Hair Follicle Drug Testing - Redwood, MS

What it is, How it works

The effectiveness of hair testing as a method for detecting substance use, including drug and alcohol consumption, has gained recognition. Hair encapsulates a prolonged history of substance use by embedding biomarkers within the growing hair fibers. When harvested near the scalp, the hair offers a detection period of up to around three months for identifying alcohol and drug usage. Hair collection is straightforward, challenging to tamper with, and easy to transport.

An ideal hair sample for analysis is a 1.5-inch segment, comprising roughly 200 strands (equivalent to the thickness of a #2 pencil), closest to the scalp, yielding 100mg for testing. For EtG, additional panels, or tests exceeding 10 panels require 150mg of hair. We suggest using a jeweler's scale for weighing the specimen. If scalp hair cannot be obtained, an equivalent amount of body hair is acceptable. When mentioning head hair, we specifically mean scalp hair, while body hair encompasses other types such as facial or axillary hair.

Process Overview

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

Accessioning pertains to the initial integration of a sample into a lab's system. This step checks the correct sealing and shipping of the sample, assigns it a random Laboratory Accessioning Number (LAN), and concludes any necessary manual data entry absent from the electronic chain of custody.

Screening offers a preliminary assessment for substance abuse detection. While it serves as an economical method to dismiss drug use in most cases, a confirmed positive result is necessary for legal proceedings. Thus, any samples showing a presumptive positive result in Screening require further confirmation.

For samples with presumptive positive results during Screening, additional hair is extracted from the original sample for further Extraction. In this stage, drugs are extracted from hair at significantly lower concentrations compared to methods like urine or oral fluid, highlighting the complexity of hair drug testing.

For Confirmation, positive screening results undergo GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive signs are cleansed before confirmation, if required. The complete laboratory workflow, from Accessioning to Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can track drug use history for up to 90 days, unlike urine tests that offer a shorter detection period.
• Resilience against tampering: Hair drug testing is difficult to manipulate, enhancing the accuracy of results.
• Captures usage trends: This method can trace drug consumption patterns over time rather than just recent usage.

Limitations:

• Inability to detect recent consumption: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair testing usually incurs higher costs compared to other drug testing techniques.
• Inconsistent results: Factors such as hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although often termed as "hair follicle tests," the actual analysis pertains to the hair strand, not the follicle beneath the scalp.
