Utilizing hair evaluations has emerged as a significant method for identifying alcohol and drug consumption. Hair offers an extended historical account of alcohol and substance use by encapsulating biomarkers within the strands of developing hair. When taken near the scalp, hair can present a detection window of nearly three months for alcohol and substances. Hair collection is straightforward, relatively resistant to tampering, and easy for transportation.
A 1.5-inch section comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) close to the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, additional analyses, and tests beyond 10 panels, 150mg of the sample is advised. Using a jeweler's scale to weigh the sample is recommended. If scalp hair cannot be obtained, a comparable quantity of body hair can be gathered. References to head hair denote only scalp hair. Body hair pertains to all other hair types (such as facial, axillary, etc.).
Process Overview
Key stages in laboratory drug test processing encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of preliminarily entering a specimen into the laboratory system. This encompasses ensuring the sample was adequately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing necessary additional data entry not supplied by an electronic chain of custody system.
Screening involves a preliminary, swift test for substance abuse. Although Screening is a cost-effective approach to exclude drug use in most specimens, a positive finding requires confirmation for legal admissibility. Samples indicating presumptive positives in Screening need a secondary affirmation.
If initial Screening suggests a presumptive positive, more hair is extracted from the original sample and readied for Extraction. In this stage, substances are isolated from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to conduct.
Confirmation of any screening positive is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a cleanse prior to confirmation, if necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation following ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly called "hair follicle tests," the assessment targets the hair strand itself, rather than the follicle under the scalp.
