Hair Follicle Drug Testing - Chapel Hill, NC

What it is, How it works

Hair assessment is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair strands document an extended timeline of alcohol and drug use by incorporating biomarkers into their fibers during growth. When sampling near the scalp, hair can yield a detection period of roughly three months for alcohol and drugs. It is straightforward to obtain, somewhat challenging to tamper with, and convenient for shipping.

Collecting a 1.5-inch portion of approximately 200 hair strands (equivalent to the width of a #2 pencil) nearest the scalp will furnish 100mg of hair, the optimal quantity for assessment and verification. For EtG, supplementary, and/or analyses exceeding 10 panels, a 150mg sample is advised. We propose using a jeweler’s scale to weigh the sample. If hair from the scalp is lacking, a corresponding amount of body hair may be obtained. When we refer to head hair, it is specifically about scalp hair. Body hair pertains to other hair kinds (facial, axillary, etc.).

Process Overview

The primary stages involved in processing a drug test result within a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a lab’s system. This step ensures the sample was sealed and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not included in an electronic chain of custody.

Screening consists of a preliminary assessment for substances of misuse. Although Screening is an economical method to dismiss drug use in most samples, a positive initial test needs validation to be legally acceptable. Any samples preliminarily positive in Screening necessitate a subsequent confirmation.

Should a sample show a preliminary positive result in Screening, additional hair is drawn from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair in substantially lower concentrations compared to other systems (like urine or oral fluid), which makes hair drug analysis one of the most complex strategies to undertake.

Verification of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with preliminary positive outcomes are cleansed before confirmation as needed. The laboratory’s entire process, from Accessioning through Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair categorization and compliance with ISO / IEC 17025 standards.

Merits of hair drug testing:

• Extended detection period: Hair drug tests identify drug presence up to 90 days, as opposed to urine tests which offer a shorter detection span.
• Challenging to manipulate: It is highly challenging to manipulate a hair drug test, enhancing accuracy of outcomes.
• Delivers historical insights: It can depict a trajectory of drug consumption over time, not merely recent use.

Drawbacks:

• Incapable of detecting recent consumption: It requires around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than other drug testing approaches.
• Result variability: Elements like hair color and personal variations in hair growth can influence drug metabolite levels in the hair.

Note: Though frequently called "hair follicle tests", the assessment evaluates the hair strand, excluding the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Chapel Hill, NC offers a superior alternative to traditional urine tests. Compared to urine tests, hair tests provide a more reliable detection method. Hair samples can trace substance use back up to 90 days, surpassing the short detection window of urine tests.
