Hair Follicle Drug Testing - Brook Park, MN

What it is, How it works

Hair testing is increasingly regarded as a robust method for identifying drug and alcohol consumption. This technique allows for the tracking of substance use over an extended period by capturing biomarkers within the growing hair fibers. When collected near the scalp, hair samples can reveal drug and alcohol usage for up to roughly a 3-month period. This method of sample collection is straightforward, less prone to tampering, and easy to transport.

A 1.5-inch sample comprising roughly 200 hair strands (comparable to the thickness of a #2 pencil) from the scalp can yield 100mg, which is ideal for both screening and confirmation processes. For EtG, add-ons, and/or testing beyond 10 panels, it is suggested to use 150mg of the hair specimen. It's advisable to use a jeweler’s scale for weighing the sample. In circumstances where scalp hair is scarce, equivalent amounts of body hair can be used. When we mention head hair, it specifically means scalp hair. Body hair encompasses any other types of hair (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result can be broken down into four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing to integrate into the laboratory’s system. This phase ensures the sample is properly sealed and shipped, assigns it a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry not covered by an electronic chain of custody system.

Screening serves as a preliminary analysis to identify drugs of abuse. Although Screening is a cost-efficient approach to eliminate drug use in most cases, a positive outcome requires confirmation to be court-admissible. Any samples with a presumptive positive result in Screening need a secondary confirmation.

When a sample tests presumptively positive in Screening, additional hair is extracted from the original specimen for further preparation in Extraction. In this phase, drugs are separated from hair at lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug tests particularly challenging to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed as needed before confirmation. Every stage of the laboratory process from Accessioning through Confirmation is monitored under both the CAP (College of American Pathologists) Hair designation and the standards of ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for as long as 90 days, which is longer than the duration for urine tests.
• Hard to falsify: It is extremely challenging to tamper with a hair drug test, enhancing the accuracy of the results.
• Shows usage history: It can reveal a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Incapable of detecting recent use: It requires about 5-7 days for drugs to become observable in hair samples.
• Expense: Hair drug tests are typically more costly compared to other drug testing techniques.
• Result variability: Elements such as hair color and individual differences in hair growth can influence the metabolite concentration in hair.

Note: Despite commonly being called "hair follicle tests", these tests assess the strand of hair, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
