Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair specimen analysis is now recognized as an effective method for detecting drug and alcohol intake. The hair retains a prolonged record of alcohol and drug ingestion by encapsulating biomarkers within the growing hair fiber. By obtaining hair samples near the scalp, the detection period for substances like alcohol can extend to roughly three months. The collection of hair is straightforward, tampering is relatively challenging, and transport is convenient.
A hair sample of 1.5 inches, comprising approximately 200 strands of hair (similar in thickness to a #2 pencil) near the scalp, yields 100mg, the optimal quantity for both screening and confirmation tests. For EtG, additional tests, or screenings beyond 10 panels, 150mg is suggested. We advise measuring the sample on a jeweler’s scale. If scalp hair is scarce, a comparable quantity of body hair may be used. Scalp hair refers to the hair on the head exclusively, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The lab process for processing a drug research outcome comprises four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step in which a sample enters the lab's system. This step checks if the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes required data entry not covered by an electronic chain of custody system.
Screening involves a preliminary assessment for substances of misuse. While Screening is a cost-savvy approach to eliminate drug intake for most samples, any positive findings require further confirmation to be acceptable in legal situations. Samples that show a presumptive positive in Screening mandate additional confirmation.
Should a sample show a presumptive positive in the Screening phase, further hair is taken from the original sample for Extraction. This phase involves drug removal from hair at a significantly lower concentration than other techniques (e.g., urine or oral fluid), hence hair drug testing is the most complex method to execute.
To affirm any positive outcome from screening, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples presumed positive are cleansed before confirmation as required. The complete laboratory procedure, from Accessioning to Confirmation, is examined both under the CAP (College of American Pathologists) Hair designation and in adherence to ISO / IEC 17025 standards.
