Hair drug testing has gained recognition as a robust method for identifying the presence of drugs and alcohol. Hair captures a long-term record of substance use by incorporating biomarkers into the fibers of the growing hair. When taken near the scalp, hair can reveal drug and alcohol use for approximately a 90-day period. Hair collection is straightforward, offers resistance to tampering, and is easy to transport.
A sample measuring 1.5 inches in length, consisting of about 200 hair strands (similar in size to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is ideal for both initial screening and confirmatory testing. For EtG, additional procedures, and/or tests beyond 10 panels, a sample weight of 150mg is advised. We suggest using a jeweler's scale for accurate measurement. In situations where scalp hair cannot be obtained, an equivalent quantity of body hair can be used. References to head hair pertain specifically to scalp hair. Body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory procedure for processing a drug test result includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This step confirms proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any extra data entry that may not be included in an electronic chain of custody system.
Screening serves as an initial, rapid assessment for drug presence. Although Screening is a cost-efficient strategy to eliminate drug usage in most samples, a positive result must be verified to be acceptable in legal proceedings. Samples that test positive during Screening necessitate further confirmation.
Upon a positive result at the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. At this stage, drugs are retrieved from hair in lesser concentrations compared to other methods (such as urine or oral fluid), explaining why hair drug screening poses the greatest challenge in terms of methodology.
Confirmation of any positive result from screening is performed through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positives are cleansed prior to confirmation when required. The complete laboratory sequence from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
