necessitate further confirmation.
Should a sample yield a preliminary positive result at the Screening stage, more hair from the initial collection is utilized for Extraction. In this phase, substances are withdrawn from hair at significantly lower levels than other methods (e.g., urine or oral fluid), which is why performing hair drug screening is particularly challenging.
Verification of any positive Screening result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that indicate a positive result are cleansed before Confirmation if needed. The complete laboratory procedure, from Accessioning through Confirmation, is assessed following both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
