Hair Follicle Drug Testing - Pine River, MN

What it is, How it works

Hair analysis has gained recognition as a robust method for detecting drug and alcohol consumption. Hair encapsulates a prolonged history of alcohol and other substances by embedding biomarkers within the fibers of the developing hair shaft. When gathered near the scalp, hair can reveal up to an estimated three-month period of alcohol and drug detection. Hair collection is straightforward, relatively tamper-proof, and uncomplicated to transport.

A hair specimen measuring 1.5 inches, approximately 200 strands (similar in size to a #2 pencil) nearest to the scalp, will produce 100mg of hair, an optimal sample for both screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, 150mg of the sample is advisable. A jeweler’s scale is suggested for accurate specimen weighing. In the event scalp hair is unavailable, a comparable quantity of body hair can be utilized. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other hair regions (facial, axillary, etc.).

Process Overview

There are four essential steps involved in the laboratory handling of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a laboratory’s system. This step involves confirming the sample was securely sealed and dispatched accurately, allocation of a random LAN (Laboratory Accessioning Number), and the completion of any supplementary data entry absent from an electronic chain of custody system.

Screening offers an expedient preliminary assessment for substance abuse. Despite Screening being a cost-efficient approach for excluding drug consumption in most samples, a positive screen requires substantiation to be legally acceptable. Samples that test presumptively positive during Screening necessitate a follow-up confirmation.

Should a sample display a presumptively positive result during Screening, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are withdrawn from hair at significantly lesser concentrations than in other methods (e.g., urine or oral fluid), rendering hair drug testing as the most challenging method to execute.

Verification of any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo requisite washing prior to confirmation. The comprehensive laboratory procedure spanning Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair criteria and accreditation in accordance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug testing can identify drug intake for as long as 90 days, unlike urine tests with a comparatively brief detection span.
• Difficult to manipulate: Evading a hair drug test is notably challenging, thereby enhancing result accuracy.
• Historical data provision: It offers a record of drug consumption patterns over a period of time, beyond just recent use.

Limitations:

• Incapable of detecting recent consumption: It generally requires 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug testing typically incurs higher costs compared to other drug testing approaches.
• Result variability: Elements such as hair color and individual differences in hair growth can impact drug metabolite concentrations within the hair.

Note: Commonly termed as "hair follicle tests", the test analyzes the hair strand rather than the follicle beneath the scalp.
