Hair analyses have gained recognition as an effective approach for identifying drug and alcohol consumption. Hair captures a long-lasting record of substance use by embedding biomarkers within the strands of the hair as it grows. A hair sample taken near the scalp can yield around a 90-day detection period for drugs and alcohol. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.
A sample comprising 1.5 inches of roughly 200 hair strands (comparable to the circumference of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for testing and verification. For EtG and panels beyond 10, 150mg of hair is advisable. We suggest measuring the sample using a jeweler's scale. If scalp hair cannot be obtained, an equal volume of body hair may be used. When we mention head hair, it refers specifically to scalp hair. Body hair encompasses all other hair kinds (facial, axillary, etc.).
Process Overview
The core steps in the laboratory evaluation of a drug testing sample are Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the preliminary handling of a specimen into a lab's records. This step ensures the sample was properly sealed and dispatched, assigns it a random LAN (Laboratory Accessioning Number), and finalizes any extra data input absent from an electronic chain of custody system.
Screening involves an initial, swift assessment for signs of substance misuse. Although Screening provides an economical means to negate drug use in most samples, a positive result necessitates verification to be valid legally. Samples that appear positive during Screening require additional confirmation.
Should a sample test tentatively positive in Screening, additional hair from the initial sample is utilized and made ready for Extraction. Drugs are then retrieved from the hair at significantly lower concentrations compared to other methods (e.g., urine or salivary fluid), which is why hair drug analysis is considered the most challenging method to perform.
Confirmation for a positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing presumptively positive are cleaned before confirmation as necessary. The full laboratory operation from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation criteria.
