Hair analysis is recognized as an effective approach for identifying drug and alcohol use. It offers a long-term record of substance use by capturing biomarkers within the fibers of the hair strand as it grows. When hair is cut closely to the scalp, it can offer about a 3-month window for detecting alcohol and drugs. It is easy to collect, tough to tamper with, and straightforward to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (comparable to a #2 pencil) near the scalp will yield 100mg of hair, an excellent amount for screening and verification. For tests involving EtG, additional panels, and/or tests exceeding 10 substances, it is advised to collect 150mg. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair cannot be obtained, the same amount of body hair can be utilized. Head hair refers exclusively to scalp hair. Body hair encompasses all other types (including facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the sample’s preliminary integration into the laboratory's system. This process confirms the sample’s proper sealing and dispatch, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry the electronic chain of custody system doesn’t cover.
Screening executes an initial assessment for drugs of abuse. This economical method can rule out drug consumption for the majority of samples, but any positive screening must undergo confirmation for legal admissibility. Samples that screen presumptively positive mandate secondary confirmation.
Should a sample return a presumptive positive result during Screening, additional hair is extracted from the initial sample for the Extraction phase. At this stage, drugs are extracted from hair at a much lower concentration compared to other techniques (such as urine or oral fluid), making hair drug analysis one of the most complex forms of testing.
GC/MS, GC/MS/MS, or LC/MS/MS conducts confirmation for any positive screening outcomes. Prior to confirmation, all presumptive positives undergo washing if necessary. The entire lab process from Accessioning through Confirmation adheres to both CAP (College of American Pathologists) Hair determination and ISO/IEC 17025 standards.
