Hair Follicle Drug Testing - Wyocena, WI

What it is, How it works

Hair testing now plays a pivotal role in identifying drug and alcohol consumption. Hair captures a long-term record of substance use by locking in biomarkers within its growing strands. When sampled near the scalp, hair offers up to a three-month detection period for various substances. The process of collecting hair is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (equivalent to the diameter of a #2 pencil) cut nearest to the scalp will provide 100mg of hair, which is the preferred sample size for initial analysis and verification. For EtG and/or extensive panel tests beyond 10, 150mg of hair is advisable. We suggest using a jeweler's scale to weigh the sample. In cases where scalp hair isn't available, a comparable amount of body hair should be collected. When we refer to head hair, we mean scalp hair specifically, while body hair refers to other types like facial and axillary hair.

Process Overview

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

Accessioning marks the sample's entry into the lab's system. This phase checks the proper sealing and shipping of samples, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry missing in the electronic chain of custody.

Screening serves as an initial assessment for substance abuse. Though screening provides a cost-efficient means to rule out drug use for most samples, positive screenings must be verified for legal proceedings. Hence, samples with presumptive positives from screening require a confirming step.

Should a sample test positive at the Screening stage, more hair is extracted from the original sample for the Extraction process. At this juncture, substances are drawn out from hair at significantly lower concentrations compared to other methods (like urine or saliva), making hair drug screening the most challenging methodology to execute.

An authentic positive screening result is corroborated using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive test samples undergo pre-confirmation washing as necessary. The whole lab procedure, from Accessioning through Confirmation, is scrutinized per the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug consumption for up to 90 days, unlike urine tests which have a shorter detection span.
• Difficulty to cheat: It's extremely challenging to falsify a hair drug test, thus ensuring more reliable results.
• Provides historical data: It reveals a trend of drug utilization over an extended timeframe rather than just recent use.

Limitations:

• Cannot detect recent use: It needs about 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests generally come with a higher price tag compared to other testing methods.
• Variations in results: Differences in hair color and personal hair growth rates can influence the levels of drug metabolites in the hair.

Note: While commonly termed as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
