Hair Follicle Drug Testing - Cylinder, IA

What it is, How it works

Hair testing has emerged as a significant method for identifying drug and alcohol use. It offers a comprehensive history of substance interaction, capturing biomarkers in the fibers of the hair shaft as it grows. By acquiring a sample near the scalp, a detection timeframe of up to 90 days for substances can be achieved. This method of sample collection is straightforward, challenging to tamper with, and conveniently transportable.

Collecting a 1.5-inch segment of around 200 hair strands (approximately the girth of a #2 pencil) closest to the scalp yields 100mg of hair, which is considered the perfect sample size for initial screenings and verifications. For additional verifications, such as EtG or tests exceeding 10 panels, a 150mg hair specimen is advisable. We suggest using a jeweler’s scale to measure the sample. If scalp hair cannot be provided, a comparable amount of body hair can be utilized. Here, head hair refers strictly to scalp hair, while body hair includes all other types (like facial or axillary hair).

Process Overview

There are four core stages in processing a drug test result at the laboratory: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is initially processed into the laboratory's records. It incorporates verifying that the sample was properly sealed and delivered, assigning a unique LAN (Laboratory Accessioning Number), and completing any needed data input not covered by an electronic system for chain of custody.

The Screening phase involves an initial check for drug presence. Although it provides an affordable means to dismiss substance usage for most samples, any tentative positive results require confirmation for legal validity. Samples with positive preliminary results mandate further confirmation.

In cases of preliminary positive results in the Screening phase, additional hair is taken from the original sample and prepped for Extraction. This step involves extracting drugs at much lower concentrations than other methods (such as in urine or saliva tests), making hair drug screening a particularly challenging method to execute.

Positive screening results are verified through GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo a washing process before the confirmation stage if necessary. The complete lab process, from Accessioning through Confirmation, complies with the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify substance use for up to three months, whereas urine tests offer a shorter detection timeframe.
• High integrity: The robustness of a hair drug test minimizes the potential for cheating, ensuring greater accuracy.
• Historical insights: Provides data about drug usage patterns over time, rather than recent usage only.

Limitations:

• Inability to detect recent use: It takes approximately one week for drugs to show up in hair samples.
• Expense: Hair tests generally incur higher costs compared to alternative drug testing methods.
• Result variability: Factors like hair color and personal differences in hair growth can influence the levels of drug residues found in hair samples.

Note: Commonly termed "hair follicle tests", these analyses actually examine the hair strand, not the follicle located under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing surpasses urine testing in Cylinder, IA by offering a longer detection window.
