Hair Follicle Drug Testing - Johnsonville, IL

What it is, How it works

Hair testing is now recognized as a crucial method for identifying drug and alcohol consumption. Hair captures a long-duration record of alcohol and other substances by securing biomarkers within the fibers of the hair as it grows. When hair is collected near the scalp, it can reveal usage history for drugs and alcohol for up to roughly 3 months. The collection process is straightforward, it's relatively tamper-proof, and easy to send for analysis.

A sample measuring 1.5 inches, equating to about 200 strands (roughly the thickness of a #2 pencil) taken closest to the scalp, yields 100mg of hair, which is the optimal sample size for both screening and confirming results. For tests involving EtG, additional panels, or those surpassing 10 panels, a 150mg specimen is advised. It's suggested to measure the specimen with a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. References to head hair specifically mean scalp hair, while body hair encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about the initial intake of a sample into the lab’s system. This step ensures that the sample has been appropriately sealed and sent, assigns it a unique LAN (Laboratory Accessioning Number), and completes any additional data input missing from an electronic chain of custody system.

Screening is a preliminary process for detecting drug abuse. Although it serves as a cost-effective measure to exclude drug use in most cases, a screen that tests positive must be confirmed for it to be valid in legal contexts. Any samples that show a presumptive positive in Screening must have secondary confirmation.

Should a sample indicate a presumptive positive in Screening, further hair is extracted from the original sample and prepared for Extraction. Drugs are extracted from hair at considerably lower concentrations than with other methods (like urine or saliva), making hair drug screening a notably challenging technique.

Positive screening results go through Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presuming positive samples are cleansed before confirmation, as needed. The entire laboratory process, from Accessioning through Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection range.
• Challenging to falsify: Hair drug tests are hard to cheat on, making the findings more reliable.
• Offers historical insight: It presents a pattern of drug use over time, not just recent activity.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug testing is typically costlier than other testing approaches.
• Result variability: Aspects like hair pigmentation and personal differences in hair growth can impact drug metabolite levels in hair.

Note: Although often labeled as "hair follicle tests," the analysis is conducted on the strand of hair, not the follicle beneath the scalp.
