Utilizing hair testing has emerged as an effective method for identifying the consumption of drugs and alcohol. Hair captures a prolonged timeline of alcohol and other substances by embedding biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair offers up to a three-month detection timeframe for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.
A sample measuring 1.5 inches comprising roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp can yield 100mg of hair, which serves as the optimal sample size for both screening and confirmation processes. For EtG, additional assessments, and/or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest using a jeweler’s scale for specimen measurement. In the absence of scalp hair, a comparable amount of body hair can be obtained. When mentioning head hair, it references only scalp hair. Body hair encompasses all other forms of hair (facial, axillary, etc.).
Process Overview
Laboratory processing of drug test outcomes comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary processing of a sample within a laboratory’s framework. This stage verifies that the sample has been correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not accommodated by an electronic chain of custody system.
Screening offers an initial, rapid examination for substances of misuse. Screening serves as an economical means to dismiss drug usage for most samples, yet a confirmed screen is essential for court admissibility. Samples that are preliminarily positive in Screening necessitate a secondary confirmation.
Should a sample yield a presumptive positive in the Screening stage, additional hair is extracted from the initial specimen for preparation during Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation for any positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing prior to confirmation if required. The entire laboratory cycle from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and the accreditation of ISO / IEC 17025 standards.
