Hair Follicle Drug Testing - Huntingtown, MD

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. It offers a comprehensive historical record of drug use by embedding biomarkers within the strands of hair as they grow. When hair is gathered near the scalp, it can reveal drug and alcohol consumption history for up to three months. Collecting hair is straightforward, not easily tampered with, and convenient for transport.

An ideal screening sample consists of a 1.5-inch segment of around 200 hair strands (comparable to the girth of a #2 pencil) cut close to the scalp, yielding 100mg of hair. For EtG, extensive panel tests, or those exceeding 10, a sample of 150mg is advised. It is advisable to measure the specimen using a jeweler’s scale. Should scalp hair be lacking, an equivalent weight of body hair is suitable. References to head hair specifically mean the hair on the scalp, whereas body hair encompasses other types (facial, axillary, etc.).

Process Overview

The procedure in the lab for drug test analysis comprises four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into the lab’s system, ensuring proper sealing and shipment of the sample, assigning a LAN (Laboratory Accessioning Number) randomly, and entering any data not covered by electronic custody systems.

Screening offers an initial, rapid evaluation for drug indications. It provides a cost-efficient means to exclude drug use for most samples. However, to be valid in legal contexts, a positive screen must undergo confirmation. Any samples flagged as positive during Screening are subject to further confirmation.

Upon a presumptive positive at Screening, further hair is extracted from the initial sample for the Extraction phase. In this stage, drugs are isolated from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), which is a reason why hair testing presents unique challenges.

Confirmation of any positive screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positives undergo washing before confirmation as applicable. The entire process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair analysis identifies drug intake for a maximum of 90 days, surpassing urine tests which possess a shorter timeframe.
• Hard to manipulate: Altering results of a hair drug test proves exceptionally challenging, enhancing accuracy.
• Historical insight: It allows for monitoring use patterns over time, not just spotlighting immediate consumption.

Limitations:

• Inability to spot recent use: Drugs become traceable in hair roughly 5-7 days post-consumption.
• Expense: Hair testing commonly incurs higher costs than alternative drug analysis methods.
• Result variability: Various factors, such as hair color or individual growth rates, can impact drug metabolite presence in hair.

Note: Commonly mislabeled as "hair follicle tests", the testing actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Huntingtown, MD, hair follicle testing stands out against traditional urine tests, showcasing its superior accuracy and detection reliability. Hair testing captures a longer history of substance use, regardless of attempts to evade detection, ensuring comprehensive assessments.
