Hair screening is now widely recognized as an effective method for identifying drug and alcohol consumption. Using hair strands allows for the preservation of drug-related biomarkers within the fibers as the hair grows. Hair obtained near the scalp can indicate drug use spanning up to about three months. Collection is straightforward, with minimal risk of tampering, and it is easy to transport.
Collecting a sample measuring 1.5 inches—comprising approximately 200 hair strands, about the thickness of a #2 pencil—yields 100mg of hair, which is optimal for evaluation and confirmation. For assessments like EtG or those exceeding 10 panels, 150mg is preferable. It's suggested to use a jeweler's scale to measure the sample. In cases where scalp hair is absent, equal amounts of body hair can be used. "Head hair" exclusively refers to scalp hair, while "body hair" encompasses all other types (such as facial and axillary).
Process Overview
The key stages in the processing of a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes its first entry into the laboratory system. This step ensures the sample’s integrity, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data not included in an electronic chain of custody.
The Screening phase performs an initial, swift assessment for drugs of abuse. Although this step is economical and eliminates drug use in most samples, any positive findings must undergo confirmation to be usable in a legal context. All samples flagged as positive during Screening require further confirmation.
If a preliminary positive is found in Screening, additional hair from the original sample is prepped for Extraction. This phase involves extracting drugs from hair at much more diluted concentrations compared to other methods like urine or oral fluid, underscoring the greater complexity of hair drug screening procedures.
Confirmation of positive screens utilizes methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Any sample with a presumptive positive is thoroughly washed before confirmation. The full laboratory protocol—from Accessioning to Confirmation—adheres to the CAP (College of American Pathologists) Hair guidelines and aligns with ISO / IEC 17025 accreditation standards.
