Hair Follicle Drug Testing - Derita, NC

What it is, How it works

Hair analysis is increasingly perceived as an effective method for identifying drug and alcohol consumption. Hair provides an extended timeline of substance use by embedding biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can offer a detection period extending up to about 3 months for alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hairs (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, an optimal sample for both initial screening and confirmation. For EtG, additional tests, and/or panels above ten, a 150mg sample is advised. Usage of a jeweler’s scale is recommended for weighing the sample. If scalp hair is not available, a comparable amount of body hair can be collected. References to head hair pertain solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The four primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into a lab’s system. This process verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and handles any additional data entry not managed by an electronic chain of custody system.

Screening consists of an initial rapid assessment for drugs of abuse. Although Screening is a cost-effective method for eliminating drug usage in most samples, a positive result requires confirmation for legal acceptability. Samples preliminarily positive in Screening necessitate secondary confirmation.

If a sample is preliminarily positive during the Screening phase, additional hair is extracted from the primary specimen and made ready for Extraction. This phase extracts drugs from hair at significantly lower concentrations than alternative methodologies (like urine or oral fluid), which is why hair drug testing is the most challenging methodology to execute.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating a presumptive positive are cleaned as required before confirmation. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, contrary to urine tests which feature a shorter detection window.
• Hard to deceive: It is notably challenging to deceive a hair drug test, enhancing result accuracy.
• Offers historical insight: It offers insight into a pattern of drug use over time, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: It takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically costlier than other drug testing techniques.
• Result variations: Elements like hair color and individual hair growth rates can influence the drug metabolite concentration in hair.

Note: Commonly referred to as "hair follicle tests", the test itself analyzes the hair strand, not the follicle residing beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Derita, NC, hair follicle testing is superior to traditional urine tests due to its enhanced detection precision and reliability.
