Hair analysis is becoming recognized as an essential method for detecting substance and alcohol consumption. Hair maintains a prolonged record of substances by embedding biomarkers within the strands as they grow. When cut near the scalp, hair may offer a detection period of up to around 90 days for both alcohol and drugs. It is straightforward to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 strands (akin to the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the preferred sample size for testing and verification. For EtG, additional checks, and/or analyses exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler’s scale for weighing. If head hair is not available, a similar volume of body hair may be utilized. When mentioning head hair, it pertains only to the scalp hair. Body hair encompasses other hair types (such as facial, axillary, etc.).
Process Overview
The principal steps in processing a sample for a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially handling a sample into a lab’s database. This process verifies that the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any pending data entry not completed via an electronic chain of custody procedure.
Screening offers an initial rapid evaluation for drug usage. Although Screening serves as an economical way to negate drug use for most samples, a positive result must be verified for legal acceptability. Any samples with a potential positive in Screening require an additional confirmation process.
If the Screening phase indicates a possible positive result, additional hair is retrieved from the primary sample and set for Extraction. In this phase, substances are eliminated from the hair at significantly lower concentrations than other methods (e.g., urine or saliva), making hair drug screening among the most challenging methodologies.
Confirmation of any positive findings from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples considered positive are washed before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation undergoes validation under CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
