Hair Follicle Drug Testing - Vergennes, IL

What it is, How it works

Hair testing is considered an effective method for detecting drug and alcohol consumption. It offers an extended historical account of substance use by encapsulating biomarkers within the growing hair's fibers. When sampled close to the scalp, hair can show alcohol and drug presence for up to 90 days. Hair collection is straightforward, hard to tamper with, and easy to transport.

A 1.5-inch sample containing approximately 200 hair strands (similar in diameter to a #2 pencil) closest to the scalp will weigh around 100mg, optimal for both screening and confirmation. For EtG, add-ons, and tests beyond 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale for weighing the specimen is suggested. If scalp hair cannot be collected, a comparable amount of body hair is acceptable. References to head hair pertain only to scalp hair, while body hair includes all other areas (facial, axillary, etc.).

Process Overview

The main stages of lab processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into the lab's system. This step checks that the sample is adequately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.

Screening entails a quick initial assessment for drugs. Screening is a cost-efficient way to exclude drug use in most samples; however, a positive screen must be confirmed for court admissibility. Samples that are presumptively positive in Screening necessitate further confirmation.

If Screening suggests a positive result, additional hair is extracted from the sample for Extraction. During this stage, drugs are extracted at a lower concentration than other methods (e.g., urine or oral fluid), making hair screening notably challenging.

Using GC/MS, GC/MS/MS, or LC/MS/MS, positive Screening results undergo Confirmation. Before Confirmation, presumptive positive samples are cleaned as required. The complete process from Accessioning to Confirmation is validated under the CAP (College of American Pathologists) Hair standard and accredited to ISO / IEC 17025.

Advantages of hair drug testing:

• Long detection period: Hair tests can trace drug intake for up to 90 days, as opposed to urine tests which have a reduced detection window.
• Challenging to falsify: Hair drug tests are tough to evade, enhancing result reliability.
• Yields historical insight: It can illustrate a drug use trend over time, beyond just recent consumption.

Limitations:

• Fails to indicate recent use: Detection in hair takes about 5-7 days.
• Expense: Generally, hair tests are pricier than other testing approaches.
• Result variability: Attributes such as hair color and growth differences can influence drug metabolite levels in hair.

Note: Though often termed "hair follicle tests", the test examines the hair fiber, not the follicle below the scalp
