Hair Follicle Drug Testing - Clarkton, NC

What it is, How it works

Hair testing is recognized as a significant method for identifying drug and alcohol usage. Hair captures a comprehensive record of alcohol and other drugs by embedding biomarkers within the growing hair fibers. When acquired near the scalp, hair can reveal a detection period of up to nearly 3 months for alcohol and other substances. Hair is straightforward to collect, challenging to tamper with, and simple to transport.

A sample of 1.5 inches consisting of around 200 hair strands (approximately the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is suggested. We advise measuring the sample using a jeweler's scale. If scalp hair is absent, a comparable amount of body hair can be utilized. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

There are four primary stages in processing a drug test result in the laboratory: Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the initial integration of a sample into a lab's system. This step ensures that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not captured by an electronic chain of custody system.

Screening entails an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient method for eliminating drug use in most samples, a positive finding must be confirmed for legal validity. Samples showing a presumptive positive in Screening require a secondary verification.

Should a sample test positive at the Screening phase, additional hair is obtained from the initial sample and set up for Extraction. In this phase, drugs are retrieved from the hair at a concentration lower than other methods (such as urine or oral fluid), making hair drug screening the most complex methodology to execute.

Verification of any positive result from Screening is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes are cleansed before confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug use for up to 90 days, compared with urine tests which have a shorter timeframe.
• Hard to circumvent: It is extremely difficult to evade a hair drug test, leading to more precise results.
• Offers historical insight: It provides a record of drug usage over a duration, not just current use.

Limitations:

• Inability to detect recent use: It takes nearly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically more costly than other drug testing techniques.
• Outcome variances: Elements such as hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: Although commonly termed as "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
