Acknowledged as a significant asset in detecting drug and alcohol consumption, hair analysis reveals an extended history by holding onto biomarkers within the hair's complex structure. A sample taken directly from the scalp provides a detection window reaching up to three months for alcohol and drugs. The collection of hair is straightforward, resistant to tampering, and convenient to transport.
Collecting a 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp yields 100mg, an optimal sample for both screening and verification. For EtG, additional assessments, and panels exceeding ten in number, 150mg of hair is advised. It's best to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, a corresponding quantity of body hair can be used. When indicating head hair, it pertains solely to scalp hair. All other hair types fall under body hair (such as facial, axillary, etc.).
Process Overview
The core steps in the lab processing of drug test results encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample processing into a lab's database, ensuring the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry missing from the electronic chain of custody.
Screening serves as a preliminary rapid check for potential drug misuse. Though Screening is a cost-effective method to rule out drug usage in most cases, any positive screening result requires confirmation to stand in a legal context. Samples indicating a presumptive positive in Screening demand further confirmation.
In case a sample shows a preliminary positive in Screening, additional hair is extracted from the initial batch and readied for Extraction. At this stage, drugs are isolated from hair at lower concentrations than in other methods (e.g., urine or saliva), substantiating hair analysis as the most intricate procedure to execute.
Confirmation of any positive screening outcomes follows using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating possible positivity undergo a washing step before confirmation as necessary. The entire process, from Accessioning to Confirmation, is scrutinized under the guidelines of both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.
