Hair analysis is now acknowledged as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers in the fibers of the developing hair strand, offering a historical record of alcohol and drug use. When taken from near the scalp, hair can provide a detection period of up to roughly three months for alcohol and other substances. It is easy to collect hair, challenging to tamper with, and straightforward to transport.
A sample length of 1.5 inches, comprising approximately 200 hair strands (around the diameter of a #2 pencil) next to the scalp, yields 100mg, which is the standard sample size for screening and confirmation. For testing EtG, extra panels, or panels exceeding 10, a specimen of 150mg is advisable. We suggest using a jeweler’s scale for weighing the specimen. In cases where scalp hair isn't available, a similar amount of body hair can be used. 'Head hair' specifically refers to scalp hair, while 'body hair' includes other types such as facial or axillary hair.
Process Overview
The laboratory processing for a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory’s system. This process involves confirming that the sample was correctly sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and performing any data entry that isn't covered by an electronic chain of custody system.
Screening entails a preliminary rapid assessment for substances of abuse. Although Screening serves as a cost-efficient means to rule out drug use in most samples, any positive findings require confirmation for legal admissibility. Presumptive positives from Screening necessitate secondary confirmation.
For samples that test presumptively positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. At this stage, drugs are isolated from hair at lower concentrations than with other methods (such as urine or oral fluid), which makes hair drug testing the most challenging technique to execute.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the analysis involves the hair strand, not the follicle beneath the scalp.
