Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair serves as a repository for long-term records of alcohol and drug exposure by trapping biomarkers within the strands of hair as they grow. If taken from near the scalp, it can reveal drug and alcohol presence for a window of up to 3 months. Hair is straightforward to gather, relatively challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches in length containing around 200 hair strands (comparable to a #2 pencil) taken nearest to the scalp will yield 100mg of hair, which is perfect for conducting screening and verification. For EtG, additional tests, and examinations exceeding 10 panels, a specimen weighing 150mg is advised. It's advisable to measure the specimen with a jeweler's scale. In the absence of scalp hair, a comparable quantity of body hair can be used. Head hair indicates scalp hair exclusively. Body hair includes other hair types (facial, axillary, etc.).
Process Overview
The laboratory examination of a drug test result encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within a laboratory's framework. This step validates that the sample is sealed and properly dispatched, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any supplementary data input absent in an electronic chain of custody system.
Screening consists of a preliminary expedited assessment for substances of abuse. Although Screening is economical for eliminating drug usage in most samples, a positive outcome requires confirmation for courtroom acceptability. Any samples allegedly positive in Screening necessitate further verification.
Should a sample initially test positive during Screening, more hair from the original specimen is prepared for Extraction. In Extraction, drugs are isolated from hair at concentrations notably lower than those in other methods (e.g., urine or oral fluid), making hair drug testing particularly challenging.
Verification of any positive Screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicated as positive are pre-washed as necessary before confirmation. Every step from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and with ISO / IEC 17025 accreditation.
