Hair Follicle Drug Testing - Gluek, MN

What it is, How it works

Hair analysis is increasingly recognized as a robust method for detecting drug and alcohol consumption. It offers an extended historical record of substance use by capturing biomarkers within the fibers of developing hair strands. When procured close to the scalp, hair specimens can reveal drug and alcohol usage history spanning up to three months. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

Acquiring a 1.5-inch segment consisting of around 200 hair strands (equivalent to a #2 pencil’s width) from near the scalp yields 100mg of hair, the optimal amount for both initial checks and confirmatory testing. For EtG, additional checks, or filters exceeding 10 panels, 150mg of the hair sample is advocated. It's advisable to use a jeweler’s scale to weigh the collection. Should scalp hair be inaccessible, a comparable mass of body hair is acceptable. The term "head hair" strictly denotes scalp hair, while "body hair" encompasses all other varieties (like facial or axillary).

Process Overview

The process in the lab for a drug testing result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary processing of the collected sample within the laboratory system. This procedure confirms the sample's proper sealing and shipping, the assignment of a random Laboratory Accessioning Number (LAN), and the completion of any additional data entry absent from an electronic chain of custody system.

Screening involves a preliminary rapid check for drug presence. While it serves as an economical method to exclude drug present in most samples, a positive result in Screening must undergo verification before it can be legally valid. Any samples preliminarily testing positive in Screening necessitate confirmation through further analysis.

When a sample indicates a presumptive positive at the Screening phase, additional hair is drawn from the initial sample for Extraction. Here, the concentration of drugs extracted from hair is much lower compared to other methods (like urine or oral fluid), highlighting why hair drug testing is the most complex methodology.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm any presumptive positive results. All preliminarily positive samples are washed as required before Confirmation. The complete laboratory procedure, from Accessioning to Confirmation, is thoroughly reviewed under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests identify drug intake up to 90 days prior, in contrast to urine tests with a shorter detection span.
• Difficult to falsify results: Cheating on a hair drug test is exceedingly challenging, thereby enhancing result reliability.
• Provides usage history: It can delineate a timeline of drug consumption over an extended period, rather than just recent activity.

Limitations:

• Unable to discern recent usage: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug tests tend to be costlier than other varieties of drug testing.
• Result variability: Attributes like hair color and individual hair growth variations may impact the concentration of drug metabolites present in hair.

Note: Though commonly termed as "hair follicle tests," this examination analyzes the hair strands, not the follicles beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Gluek, MN, hair follicle tests offer advantages over traditional urine testing by providing a more comprehensive drug detection timeline. This method is less susceptible to short-term abstinence masking, offering greater insight.
