Analyzing hair has become recognized as an effective method for detecting drug and alcohol consumption. Hair acts as a long-term record by capturing biomarkers within the fibers of its strands as it grows. When cut close to the scalp, this method can reveal a usage history of up to three months. Hair is simple to gather, challenging to tamper with, and convenient to send.
A 1.5-inch segment of approximately 200 strands (about the thickness of a #2 pencil) close to the scalp yields 100mg of hair, perfect for assessment and verification. For extensive tests like EtG, add-ons, or those exceeding 10 panels, 150mg is advised. We suggest using a jeweler’s scale to weigh the hair. If scalp hair isn't available, an equal quantity of body hair can be collected. Here, “head hair†specifically means scalp hair, while “body hair†includes all other types (beard, armpit, etc.).
Process Overview
The drug testing process in labs consists of four essential steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is introduced into the lab’s system. The process confirms the sample’s sealing and shipment integrity, assigns a random LAN (Laboratory Accessioning Number), and completes any manual data input not captured by digital chain of custody systems.
The Screening phase initiates with a swift examination for illegal drugs. Although Screening is an economical method to eliminate drug presence in most samples, a positive result must be verified to be legally valid. Samples that yield a presumptive positive must undergo additional confirmation.
For any presumptive positive samples, further hair is extracted from the initial sample for the Extraction process. During Extraction, substances are separated from the hair at a substantially lower concentration than other tests (e.g., urine or oral fluids), which is why hair drug testing remains the most challenging method.
GC/MS, GC/MS/MS or LC/MS/MS are used for confirming positive Screening results. Presumptive positive samples are thoroughly cleaned before Confirmation if necessary. Throughout the lab procedure from Accessioning to Confirmation, compliance is ensured with CAP (College of American Pathologists) Hair designation guidelines, and accreditation to ISO / IEC 17025 standards.
