Hair Follicle Drug Testing - Randolph, VT

What it is, How it works

Hair testing is regarded as a powerful method for detecting drug and alcohol use. Hair can offer a historical record of substance use by trapping markers within the fibers of the growing hair strand. When obtained close to the scalp, hair has the capacity to present an approximately 3-month period for drug and alcohol detection. Collecting hair is straightforward, offers resistance to tampering, and is easily transportable.

An optimal sample for analysis, consisting of a 1.5-inch segment of about 200 hair strands (roughly the girth of a #2 pencil) closest to the scalp, provides 100mg of hair. For EtG, additional tests, or screenings exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair cannot be obtained, a similar amount of body hair may be used. In this context, head hair refers exclusively to scalp hair, while body hair encompasses all other hair categories (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the introduction of a sample into a lab’s system. This covers confirming that the sample is properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and concluding any extra data entry not included by an electronic chain of custody system.

Screening provides a preliminary check for potential drug abuse. Although Screening is an economical means of dismissing drug use in most samples, a positive screen must be corroborated to be valid in legal contexts. Any samples deemed presumptively positive during Screening must undergo secondary confirmation.

For samples deemed presumptively positive during the Screening phase, additional hair is extracted from the initial specimen to prepare for Extraction. This step involves extracting drugs from hair at a considerably lower concentration than other methods (such as urine or oral fluids), making hair drug screening the most complex methodology to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive samples are cleansed prior to confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug use up to 90 days, unlike urine tests which possess a briefer detection timeframe.
• Challenging to manipulate: It is exceptionally difficult to alter the results of a hair drug test, ensuring increased accuracy.
• Insightful historical pattern: It allows for the identification of a pattern of drug usage over time, rather than indicating only recent activity.

Limitations:

• Inability to detect recent abuse: About 5-7 days are necessary for drugs to manifest in hair.
• Expense: Hair drug tests typically incur higher expenses compared to alternative testing methods.
• Result variability: Factors like hair coloration and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: While sometimes described as "hair follicle tests", the examination actually involves the hair strand rather than the follicle located beneath the scalp.
