Hair Follicle Drug Testing - Kinston, NC

What it is, How it works

Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair offers an extended history of substance intake by embedding biomarkers within the fibers of the hair strand. When gathered near the scalp, hair can reveal up to roughly a three-month detection window for alcohol and drugs. Hair is easy to gather, somewhat challenging to tamper with, and straightforward to transport.

A 1.5-inch section containing about 200 hair strands (around the size of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the specimen is preferred. We advise weighing the specimen on a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair may be collected. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The four key stages in the laboratory handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a sample into a laboratory’s system. This checks that the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not offered by an electronic chain of custody system.

Screening entails a preliminary swift examination for drugs of abuse. Although Screening is an economical approach to rule out drug usage in most samples, a positive result requires confirmation to be admissible in court. Any samples with presumptive positives in Screening need a secondary confirmation.

If a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen and prepped for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), thus making hair drug screening the most complex methodology to execute.

Confirmation of any positive screening result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The end-to-end laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection timeframe: Hair drug tests can trace drug usage for up to 90 days, unlike urine tests which offer a shorter detection window.
• Hard to falsify: It is notably difficult to cheat a hair drug test, resulting in more reliable outcomes.
• Offers historical insights: It can reveal a pattern of drug use over a duration, rather than immediate use only.

Limitations:

• Cannot detect initial use: Approximately 5-7 days are needed for drugs to become detectable in hair.
• Cost: Hair drug tests generally incur higher expenses compared to other drug testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: While commonly termed "hair follicle tests", the examination itself targets the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Kinston, NC, hair follicle testing surpasses traditional urine tests in several ways.
