Hair testing is recognized as a significant method for identifying drug and alcohol consumption. Hair offers an extensive history of alcohol and drugs by encapsulating biomarkers within the structure of the growing hair shaft. When taken near the scalp, hair can reveal up to a 3-month timeframe for detecting alcohol and drugs. Collecting hair is straightforward, fairly resistant to tampering, and convenient for shipping.
A sample measuring 1.5 inches of around 200 hair strands (equivalent to the thickness of a #2 pencil) taken nearest to the scalp will yield 100mg of hair, which is the preferred sample size for analysis. For EtG evaluations, add-ons, or assessments exceeding 10 panels, 150mg of the sample is advised. It is suggested to use a jeweler's scale for weighing the sample. If scalp hair is not present, a proportional amount of body hair can be used. 'Head hair' refers specifically to scalp hair, whereas 'body hair' encompasses other hair types (facial, axillary, etc.).
Process Overview
The core steps in the lab processing of a drug testing result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial integration of a sample into the lab's system. This process verifies that the sample was sealed and delivered properly, assigns a unique LAN (Laboratory Accessioning Number), and completes any further data input not covered by an electronic chain of custody process.
Screening involves a preliminary rapid assessment for substances of abuse. While Screening offers an economical means to exclude drug usage in most samples, any positive findings must be confirmed for court acceptability. All samples showing presumptive positives during Screening must undergo a secondary confirmation.
When a sample yields a presumptive positive result at the Screening stage, additional hair is drawn from the original sample and prepped for Extraction. During Extraction, substances are isolated from hair at a substantially lower concentration than other methods (such as urine or oral fluid), which is why hair drug testing is considered the most challenging method to execute.
Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation, as necessary. The complete laboratory procedure from Accessioning to Confirmation is overseen both under the CAP (College of American Pathologists) Hair criteria and the compliance with ISO / IEC 17025 standards.
