Hair Follicle Drug Testing - Walkertown, NC

What it is, How it works

Hair analysis is now recognized as an effective method for detecting drug and alcohol usage. The growth of hair strands allows for the encapsulation of biomarkers, offering a prolonged history of substance consumption. When hair is gathered near the scalp, it can reveal up to a roughly 3-month period of substance detection. It's straightforward to collect, hard to alter, and simple to transport.

A sample of 1.5 inches, comprising approximately 200 hair strands (akin to the thickness of a #2 pencil) close to the scalp, yields 100mg of hair, which is ideal for both screening and confirmation. For comprehensive evaluations like EtG, add-ons, or tests beyond 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale to weigh the sample is suggested. If head hair isn’t available, an equivalent amount of body hair can be used. "Head hair" refers strictly to scalp hair, while "body hair" encompasses all other types, including facial and axillary.

Process Overview

The drug test result processing in a lab involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails initially inputting a sample into a lab's database. This step verifies that the sample is adequately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and fills in any missing data not covered by the electronic chain of custody system.

Screening performs a preliminary check for drug presence. Although Screening serves as an efficient means to exclude drug use in most samples, a subsequent confirmation is necessary for positive screens to hold up in legal contexts. Samples that test positive initially must undergo further confirmation.

If the Screening indicates a potential positive, additional hair is extracted from the initial sample for the Extraction process. During this phase, drugs are extracted from hair at notably lower concentrations compared to other methods such as urine or oral fluids, emphasizing the complexity of hair drug screening.

The positive results from screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples deemed potentially positive undergo a washing process before confirmation as needed. The complete lab cycle from Accessioning through Confirmation is checked under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use up to 90 days compared to urine testing, which has a more limited detection timeframe.
• High integrity: Cheating a hair drug test is exceptionally tough, ensuring reliable results.
• Historical pattern identification: It can map drug use behavior over time, unlike recent usage tests.

Limitations:

• Delayed detection of recent usage: It requires 5-7 days before drugs become traceable in hair.
• Price: Generally, hair drug testing incurs higher costs than alternative testing methods.
• Result variability: Hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Commonly misnamed as "hair follicle tests", the actual analysis is performed on the hair strand, not on the follicle located beneath the scalp
