Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other drug behavior by embedding biomarkers in the hair strand as it grows. When hair is collected near the scalp, it can reveal drug and alcohol use for up to roughly a 3-month span. Hair is straightforward to gather, relatively resistant to tampering, and can be shipped with ease.
A 1.5-inch section comprising approximately 200 hair strands (approximating the size of a #2 pencil) from the scalp will yield 100mg of hair, which is the optimal sample size for both screening and confirmation tests. For more extensive panels or testing including EtG, 150mg of the sample is advisable. It's suggested to measure the sample with a jeweler’s scale. Should scalp hair be unavailable, a comparable amount of body hair can be utilized. The term "head hair" specifically means scalp hair only, while "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
There are four fundamental phases in the laboratory process of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the introductory processing of a sample within a laboratory system, ensuring that it was suitably sealed and delivered, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any requisite data entries that may not be covered by an electronic chain of custody system.
Screening is a preliminary examination for potential drugs of abuse. While Screening presents a cost-efficient approach to exclude drug use in most specimens, a positive result in Screening must undergo confirmation to be legally admissible in court. Samples that yield a presumptive positive in Screening necessitate a follow-up confirmation.
When a sample is presumed positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. During Extraction, drugs are isolated from hair at a concentration significantly lower than other methods (such as urine or oral fluids), making hair drug screening the most challenging procedure to execute.
Confirmation of any positive results from Screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing if required prior to confirmation. The entire laboratory procedure from Accessioning through to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and the accreditation standards of ISO / IEC 17025.
