Hair Follicle Drug Testing - Lafayette, MN

What it is, How it works

Hair testing is increasingly valued for its effectiveness in identifying drug and alcohol use. It offers a prolonged history of substance use by retaining biomarkers within the fibers of the emerging hair strand. When hair is collected from the scalp, it can allow for a drug and alcohol detection timeline of up to about three months. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

Collecting a 1.5-inch section of approximately 200 hair strands near the scalp provides around 100mg of hair, which is ideal for screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of hair is advised. Utilizing a jeweler's scale for weighing the sample is suggested. In cases where scalp hair is not available, a similar quantity of body hair can be used. By head hair, we mean scalp hair only, whereas body hair refers to any other hair, including facial or axillary hair.

Process Overview

There are four primary stages in processing a drug test result in the laboratory: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial phase of a sample being incorporated into a lab's database. This stage includes checking that the sample is properly sealed and shipped, assigning it a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not covered by an electronic chain of custody system.

Screening provides an initial, quick check for drug misuse. It serves as a cost-effective means to dismiss drug use in most samples, although a positive screen must be confirmed to be court-admissible. Samples that test positive during Screening must undergo further confirmation.

If a sample tests positive in the Screening step, additional hair is taken from the sample for Extraction. This stage involves extracting drugs from hair, where concentrations are much lower than in other methods like urine or oral fluid testing, making hair drug testing the most challenging method to execute.

For Confirmation, positive screening results undergo testing via GC/MS, GC/MS/MS, or LC/MS/MS. Samples with positive preliminary results are cleaned prior to Confirmation when necessary. The entire lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair guidelines and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, offering a longer window than urine tests.
• Difficult to manipulate: Cheating a hair drug test is notably challenging, resulting in more precise outcomes.
• Tracks historical use: The tests provide an overview of drug use patterns over time rather than just recent use.

Limitations:

• Inability to detect recent use: Drugs are detectable in hair after about 5-7 days.
• Expense: Hair drug tests often cost more than alternative testing methods.
• Result variations: Elements like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Frequently misnamed as "hair follicle tests," the focus is on analyzing hair strands rather than the follicles beneath the scalp.
