Hair analysis has become recognized as an effective method for detecting drug and alcohol consumption. Hair retains a record of alcohol and drugs over time by capturing biomarkers within the fibers as the hair grows. When gathered near the scalp, hair can reflect a detection span of up to around three months for alcohol and other drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A sample of 1.5 inches, consisting of roughly 200 hair strands (similar to the thickness of a #2 pencil) nearest the scalp, yields 100mg of hair, which is the preferred quantity for both preliminary and confirmatory testing. For EtG, extra analyses, and/or assessments that exceed 10 panels, a 150mg specimen is advised. It is recommended to measure the specimen using a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair may be used. When mentioning head hair, it specifically refers to scalp hair alone. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial intake of a sample into the laboratory’s system. This phase includes ensuring the sample was securely sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry omitted by an electronic chain of custody system.
Screening consists of an initial rapid assessment for substances of abuse. While Screening is an economical method to exclude drug usage for most samples, a positive screen must be confirmed for it to be admissible in legal proceedings. Samples that are tentatively positive during Screening require further confirmation.
If Screening suggests a positive result, additional hair is removed from the initial sample for preparation in the Extraction stage. In this phase, drugs are removed from hair at significantly lower concentrations than in other testing methods (e.g., urine or oral fluids), making hair drug screening the most complex method to conduct.
Affirmation of any positive results from Screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples labeled as presumptive positive are cleaned before confirmation as needed. The comprehensive laboratory process from Accessioning to Confirmation is reviewed following both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 benchmarks.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests," the analysis is conducted on the hair strand itself and not the below-the-scalp hair follicle.
