Hair Follicle Drug Testing - La Prairie, MN

What it is, How it works

Seen as a potent tool for identifying drug and alcohol usage, hair testing offers a lengthy history of substance intake by capturing biomarkers within the hair's growing fibers. When hair samples are taken near the scalp, they provide a detection timeframe of up to roughly three months for drugs and alcohol. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

An optimal sample for analysis and confirmation consists of a 1.5-inch segment of approximately 200 hair strands (about the size of a #2 pencil) near the scalp, providing 100mg of hair. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is advised. It's recommended to measure the sample using a jeweler’s scale. Should scalp hair be inaccessible, a similar weight of body hair can be collected. By "head hair," we mean scalp hair specifically, whereas "body hair" includes other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four principal stages: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample undergoes initial processing into a lab's system. This step verifies that the sample was properly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number) randomly, and completes any further data input not addressed by an electronic chain of custody system.

Screening entails a preliminary rapid evaluation for drug abuse. It serves as an economical means to exclude drug use in most samples, yet a positive outcome must be corroborated to be valid in legal settings. Samples deemed presumptively positive in Screening require subsequent confirmation.

For samples deemed potentially positive during Screening, more hair is extracted from the initial sample and processed for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug analysis is among the most challenging methodologies.

Confirmation of a positive screen result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed beforehand as necessary. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use up to 90 days, unlike urine tests which have a shorter window.
• Hard to manipulate: It's exceedingly challenging to deceive a hair drug test, thereby ensuring higher accuracy in results.
• Offers historical insight: It reflects a pattern of drug consumption over time, rather than just recent use.

Limitations:

• Inability to detect recent use: It takes roughly 5-7 days for drugs to become identifiable in hair.
• Expense: Hair drug tests typically cost more than other testing approaches.
• Result variability: Aspects like hair color and individual hair growth differences may influence the drug metabolite concentration in hair.

Note: While commonly dubbed "hair follicle tests," the analysis targets the hair strand itself, not the follicle beneath the scalp
