Hair Follicle Drug Testing - Lee, ME

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by capturing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can present up to about a 3-month detection timeframe for alcohol and other substances. Hair is effortless to gather, relatively hard to tamper with, and convenient to transport.

A 1.5-inch sample comprising approximately 200 strands of hair (equivalent to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample size for analysis and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the specimen is advised. We suggest weighing the specimen with a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair can be used. When mentioning head hair, we are referencing only scalp hair. Body hair refers to all other types of hair (facial, axillary, etc.).

Process Overview

The primary stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample into a laboratory’s system. This step involves confirming that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening involves an initial rapid check for illicit substances. While Screening is an economical option to rule out drug consumption on most samples, a positive screen must be verified to be legally admissible. Any samples that show a positive result in Screening undergo a secondary confirmation.

If a sample indicates a positive result during Screening, additional hair is extracted from the initial specimen and readied for Extraction. In this process, drugs are extracted from hair at a much lower concentration than in other techniques (e.g., urine or oral fluid), which is why hair drug analysis is the most challenging method to execute.

Confirmation of any positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug consumption for up to 90 days, in contrast to urine tests which have a limited detection window.
• Hard to manipulate: It is very challenging to falsify a hair drug test, resulting in more reliable outcomes.
• Offers historical information: It can exhibit a pattern of drug consumption over time, not merely recent usage.

Limitations:

• Cannot detect recent usage: It takes around 5-7 days for drugs to be identifiable in hair.
• Expense: Hair drug tests are generally pricier than other drug testing techniques.
• Result variations: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although frequently referred to as "hair follicle tests", the analysis itself examines the hair strand and not the hair follicle beneath the scalp
