Hair Follicle Drug Testing - Belle Meade, TN

What it is, How it works

Hair testing is increasingly recognized as an effective method for uncovering drug and alcohol consumption. Hair retains a record of drug and alcohol use by entrapping biological markers in the fibers of the hair as it grows. When taken from near the scalp, hair can offer a detection period of up to roughly three months for drugs and alcohol. Hair is easy to collect, not easily tampered with, and straightforward to transport.

A sample measuring 1.5 inches, containing approximately 200 hairs (comparable to a #2 pencil's girth) nearest the scalp, delivers 100mg of hair, which is the optimal sample mass for testing. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of hair is advisable. It's suggested to determine the sample’s weight using a jeweler’s scale. If scalp hair isn't available, one can gather an equivalent quantity of body hair. When discussing head hair, scalp hair is implied. Body hair includes every other type of hair (facial, axillary, etc.).

Process Overview

The workflow for processing a drug test in a lab typically includes the following four stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial steps of integrating a specimen into a laboratory’s cataloging system. This phase ensures that the specimen was securely sealed and transported, assigns it a unique LAN (Laboratory Accessioning Number), and performs any supplementary data input not incorporated by a digital chain of custody system.

Screening is a preliminary test to identify potential drugs of abuse. Although Screening offers a cost-efficient strategy to identify drug consumption in most samples, any positive screen needs validation for legal proceedings. Samples that test presumptively positive during Screening must undergo subsequent confirmation.

If a Screening result suggests positivity, additional hair is drawn from the initial sample for the Extraction process. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), marking hair drug testing as a complex procedure to perform.

To verify any positive results from the screening, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are utilized. All samples with presumptive positive results are cleansed before confirmation as deemed necessary. The complete lab procedure from Accessioning through Confirmation is supervised under both the CAP (College of American Pathologists) Hair classification and conforms to ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug trials can reveal drug intake for as long as 90 days, unlike urine testing which has a briefer detection period.
• Challenging to manipulate: Cheating a hair drug examination is highly unlikely, enhancing result reliability.
• Offers past usage insight: It shows a pattern of drug usage over time, rather than just recent use.

Limitations:

• Incapable of detecting new use: Drugs generally require around 5-7 days to become traceable in hair.
• Expense: Hair drug tests tend to be costlier than other drug test methods.
• Outcome variability: Elements such as hair pigmentation and personal hair growth differences can impact the concentration of drug byproducts in hair.

Note: Commonly called "hair follicle tests", the actual test evaluates the hair strand and not the follicle beneath the scalp
