Hair Follicle Drug Testing - Harrellsville, NC

What it is, How it works

Hair testing has emerged as a formidable method for identifying drug and alcohol consumption. Hair can capture a lasting record of substance usage by locking biomarkers within the strands. When collected near the scalp, hair offers a detection window of up to roughly 3 months for such substances. It’s easy to gather, relatively resistant to tampering, and simple to transport.

A sample measuring 1.5 inches of roughly 200 hair strands (around the diameter of a #2 pencil) next to the scalp is sufficient to yield 100mg of hair, which is optimal for both screening and confirmation. For EtG, extra components, or tests exceeding 10 panels, a 150mg specimen is advised. We suggest verifying the sample weight with a jeweler’s scale. If scalp hair is not an option, an equal volume of body hair is acceptable. By head hair, we specifically mean scalp hair, whereas body hair encompasses all other types (facial, armpit, etc.).

Process Overview

The primary stages in the lab handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially registering a sample in a laboratory’s system. This includes checking if the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any additional data requirements not supported by an electronic chain of custody system.

Screening is a preliminary rapid assessment for the presence of drugs. It’s a budget-friendly method to disregard drug presence in most cases, however, a positive result in Screening needs validation to be defensible in legal proceedings. Any samples that test presumptively positive during Screening must undergo further confirmation.

For samples presumptively positive at the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at much lower concentrations compared to other methods (e.g., urine or saliva), which makes hair drug screening the most challenging method to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptively positive samples are cleansed prior to confirmation as necessary. The entire lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug tests can identify drug consumption for up to 90 days, whereas urine tests have a shorter time frame.
• Challenging to manipulate: It’s highly challenging to alter hair drug test results, hence providing more reliable outcomes.
• Yields historical data: It offers insights into drug use trends over time, rather than just recent usage.

Limitations:

• Incapable of detecting immediate use: It requires about 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug tests tend to cost more than alternate drug testing techniques.
• Result variability: Elements such as hair color and personal differences in hair growth might influence drug metabolite levels in hair.

Note: While commonly known as "hair follicle tests", the analysis targets the hair strand, not the hair follicle beneath the scalp
