Hair Follicle Drug Testing - Quantico, MD

What it is, How it works

Hair analysis has emerged as a significant means for identifying drug and alcohol use. The hair shaft captures biomarkers along its fibers, offering a comprehensive history of alcohol and drugs. When cut near the scalp, hair samples may provide a detection window of up to 90 days for alcohol and other substances. The process of hair collection is straightforward, challenging to tamper with, and convenient for transport.

A strand sample, measuring 1.5 inches and comprising roughly 200 hairs (approximately the width of a #2 pencil) closest to the scalp, yields 100mg, which is ideal for both screening and confirmation. For EtG, supplementary tests, or panels exceeding 10, a 150mg sample is preferred. Utilizing a jeweler’s scale to weigh the specimen is advised. In cases where scalp hair is unavailable, body hair in equivalent amounts may be used. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other forms (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results entails four main steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, samples are initially processed within a lab’s system. This phase includes ensuring proper sealing and shipment of samples, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any supplemental data entry not offered by an electronic chain of custody system.

Screening offers a preliminary assessment for the presence of drugs. Though cost-effective for many samples, positive screens need confirmation to be valid in legal settings. Samples that screen positive presumptively must undergo further confirmation.

Presumptive positives in Screening lead to the extraction of additional hair from the primary specimen for Extraction. Here, drugs are isolated from hair at a lower concentration than in urine or oral fluid, marking hair drug testing as the most complex methodology available.

All positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. The complete procedure from Accessioning to Confirmation complies with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for as long as 90 days, surpassing the shorter detection periods of urine tests.
• High integrity: Hair drug tests are notably difficult to manipulate, enhancing result accuracy.
• Historical usage patterns: They disclose patterns of substance use over time, unlike tests that detect only recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Typically, hair drug tests incur higher costs than alternative testing methods.
• Result variability: Hair color and individual hair growth variations can affect metabolite concentrations.

Note: Despite being termed "hair follicle tests," the procedure analyzes the hair shaft, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Advantage of Hair Over Urine Testing
In the context of Quantico, MD, hair follicle testing offers unparalleled advantages compared to traditional urine tests.
