Hair assessment has become acknowledged as a robust instrument for identifying alcohol and drug consumption. Hair retains a lasting record of various substances by embedding biomarkers within the fibers of the growing strands. When cut near the scalp, it offers a detection period of nearly 3 months for alcohol and drugs. Collection is straightforward, it's somewhat resistant to tampering, and shipping is uncomplicated.
A segment measuring 1.5 inches, consisting of roughly 200 hair strands (similar to a #2 pencil in size) from the scalp provides 100mg of hair, an optimal amount for both screening and confirmation. For additional analyses, such as EtG or tests exceeding 10 panels, 150mg of the sample is advisable. It’s best to weigh the sample with a jeweler’s scale. If head hair is not accessible, an equivalent volume of body hair may be used. In terms of head hair, this refers solely to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug test result processing in the laboratory encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the introductory inclusion of a sample into a lab’s system. This step involves confirming the sample is properly sealed and shipped, assigning it a unique LAN (Laboratory Accessioning Number), and fulfilling any extra data entry lacking in an electronic chain of custody system.
Screening offers a preliminary rapid check for substances of abuse. While it is a cost-efficient method to discard drug use for most samples, a positive result in Screening requires confirmation to be deemed valid in a courtroom setting. Samples yielding presumptively positive results in Screening necessitate a subsequent confirmation.
Should a sample be presumed positive at the Screening phase, further hair is extracted from the initial collection and prepared for Extraction. At this stage, drugs are isolated from the hair at notably lower concentrations than alternative techniques (e.g., urine or oral fluid), hence making hair drug screening a methodologically challenging process.
Verification of any positive Screening result is achieved through GC/MS, GC/MS/MS or LC/MS/MS. All samples indicating presumptive positivity undergo washing before confirmation when necessary. The comprehensive lab process, from Accessioning to Confirmation, is evaluated according to both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 accreditation.

Limitations:
Note: Despite being commonly termed "hair follicle tests", the analysis is conducted on the hair strand rather than on the follicle below the scalp.
