The utilization of hair testing has emerged as an effective method for identifying drug and alcohol use. Hair strands integrate a longitudinal history of substance consumption by incorporating biomarkers within the fibers of the growing strand. When collected from near the scalp, hair can reveal drug or alcohol use over an approximate duration of three months. The process of collecting hair is straightforward, relatively hard to tamper with, and easy to transport.
A 1.5-inch segment comprised of approximately 200 hair strands (comparable in size to a #2 pencil) closest to the scalp yields 100mg of hair, deemed ideal for both preliminary tests and confirmatory analysis. For those requiring EtG, additional tests, and/or more than 10-panel tests, it is suggested to secure 150mg of the sample. Measuring the specimen with a jeweler’s scale is recommended. In cases where scalp hair is unavailable, a comparable quantity of body hair is acceptable. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types, such as facial and axillary.
Process Overview
The laboratory processing of a drug test result encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the onset of integrating the sample into the laboratory framework. This step verifies the sample's proper sealing and shipment, assigns it a random LAN (Laboratory Accessioning Number), and completes any additional data input absent in an electronic chain of custody system.
Screening entails an initial brief review for substances of abuse. Although Screening is an economical strategy to dismiss drug use in many samples, a positive result necessitates confirmation for legal acceptability. Samples deemed presumptively positive in Screening require verification through further analysis.
In the event of a presumptive positive result during the Screening phase, additional hair is extracted from the original specimen for preparation in the Extraction stage. Here, drugs are retrieved from hair at a lesser concentration compared to other methods (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screening.
Positive results arising from Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples indicating presumptive positivity undergo cleansing prior to confirmation if necessary. The comprehensive laboratory procedure spanning from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and the accreditation consistent with ISO / IEC 17025 standards.
