Hair testing is now regarded as an effective method for uncovering drug and alcohol usage. Hair gives a chronological record of alcohol and drug intake by holding biomarkers within the fibers of the emerging hair strand. Collected from the scalp vicinity, hair can offer up to around a three-month detection duration for alcohol and drugs. It is straightforward to gather, relatively challenging to tamper with, and convenient to transport.
A 1.5-inch sample with roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp offers 100mg of hair, which is the preferred specimen size for screening and confirmation. For EtG, ancillary analysis, and/or extensive panels above 10, 150mg of the hair sample is suggested. Using a jeweler’s scale for weighing the sample is advised. Should scalp hair be inaccessible, an equivalent quantity of body hair can be collected. "Head hair" denotes only the scalp hair, while "body hair" pertains to all other types (e.g., facial, axillary).
Process Overview
The chief procedures in the laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial management of a specimen within a laboratory’s framework. This process confirms the sample's integrity in terms of sealing and shipping, assigns it a random LAN (Laboratory Accessioning Number), and concludes any supplementary data input not provided by a digital chain of custody mechanism.
Screening is a preliminary swift evaluation for drugs of abuse. While Screening serves as an economical method to dismiss drug consumption in most samples, a positive screen must undergo confirmation to remain valid in legal scenarios. Any samples indicating a potential positive in Screening necessitate further confirmation.
Should a sample indicate potential positivity in Screening, additional hair is extracted from the initial specimen and processed for Extraction. At this stage, substances are retrieved from hair at significantly lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug screening the most laborious methodology to conduct.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all samples with potential positivity are cleansed as necessary. The complete lab procedure ranging from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair criteria and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly termed "hair follicle tests", the analysis is conducted on the hair strand instead of the follicle below the scalp.
