Hair testing has emerged as an effective means for identifying the use of drugs and alcohol. Hair retains a long-term history of substances by encapsulating biomarkers within the strands as they grow. When hair samples are taken from near the scalp, they offer as much as a three-month detection period for substances. Collecting hair is straightforward, moderately resistant to tampering, and straightforward to transport.
Collecting a 1.5-inch segment of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For tests involving EtG, additional analyses, or more than 10-panel screens, 150mg of the sample is suggested. Utilizing a jeweler's scale for weighing the sample is advisable. If scalp hair cannot be obtained, a comparable amount of body hair may be gathered. References to head hair pertain strictly to scalp hair, whereas body hair refers to other hair categories (facial, axillary, etc.).
Process Overview
There are four primary phases in the laboratory validation of a drug analysis: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial registration of a sample into the lab's database. This step verifies that the sample was correctly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entries not provided by an electronic chain of custody system.
Screening is an initial evaluation for drugs of abuse. Although Screening is an economical way to exclude drug usage in most samples, any positive findings must be validated to be applicable in court. Samples that test positive during Screening require further confirmation.
If results are positive during Screening, more hair is extracted from the initial sample and readied for Extraction. This phase involves retrieving drugs from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), hence making hair drug screening the most intricate methodology to carry out.
Confirmation of positive screening findings is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All positive samples undergo washing prior to confirmation if necessary. The complete laboratory procedure from Accessioning through to Confirmation is overseen under the CAP (College of American Pathologists) Hair classification and compliant with ISO / IEC 17025 criteria.
