Utilization of hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a long-lasting record of alcohol and drug intake by embedding biomarkers within the fibers of the hair as it grows. When head hair is gathered near the scalp, it can deliver up to roughly a 90-day detection period for alcohol and drugs. Hair is straightforward to collect, relatively challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches containing around 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields approximately 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional testing, and/or testing surpassing 10 panels, about 150mg of the hair specimen is advisable. We suggest using a jeweler’s scale to weigh the sample. Should scalp hair be unavailable, a similar amount of body hair can be acquired. Reference to head hair specifically means scalp hair. Body hair pertains to other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result primarily consists of four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary incorporation of a sample into a laboratory’s system. This involves ensuring the sample is properly sealed and shipped, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any essential data input not included in an electronic chain of custody system.
Screening entails an initial swift examination for substances of abuse. Screening serves as a cost-efficient approach to exclude drug use for the majority of samples; nonetheless, a positive screening outcome necessitates confirmation to be deemed admissible in legal proceedings. Samples appearing presumptively positive during Screening will require follow-up confirmation.
In cases where a sample is presumptively positive during the Screening phase, additional hair is extracted from the initial specimen for the Extraction stage. In this phase, drugs are extracted from hair at concentrations significantly lower than those found in other methodologies (e.g., urine or oral fluid), making hair drug screening a complex methodology to conduct.
Verification of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive are washed before confirmation if necessary. The complete laboratory process from Accessioning through to Confirmation undergoes review for both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", this procedure examines the hair strand rather than the follicle beneath the scalp.
