Hair examinations are recognized as an effective instrument for identifying drug and alcohol consumption. Hair retains a prolonged history of substances by encapsulating biomarkers within the strands. When procured near the scalp, it can reveal usage up to a 3-month span. Hair is straightforward to gather, somewhat resistant to tampering, and simple to transport.
A 1.5-inch portion consisting of roughly 200 hair strands (akin to a #2 pencil’s diameter) near the scalp yields 100mg, which is ideal for both preliminary and definitive tests. For EtG, other enhancements, and/or examinations beyond 10 panels, a 150mg quantity is advised. It is recommended to measure the amount using a jeweler's balance. If scalp hair is unobtainable, a comparable volume of body hair is acceptable. Head hair exclusively pertains to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The principal stages in lab processing of a drug screen result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where the sample is incorporated into the lab’s system. This step verifies proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and manages extra data entry absent from an electronic chain of custody system.
Screening provides an initial review for substance misuse. This process is an economical method to exclude drug consumption across most samples; however, if a screen shows a positive, it must be verified to be permissible in court. Any samples that test presumptively positive in Screening necessitate a subsequent confirmation.
If a sample indicates presumptive positivity during Screening, more hair is extracted from the initial sample and readied for Extraction. Here, drugs are pulled from hair at a lower concentration compared to other techniques (e.g., urine or oral fluids), which makes hair drug testing the most complex method to execute.
Confirmation of any positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positives undergo washing prior to confirmation as deemed necessary. From Accessioning to Confirmation, the comprehensive lab process is reviewed under the CAP (College of American Pathologists) Hair designation and accredited to ISO/IEC 17025 standards.
