Hair testing has gained recognition as a robust method for identifying drug and alcohol consumption. Hair stores a long-term record of alcohol and drugs by encasing biomarkers within its strands. When taken from the scalp, it can offer a detection period of up to roughly 90 days for various substances. It is easy to collect, challenging to tamper with, and straightforward to transport.
A sample of 1.5 inches, consisting of approximately 200 hair strands (comparable to a #2 pencil in size) nearest to the scalp, yields 100mg, which is the preferred amount for initial and confirmatory testing. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale to measure the specimen is recommended. Should scalp hair be inaccessible, an equivalent volume of body hair can be used. By head hair, we specifically refer to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
In the processing of a drug test result, four key stages are included: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of integrating a sample into a lab's operations. This stage checks that the sample was sealed and transported correctly, allocates a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry not covered by an electronic chain of custody system.
Screening is an expedited preliminary analysis for drugs of abuse. Although Screening serves as a cost-effective approach to negate drug presence in the majority of samples, any positive screening must be verified for court admission. Samples showing presumptive positivity in Screening necessitate further confirmation.
If a specimen produces a presumptive positive from the Screening, further samples from the initial collection are prepared for Extraction. In this process, drugs are derived from hair in much lower concentrations than other testing methods (such as urine or oral fluids), which makes hair drug screening the most challenging methodology to execute.
GC/MS, GC/MS/MS, or LC/MS/MS methods carry out the Confirmation of any positive screening outcomes. Before confirmation, all presumptive positive samples are washed when necessary. The comprehensive laboratory procedure from Accessioning through Confirmation undergoes evaluation under the scrutiny of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
