The use of hair testing has gained recognition as a robust method for identifying drug and alcohol consumption. Hair captures a long-term account of alcohol and drug exposure by embedding biomarkers within the fiber of developing hair strands. Obtained near the scalp, hair offers a detection period that spans roughly up to three months for alcohol and other substances. It is straightforward to gather, difficult to tamper with, and facilitates easy transportation.
A 1.5-inch hair sample comprising around 200 strands (equivalent to the thickness of a #2 pencil) close to the scalp supplies 100mg of hair, which is the preferred sample size for analysis and authentication. For EtG and tests exceeding 10 panels, a 150mg specimen is suggested. Utilizing a jeweler’s scale for weighing the specimen is recommended. In cases where scalp hair is unavailable, a corresponding quantity of body hair can be used. The term head hair exclusively denotes scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).
Procedure Overview
The laboratory processing of a drug test outcome includes four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial integration of a sample into a laboratory's database. This phase involves ensuring the sample was properly sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and completing any required data entry that is not captured by an electronic chain of custody system.
Screening offers an initial rapid evaluation for the presence of drugs. Although Screening is an economical method for excluding drug presence in most samples, a positive screening result necessitates confirmation to be valid in legal proceedings. Samples deemed presumptively positive during Screening must undergo secondary confirmation.
If a sample is determined to be presumptively positive at the Screening phase, additional hair is drawn from the original sample for Extraction preparation. Here, drugs are separated from the hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), underscoring why hair drug screening is the most challenging method to execute.
Confirmation of any positive screening results is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo necessary washing. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes evaluation in compliance with both the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 accreditation standards.
