Recognized as a robust instrument, hair testing efficiently identifies drug and alcohol consumption. By embedding biomarkers within the strands of growing hair, it offers a prolonged history of substance use. When sourced near the scalp, hair has the potential to disclose drug and alcohol usage for up to three months. Collection is straightforward, posing challenges to tampering while ensuring easy shipment.
A segment of hair measuring 1.5 inches, consisting of approximately 200 strands (similar in girth to a #2 pencil), gathered closest to the scalp, yields 100mg—optimal for screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale for specimen measuring is suggested. Should scalp hair be inaccessible, a comparable quantity of body hair is acceptable. By head hair, we specifically mean scalp hair. Body hair, however, encompasses all other types (e.g., facial, axillary).
Process Overview
The key phases in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the lab’s system, ensuring it’s correctly sealed and transported, assigning a LAN (Laboratory Accessioning Number), and completing any extra data entry absent from electronic custody records.
Screening is a preliminary rapid assessment for drugs of abuse. While it is cost-effective, a positive screen must be confirmed for legal acceptance. Samples that yield a presumptive positive result during Screening necessitate secondary confirmation.
Should a sample show presumptive positivity during Screening, further hair from the specimen is extracted for Extraction. Drugs are removed from hair at an exceptionally low concentration compared to other methodologies (like urine or oral fluids), rendering hair drug screening the most challenging to implement.
Confirmation of any positive outcome after screening occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing prior to confirmation if needed. The full laboratory procedure from Accessioning through Confirmation is overseen under both CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation.
