Recognized as a robust method for detecting substance and alcohol consumption, hair testing offers a detailed timeline by capturing markers within the hair’s growing fibers. When cut near the scalp, hair can provide insight into alcohol and drug use spanning approximately 3 months. This method is easy to execute, challenging to tamper with, and straightforward to transport.
A 1.5-inch portion consisting of about 200 hair strands (approximately the width of a #2 pencil) from near the scalp equals 100mg of hair, which is the preferred sample for testing and verification. For EtG, supplementary tests, or panels exceeding 10, 150mg of hair is suggested. Using a jeweler’s scale is advised for measuring the sample. If scalp hair is not an option, an equivalent weight of body hair may be used. In context, “head hair” specifically means scalp hair only, while “body hair” covers all other types, including facial and axillary.
Process Overview
The primary phases in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples enter a lab’s system. This step involves verifying that samples have been sealed and transported accurately, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any extra data not provided by an electronic custody chain.
Screening offers an initial, cost-effective drug usage assessment. Although it efficiently rules out drug use in most samples, positive screenings need confirmation to be used in legal settings. Any presumptive positive screenings must undergo secondary confirmation.
If Screening suggests a positive, more hair is taken from the original sample for Extraction. Drugs are extracted at lower concentrations from hair compared to other methods (such as urine or oral fluid), making hair drug screening the most intricate method.
Confirmation for positive screenings is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleaned before confirmation if necessary. Every lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
