Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug markers by securing them within the strands. When obtained near the scalp, hair can reveal a detection period extending up to roughly three months for both alcohol and substances. Hair is straightforward to gather, challenging to tamper with, and simple to send.
A segment measuring 1.5 inches comprising roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg, the optimal sample for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen weight of 150mg is suggested. Utilizing a jeweler’s scale for weighing the specimen is advised. In the absence of scalp hair, a similar quantity of body hair is collectable. "Head hair" denotes solely scalp hair. "Body hair" encompasses all other types (such as facial and axillary).
Process Overview
The laboratory stages for assessing a drug test sample encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial stage of processing a sample within a laboratory’s system. This involves ensuring the sample was sealed and dispatched correctly, attributing a random LAN (Laboratory Accessioning Number), and filling in any supplementary data missing from an electronic chain of custody system.
Screening entails an opening rapid examination for abusive substances. While Screening offers a cost-efficient path to dismiss drug usage in most samples, a positive screen must undergo confirmation to be permissible in court. Samples indicated as presumptively positive in Screening necessitate additional confirmation.
For samples flagged presumptively positive in Screening, more hair is extracted from the original specimen for preparation in Extraction. This step involves extracting drugs from hair at far lower concentrations than alternative methods (such as urine or oral fluid), making hair drug screening notably complex to execute.
Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples undergo washing before confirmation as needed. The full laboratory cycle from Accessioning to Confirmation is supervised under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation standards.
