Hair Follicle Drug Testing - Flower Mound, TX

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair retains biomarkers within the fibers as it grows, providing a lengthy history of substance use. When taken near the scalp, hair offers a detection period of up to roughly three months for alcohol and other drugs. Collection is straightforward, modification is challenging, and transporting it is uncomplicated.

A sample measuring 1.5 inches with around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, an optimal amount for testing and validation. For EtG, additional substances, and/or tests beyond 10 panels, a 150mg sample is suggested. The sample’s weight should preferably be measured with a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair, whereas body hair includes all other types (such as facial and axillary).

Process Overview

The primary phases in the drug test result processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the start of integrating a sample into the lab’s system. This phase ensures the sample is correctly sealed and transported, a random Laboratory Accessioning Number (LAN) is assigned, and any necessary data entry beyond what the electronic chain-of-custody provides is completed.

Screening serves as an initial evaluation for substances of abuse. Though a cost-efficient strategy to eliminate drug use in most samples, a positive screening requires confirmation to be legally valid. Presumptive positives in Screening necessitate additional confirmation.

Upon finding a presumptive positive during Screening, extra hair is extracted from the initial sample for the Extraction phase. Here, drugs are removed from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), underscoring the intricate nature of hair drug testing.

Positive screenings undergo confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo necessary washes before confirmation. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extensive detection duration: Hair drug tests capture drug use up to 90 days, in contrast to urine tests which offer shorter detection periods.
• Hard to tamper with: Hair drug tests are exceedingly tough to tamper with, yielding more precise results.
• Chronological usage insight: The test reflects a timeline of drug use over time, beyond just recent consumption.

Limitations:

• Recent consumption undetectable: Drugs take roughly 5-7 days to become noticeable in hair.
• Expense: Generally, hair drug tests incur higher costs compared to other drug testing methods.
• Variability in outcomes: Elements like hair color and individual hair growth variations can impact drug metabolite levels in hair.

Note: Despite frequently being called "hair follicle tests," the analysis targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing detection capabilities, hair follicle testing in Flower Mound, TX, offers superior accuracy over traditional urine tests. Hair tests can uncover substance use over a longer duration, which is crucial for employers aiming to maintain a drug-free workplace environment.
