Hair analysis is now viewed as an effective instrument for identifying alcohol and drug consumption. Hair retains a detailed record of drug and alcohol markers within the fibers of the growing strands. When taken from near the scalp, it can provide an alcohol and drug detection record spanning roughly 3 months. This type of sample is easy to gather, tough to tamper with, and convenient to send.
A sample of 1.5 inches, comprising around 200 hair strands (equivalent in size to a #2 pencil) nearest to the scalp, yields 100mg—ideal for screening and confirming purposes. For EtG, additional tests, or more than 10 panels, 150mg is advised. We suggest using a jeweler’s scale for accuracy. If head hair isn't accessible, collecting a comparable amount of body hair is viable. When referencing head hair, it pertains only to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug test result processing in laboratories involves four sequential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes initially processing a sample into the lab's system, ensuring the sample was sealed and transported correctly, assigning it a random LAN (Laboratory Accessioning Number), and filling in any additional information not provided by an electronic chain of custody system.
Screening performs an initial drug-of-abuse check. Although cost-effective for negating drug use in most cases, a confirmed screen is essential for legal admissibility. Samples showing initial positive results in Screening necessitate further confirmation.
Should a Screening stage return positive, more hair is sourced from the original sample for Extraction. This phase involves extracting drugs from the hair at lower concentrations than other tests (e.g., urine or oral fluid), making hair drug screening particularly challenging.
GC/MS, GC/MS/MS, or LC/MS/MS confirms any positive screening outcomes. Presumptive positive samples receive a necessary wash before confirmation. The laboratory process under CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation is thoroughly reviewed from Accessioning to Confirmation.

Note: Despite being often termed "hair follicle tests", the actual analysis is of the hair strand, not the subscalp follicle.
