Hair Follicle Drug Testing - Harviell, MO

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. By capturing biomarkers within the fiber of the hair strand as it grows, hair provides a prolonged record of alcohol and other drug usage. When taken in close proximity to the scalp, hair can offer a detection window of up to around 90 days for substances. It is straightforward to collect, relatively resistant to tampering, and convenient to transport.

A 1.5-inch segment comprising close to 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is considered ideal for both screening and confirmation. For EtG, additional tests, or analysis exceeding 10 panels, it is advisable to procure 150mg of hair. We advocate for utilizing a jeweler's scale for weighing. In cases where scalp hair isn't accessible, a comparable quantity of body hair can be gathered. When mentioning head hair, it solely pertains to scalp hair, while body hair encompasses all other kinds (facial, axillary, etc.).

Process Overview

The primary phases in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step to integrate a sample into the lab's system, which covers ensuring the sample was properly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody protocol.

Screening is initially performed as a rapid examination for substances. Although Screening is a cost-efficient means to exclude drug usage in most cases, a positive screen must be confirmed for it to be considered valid in legal proceedings. Samples presumed positive during Screening necessitate further confirmation.

Should the Screening stage yield a presumed positive result, additional hair is extracted from the original sample for Preparation in the Extraction phase. Here, the drug substances are isolated from the hair at significantly lower concentrations compared to other methods (for instance, urine or oral fluid), highlighting the complexity of conducting hair drug testing.

Confirmation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumed positive samples undergo washing as required prior to confirmation. The complete lab procedure from Accessioning to Confirmation meets the CAP (College of American Pathologists) Hair identification criteria and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests, which have a shorter detection limit.
• Hard to falsify: Cheating a hair drug test is highly challenging, hence results tend to be more precise.
• Offers historical insight: The test can trace drug use trends over a duration, rather than merely recent consumption.

Limitations:

• Unsuitable for detecting recent usage: Detection in hair typically requires about 5-7 days post-consumption.
• Expense: Hair drug analyses tend to be costlier compared to other methods of drug testing.
• Result variability: Hair color and individual growth rates can influence metabolite concentrations in hair.

Note: Despite often being termed "hair follicle tests", the procedure examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
