Hair Follicle Drug Testing - Marshall, MO

What it is, How it works

Hair testing is increasingly recognized as an effective means for detecting the presence of drugs and alcohol. By trapping biomarkers in the fibers of the growing hair strand, hair provides a comprehensive look back at substance use over an extended period. When collected near the scalp, hair can offer a detection range for alcohol and drugs of up to about three months. It is straightforward to collect, harder to tamper with, and simple to mail.

A sample of 1.5 inches composed of roughly 200 hair strands (equivalent to a #2 pencil diameter) closest to the scalp provides 100mg of hair, which is the optimal sample for both screening and confirmation processes. For tests such as EtG, additional tests, and those exceeding 10 panels, a sample size of 150mg is recommended. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair is unavailable, an equivalent quantity of body hair can be used. Reference to head hair implies specifically scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

There are four primary stages in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage that integrates a sample into the lab's system. It entails verifying the proper sealing and shipping of the sample, creating a random LAN (Laboratory Accessioning Number), and completing any data entry not handled by an electronic chain of custody system.

Screening is the preliminary check for drugs of abuse. While this stage provides a cost-efficient way to eliminate drug use for most samples, a positive screen necessitates confirmation to be legally defensible. Any samples that show presumptive positivity in Screening require additional confirmation.

In cases where a sample is presumptively positive during Screening, additional hair is taken from the initial specimen for the Extraction phase. Here, drugs are extracted from the hair at lower concentrations than other methods (such as urine or oral fluid), making hair drug screening one of the most complex methodologies to conduct.

GC/MS, GC/MS/MS, or LC/MS/MS are used to confirm positive screening results. All presumptive positive samples undergo washing prior to confirmation, as needed. The entire process—from Accessioning to Confirmation—is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, which is longer than the detection period for urine tests.
• Hard to falsify: Cheating on a hair drug test is quite challenging, leading to more reliable outcomes.
• Offers historical data: The test can provide insights into drug use patterns over a duration, rather than just recent consumption.

Limitations:

• Cannot detect recent use: It requires 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests generally cost more than alternative drug testing techniques.
• Variability in outcomes: Factors such as hair color and individual differences in hair growth may impact the concentrations of drug metabolites in hair.

Note: Commonly referred to as "hair follicle tests," the analysis is performed on the hair strand and not the follicle beneath the scalp.
