Hair Follicle Drug Testing - Glenwood, NC

What it is, How it works

The application of hair testing is increasingly recognized as an effective method for the identification of drug and alcohol consumption. Hair can chronicle extended histories of substance use by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair samples can offer a detection horizon of roughly 3 months for alcohol and other substances. Hair is straightforward to collect, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches consisting of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirmation purposes. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. We advise using a jeweler's scale for weighing the sample. If hair from the scalp cannot be obtained, an equivalent amount of body hair may be used. By head hair, we mean scalp hair only, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The lab procedures involved in processing a drug test result encompass four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into the laboratory system. This process involves confirming the sample was properly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and fulfilling any supplemental data entry not addressed by an electronic chain of custody mechanism.

Screening is a preliminary evaluation for the presence of drugs. While it serves as a cost-efficient means to rule out drug use in most samples, a positive screening result necessitates further confirmation to be recognized legally. Samples yielding presumptive positive results in Screening must undergo additional verification.

Should a sample show presumptive positivity during Screening, additional hair is extracted from the original sample and prepared for Extraction. In this process, drugs are isolated from the hair at significantly lower concentrations than in other testing methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positively screened result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleansed using washing techniques before confirmation when needed. The comprehensive laboratory workflow from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) guidelines on Hair designation and the standards for accreditation in ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use up to 90 days, whereas urine tests have a more limited detection span.
• Resistance to tampering: Cheating a hair drug test is notably challenging, enhancing result accuracy.
• Insights into substance use patterns: It reveals drug consumption trends over extended periods, beyond just recent use.

Limitations:

• Inability to detect recent use: Drugs typically take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs than alternative drug testing methods.
• Result variability: Variables such as hair color and individual hair growth deviations can influence drug metabolite concentrations in the hair.

Note: Commonly dubbed "hair follicle tests", the actual analysis is performed on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Glenwood, NC, the advantages of hair follicle testing over urine testing are evident. Hair testing offers superior detection accuracy and a much longer detection window, making it a more reliable choice.
