Hair examination has emerged as a potent method for detecting the consumption of drugs and alcohol. The hair offers an extended timeline of alcohol and other substances by ensnaring biomarkers within the strands as they grow. When procured near the scalp, hair can indicate alcohol and other drugs usage over a span reaching up to three months. Hair is straightforward to collect, relatively tough to tamper with, and simple to transport.
A 1.5-inch segment comprising roughly 200 hair strands (equivalent to a #2 pencil thickness) from near the scalp yields 100mg of hair, the perfect sample size for both screening and confirmation assessments. For EtG, additional testing, and/or panels exceeding ten, 150mg of the sample is advised. Utilizing a jeweler’s scale is recommended for weighing the sample. If scalp hair cannot be sourced, a comparable amount of body hair can be gathered. When the text mentions head hair, it is specifically indicating scalp hair. Body hair pertains to any other types of hair (like facial, axillary, etc.).
Process Overview
The primary procedures involved in a laboratory processing a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the foundational processing of a specimen into a laboratory’s framework. This encompasses ensuring that the sample was sealed and conveyed appropriately, affixing a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening renders an initial swift assessment for drugs of abuse. Although Screening is an economical approach to exclude drug use in most samples, a positive screen requires confirmation to be permissible in court. Any samples that test presumptively positive in Screening necessitate a follow-up confirmation.
If a sample produces a presumptive positive result in the Screening phase, more hair is drawn from the original sample to prepare for Extraction. At this stage, drugs are derived from hair at much lower concentrations than is typical with other methodologies (like urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation, as necessary. The comprehensive laboratory operation from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the acknowledgment to ISO / IEC 17025 standards.
