Hair examinations have emerged as an effective means for identifying alcohol and drug consumption. Hair retains a lengthy history of substance use by encapsulating indicators within the strands of the developing hair. When extracted near the scalp, hair can offer roughly a 3-month period for identifying substances such as alcohol and drugs. Hair is easy to collect, less vulnerable to tampering, and simple to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (around the thickness of a #2 pencil) near the scalp will yield 100mg of hair, suitable for both preliminary screening and verification. For EtG, additional tests, and/or tests exceeding 10 types, a specimen quantity of 150mg is advised. Utilization of a jeweler’s scale is suggested for weighing the sample. In the absence of scalp hair, a similar amount of body hair can suffice. By head hair, we mean solely scalp hair, whereas body hair encompasses all other categories (facial, axillary, etc.).
Process Overview
The laboratory procedure for drug test analysis comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory system. This step involves confirming that the sample was correctly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any required data entry missing from an electronic custody chain system.
Screening involves an initial broad assessment for substances of abuse. While Screening is an affordable method to dismiss substance usage in the majority of samples, a positive screening outcome requires validation for court acceptability. Samples yielding presumptive positives in Screening necessitate additional confirmation.
Should a sample register as presumptively positive during Screening, additional hair is taken from the initial sample and prepared for Extraction. During this phase, substances are withdrawn from hair at significantly lower densities than alternate methodologies (e.g., urine or oral fluid), which reasons hair drug assessment as the most challenging to conduct.
Verification of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All initial positive samples undergo washing prior to necessary confirmation. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair categorization and the accreditation of ISO / IEC 17025 standards.
