Hair Follicle Drug Testing - Fort Ritchie, MD

What it is, How it works

Hair analysis is increasingly utilized as an effective means for identifying drug and alcohol consumption. Hair offers an extended historical record of substance use by embedding biomarkers within its growing fibers. When hair is sampled near the scalp, it can offer a detection window of up to three months for substances like alcohol and other drugs. The collection of hair is straightforward, moderately resistant to tampering, and convenient to transport.

An ideal hair sample consists of a 1.5-inch length of about 200 strands (roughly the diameter of a #2 pencil) taken closest to the scalp, yielding 100mg, suitable for initial screening and verification processes. For EtG extensions and tests exceeding 10-panel levels, a 150mg sample is advised. Using a jeweler’s scale for measurement is recommended. In cases where scalp hair cannot be obtained, equivalent amounts of body hair may be used. The term head hair specifically refers to scalp hair, while body hair encompasses various other types (such as facial or underarm hair).

Process Overview

The laboratory procedure for processing a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes an initial intake into the laboratory system, ensuring proper sealing and shipment, assigning it a LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody.

Screening efficiently checks for substance abuse, although it is a budget-friendly method to eliminate drug use in most samples, positive results require additional confirmation for legal admissibility. Positive screens in Screening necessitate a follow-up confirmation step.

If the Screening phase flags a sample as presumptively positive, it leads to additional hair being taken from the original sample for Extraction. At this stage, substances are separated from hair at a lower concentration than in other methods (such as urine or oral fluid), making hair drug screening the most complex to execute.

To confirm any positive Screening outcome, methods like GC/MS, GC/MS/MS, or LC/MS/MS are used. All presumptive positive samples undergo requisite washing before confirmation. The entire process across Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests are capable of identifying substance use for up to 90 days, as opposed to urine tests which have a briefer detection range.
• Resistance to tampering: Manipulating a hair drug test is challenging, resulting in more reliable results.
• Chronological usage insights: The test showcases a pattern of drug consumption over time, not just recent usage.

Limitations:

• Inability to detect immediately after use: Detection of substances in hair takes approximately 5-7 days.
• Expense: Typically, hair drug tests are pricier than other testing methods.
• Potential for variable outcomes: Elements such as hair color and individual differences in hair growth can influence drug metabolite levels in hair samples.

Note: Although often termed "hair follicle tests", the examination is performed on the hair strand itself, not the follicle located beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Fort Ritchie, MD, hair follicle testing proves superior to traditional urine tests. Hair tests offer enhanced detection accuracy, identifying substance use over a more extended period.
