Hair analysis has grown to be regarded as a decisive method for identifying drug and alcohol consumption. Hair retains a prolonged record of substances like alcohol and drugs by embedding biomarkers in the fibers as hair grows. Hair collected near the scalp can offer up to an estimated 3-month detection timeline for alcohol and drugs. Collection of hair is straightforward, somewhat hard to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and validation. For EtG, additional testing, and/or more than 10 panels, a specimen amount of 150mg is recommended. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair cannot be obtained, equivalent body hair may be used. When mentioning head hair, we mean scalp hair only. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four principal steps involved in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the primary handling of a sample in a lab's system. This step ensures the sample is sealed and sent correctly, allocates a random LAN (Laboratory Accessioning Number), and completes any missing data entry that isn’t provided by an electronic chain of custody system.
Screening conducts an initial rapid check for drugs. While Screening offers an economical method to rule out drug use in most samples, a positive screen must be validated to be court-admissible. Any samples that are deemed positive in Screening demand a secondary confirmation.
If a sample is presumed positive in the Screening phase, additional hair is taken from the initial specimen to prepare for Extraction. During this phase, drugs are extracted from hair at concentrations significantly lower than other methodologies (e.g., urine or oral fluid), thus making hair drug analysis the most challenging to execute.
Confirmation of any positive results from Screening employs GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples undergo washing before confirmation, if necessary. The complete process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation and meets the accreditation to ISO / IEC 17025 standards.
