Hair testing is widely acknowledged as an effective method for identifying substance use, including drugs and alcohol. By capturing biomarkers, hair strands offer a comprehensive timeline of substance consumption. When samples are taken near the scalp, they can reveal a detection period of up to 3 months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient for transport.
A sample measuring 1.5 inches with roughly 200 hair strands (similar to a #2 pencil's diameter) procures 100mg of hair, perfect for screening and validation. For tests exceeding 10 panels, or including EtG and add-ons, a 150mg sample is advised. Utilizing a jeweler's scale to measure the sample is suggested. If scalp hair isn't available, a similar quantity of body hair can be utilized. References to head hair relate strictly to scalp hair. All other hair (e.g., facial, axillary) is considered body hair.
Process Overview
The laboratory processing for drug test analysis encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial integration of a sample into the lab's system. This step checks the secure sealing and correct shipment of the sample, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any necessary data input lacking from an electronic chain of custody system.
Screening offers a preliminary check for drug traces. Despite being a cost-efficient approach to mostly exclude drug usage, any screen yielding a positive result must be corroborated for legal acceptability. Presumptive positive results from Screening necessitate further confirmation.
When a sample tests as presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. This stage involves extracting drugs from hair at significantly lower concentrations in comparison to other methods like urine or oral fluid, contributing to hair testing's complexity.
GC/MS, GC/MS/MS, or LC/MS/MS procedures validate any positive Screening results. Presumptive positive samples undergo washing pre-confirmation if necessary. The full lab procedure from Accessioning through Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
