Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug intake by encasing biomarkers within the strands as they grow. When sampled near the scalp, hair can indicate usage within up to approximately a 90-day timeframe for alcohol and other substances. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
Sampling a 1.5-inch segment of around 200 hairs (comparable to the thickness of a #2 pencil) near the scalp yields about 100mg, which is optimal for testing and reconfirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale for weighing the specimen is suggested. In cases where scalp hair is unavailable, a similar quantity of body hair is acceptable. Head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The processing of a drug test result in the laboratory comprises four major phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample undergoes initial processing within a laboratory’s system. This phase ensures the sample is sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any other data entry not covered by an electronic chain of custody system.
Screening involves a preliminary check for substances of abuse. While it is an economical means to dismiss drug usage in most samples, a positive screen needs corroboration to hold up in legal proceedings. Presumptively positive samples from Screening necessitate further verification.
Should a sample test presumptively positive during Screening, more hair is taken from the initial batch and readied for Extraction. This phase involves extracting substances from hair in substantially lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging methodology to execute.
Positive screening outcomes are confirmed via GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo cleansing before confirmation as appropriate. The entire lab procedure from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
