Hair testing is highly regarded as an effective method for identifying drug and alcohol consumption. Hair acts as a long-term record of alcohol and substance use, by embedding biomarkers within the fibers of developing hair strands. When cut close to the scalp, hair can reveal up to a three-month detection period for alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and convenient to transport.
A sample measuring 1.5 inches of approximately 200 hair strands, resembling a #2 pencil’s thickness, near the scalp yields 100mg of hair, which is ideal for testing and verification. For EtG, supplemental analyses, and/or screens surpassing 10 panels, a recommendation of 150mg of the specimen is given. We advise weighing the sample using a jeweler’s scale. If scalp hair is lacking, an equivalent amount of body hair is viable for collection. References to head hair pertain solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial entry into the laboratory's framework. This process ensures the sample is correctly sealed and delivered, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry absent in an electronic chain of custody system.
The Screening phase provides an initial assessment for the presence of drugs of abuse. While Screening offers a budget-friendly means to rule out drug use in most samples, any positive results must undergo confirmation to be viable in court. Samples with presumptively positive screenings require further confirmation.
Should a sample indicate a presumptive positive in Screening, more hair is extracted from the original sample and prepared for the Extraction phase. Here, drugs are extracted at significantly lower concentrations compared to other testing methods (e.g., urine or oral fluid), making hair drug analysis particularly challenging.
Confirmation of positive results from the Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive undergo washing prior to confirmation as required. The complete laboratory procedure, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair designation standards and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite the term "hair follicle tests", the analysis focuses on the hair strand and not the follicle beneath the scalp.
