Hair testing is widely acknowledged as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair offers a long-term record of alcohol and other drug use. When collected near the scalp, hair can reveal approximately a 3-month period of alcohol and drug detection. Hair samples are easy to collect, not easily altered, and simple to mail.
A 1.5-inch sample consisting of roughly 200 strands of hair (approximately the width of a #2 pencil) closest to the scalp is required to provide 100mg of hair, the recommended amount for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, it's advised to use 150mg of the sample. We suggest evaluating the sample using a jeweler's scale. If scalp hair isn't accessible, an equivalent amount of body hair can be collected. When mentioning head hair, we are specifically referring to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
There are four essential steps in the laboratory processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into a lab's system. This step encompasses verification that the sample was sealed and transported correctly, allocation of a random LAN (Laboratory Accessioning Number), and completion of any additional data input not covered by an electronic chain of custody protocol.
Screening provides an initial rapid assessment for drugs of abuse. While Screening is a reliable method for disproving drug use on the majority of samples, a positive result needs verification for court admissibility. Any samples that return a positive result in Screening must undergo secondary confirmation.
If a sample receives a presumptive positive in the Screening phase, additional hair is extracted from the original sample for Extraction. In this stage, drugs are isolated from the hair at a much lower concentration than other methods (e.g., urine or oral fluid), highlighting why hair drug screening is considered the most challenging methodology to execute.
Confirmation for any positive Screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing a presumptive positive result are cleansed prior to confirmation as necessary. The complete laboratory process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair acknowledgment and the accreditation to ISO / IEC 17025 criteria.
