Hair Follicle Drug Testing - Patrick, SC

What it is, How it works

Hair testing has emerged as a significant method for identifying alcohol and drug presence. Hair captures a prolonged history of drug and alcohol use by embedding biomarkers within the hair's fibers as it grows. Hair samples collected near the scalp can offer a detection duration for substances like alcohol reaching up to about three months. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A hair sample, measuring 1.5 inches from the scalp and comprising roughly 200 strands (comparable to a #2 pencil’s width), will yield 100mg—ideal for screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, a 150mg specimen is advocated. Utilizing a jeweler’s scale for weighing the sample is advised. Should scalp hair be absent, an equivalent measure of body hair is a viable alternative. When addressing head hair, this pertains solely to scalp hair. Body hair includes all other varieties of hair (facial, axillary, etc.).

Process Overview

The process for achieving a drug test outcome entails four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial step of incorporating a sample into the lab’s system. This involves confirming the sample’s proper sealing and shipment, assigning a Laboratory Accessioning Number (LAN) at random, and completing any additional data documentation absent from an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drug substances. Although Screening is cost-efficient in eliminating the possibility of drug use in most samples, any positive indication necessitates confirmation to be valid in legal proceedings. Samples with a presumptive positive result during Screening necessitate further confirmation.

For samples showing a presumptive positive in the Screening phase, additional hair is selected from the original sample and prepped for Extraction. In this phase, drugs are extracted from hair at a notably reduced concentration relative to other methods (e.g., urine or oral fluid), contributing to the complexity of performing hair drug screening.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. The entire laboratory activity from Accessioning to Confirmation is scrutinized in line with the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug screening can ascertain drug use extending to 90 days, whereas urine testing offers a narrower detection period.
• Challenging to deceive: Deceptive practices in hair drug testing are exceedingly difficult, ensuring higher accuracy.
• Reflects historical usage: It traces drug use patterns over time, rather than merely recent consumption.

Limitations:

• Inability to identify recent use: Drugs become evident in hair after approximately 5-7 days.
• Expense: Hair drug testing is usually costlier compared to other testing approaches.
• Result variability: Elements such as hair color and individual discrepancies in hair growth impact drug metabolite concentration levels within the hair.

Note: Although frequently described as "hair follicle tests", this analysis evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
