Hair Follicle Drug Testing - Brill, WI

What it is, How it works

Hair testing is increasingly recognized as an effective resource for identifying drug and alcohol consumption. Hair offers an extended historical record of alcohol and drug intake by embedding biomarkers within the strands of the hair as it grows. If collected near the scalp, hair can reflect around a three-month period of alcohol and drug use. The collection process for hair samples is straightforward, making it challenging to tamper with and simple to transport.

A sample measuring 1.5 inches comprising roughly 200 strands of hair (roughly equivalent to the size of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal quantity for both screening and confirmation processes. For EtG, auxiliaries, or tests exceeding 10 panels, it is advisable to provide 150mg. It is recommended to utilize a jeweler’s scale to weigh the sample. Should scalp hair not be available, a similar quantity of body hair can be collected. Specifically, head hair pertains solely to scalp hair, while body hair includes every other hair type (such as facial, axillary, etc.).

Process Overview

The laboratory procedure for processing drug test results encompasses four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial management of a sample within the lab’s system. This phase ensures the sample was securely sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent in the electronic chain of custody framework.

The Screening phase involves an initial rapid assessment for substance abuse. Screening offers a cost-effective method to negate drug use in most samples; however, a positive result must be verified for legal acceptability. Samples that yield presumptive positive results during Screening necessitate subsequent confirmation.

Should a sample register a presumptive positive in Screening, additional hair is gathered from the original sample for the Extraction phase. This step involves extracting drugs from hair at concentrations notably lower than other testing methods (such as urine or oral fluid), underscoring the complexity of hair drug screenings.

The Confirmation of any positive result from Screening is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before confirmation as required. The complete lab process, from Accessioning through Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for as long as 90 days, whereas urine tests offer a more condensed detection window.
• Immune to cheating: Hair drug tests are notoriously difficult to manipulate, enhancing the accuracy of results.
• Chronological data: They provide insights into drug use patterns over time, rather than merely recent consumption.

Limitations:

• Not suitable for recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be costlier compared to other drug testing methods.
• Result variances: Hair color and personal hair growth differences can influence the drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the analysis targets the hair strand, excluding the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

The advantages of hair follicle testing over urine tests are substantial in Brill, WI. Hair testing offers a superior detection window and remains the most reliable method in identifying drug use.
