Hair Follicle Drug Testing - Revillo, SD

What it is, How it works

Hair analysis is increasingly considered a potent method for detecting drug and alcohol consumption. Hair offers a prolonged timeline of drug and alcohol usage by capturing biomarkers in the strands. When hair is taken near the scalp, it can reveal usage patterns over roughly a 3-month span for both alcohol and drug detection. The collection process for hair is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (approximately the size of a #2 pencil) from near the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of hair is advisable. It is suggested to measure the sample weight with a jeweler’s scale. If scalp hair isn't accessible, a comparable amount of body hair may be used. References to head hair indicate only scalp hair. Body hair pertains to all other hair types (e.g., facial, axillary).

Process Overview

The four principal phases of processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into the lab's system, which includes confirming proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining manual data entry not covered by an electronic custody system.

Screening serves as an initial rapid assessment for drug abuse. Although cost-efficient for dismissing drug use in most samples, a positive screening result must be confirmed to be court-admissible. Any samples that show a presumptive positive in Screening require follow-up confirmation.

For samples with a presumptive positive in Screening, additional hair is taken from the primary sample and prepared for Extraction. During extraction, drugs are isolated from hair at significantly lower concentrations than other methods (like urine or oral fluid), which is why hair drug screening is notably challenging.

Through GC/MS, GC/MS/MS, or LC/MS/MS, any positive screen results are confirmed. All presumptive positive specimens receive a wash before confirmation as necessary. The entire process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can detect substance use for up to 90 days, compared to the shorter detection period of urine tests.
• Reduced likelihood of tampering: Cheating a hair drug test is notably difficult, enhancing the accuracy of results.
• Offers historical insight: Hair testing can reveal a pattern of drug consumption over time, not just recent activity.

Limitations:

• Inability to detect recent use: It typically takes 5-7 days for drugs to become detectable in hair strands.
• Expense: Hair drug tests are generally costlier than other drug testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Often labeled as "hair follicle tests", the examination evaluates the hair shaft and not the follicle beneath the scalp.
