Hair Follicle Drug Testing - Evansville, MN

What it is, How it works

Hair analysis is considered a potent method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the fibers of the expanding hair strand. Obtained near the scalp, it can reveal up to a 3-month detection period for alcohol and drugs. Hair is easy to gather, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch specimen of approximately 200 hair strands (comparable to a #2 pencil) nearest to the scalp offers 100mg of hair, the optimal amount for evaluation and verification. For EtG, supplementary tests, and/or assessments exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the specimen using a jeweler’s scale. If scalp hair is lacking, a similar quantity of body hair may be collected. When mentioning head hair, we specifically mean scalp hair only. Body hair signifies all other hair types (facial, axillary, etc.).

Process Overview

The primary steps in laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial processing of a specimen into a laboratory’s framework. This entails confirming the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finishing any further data input not furnished by an electronic chain of custody system.

Screening involves an initial swift assessment for drugs of misuse. While Screening is a budget-friendly approach to dismiss drug usage in most samples, a positive screen requires validation to be valid in court. Samples presumptively positive in Screening necessitate a secondary confirmation.

If a sample shows presumptive positivity in the Screening step, additional hair is extracted from the initial specimen and readied for Extraction. In Extraction, drugs are drawn from hair at a markedly lower concentration than in other methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most challenging method to execute.

Confirmation of any positive screen result uses GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can identify drug use for up to 90 days, compared to urine tests that have a shorter window.
• Tough to manipulate: Manipulating a hair drug test is notably difficult, increasing result accuracy.
• Offers historical insight: It can demonstrate a drug use pattern over time, not merely recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests are generally pricier than other testing approaches.
• Result variability: Aspects such as hair color and individual hair growth disparities can influence drug metabolite concentration in hair.

Note: Often called "hair follicle tests", the evaluation actually examines the hair strand rather than the follicle beneath the scalp
