Hair Follicle Drug Testing - Friendship Heights Village, MD

What it is, How it works

Hair testing has emerged as a robust technique for identifying drug and alcohol consumption. Hair retains a detailed record of alcohol and drug intake by embedding biomarkers within its fibers. When collected close to the scalp, hair can reveal a detection timeframe of up to 3 months for alcohol and other drugs. Gathering the sample is straightforward, it’s fairly resistant to tampering, and easy to transport.

A 1.5-inch lock of around 200 hair strands (roughly akin to a #2 pencil) closest to the scalp delivers 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, add-ons, and/or examinations exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale to measure the sample weight is recommended. If scalp hair isn’t accessible, a comparable amount of body hair can be used. References to head hair indicate only scalp hair. Body hair refers to any other types (such as facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial processing of the sample into a laboratory's system. This step encompasses verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody system.

Screening consists of an initial check for abused drugs. Although Screening offers a cost-effective approach for ruling out drug use in most samples, a positive screen requires confirmation for admissibility in court. Any samples with a presumptive positive result during Screening must undergo a secondary validation.

Should a specimen be presumptively positive at the Screening phase, additional hair is obtained from the initial sample and prepared for Extraction. During this phase, drugs are isolated from hair at a much lower concentration level than with other methods (e.g., urine or oral fluid), which is why hair drug screening poses the greatest methodological challenge.

Confirmation for any positive screen outcome is executed via GC/MS, GC/MS/MS or LC/MS/MS. Every presumptive positive sample is cleansed as required before confirmation. The entire laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for as long as 90 days, unlike urine tests which have a reduced detection duration.
• Hard to manipulate: Manipulating a hair drug test is quite challenging, thus yielding more reliable outcomes.
• Delivers historical insight: It offers a timeline of drug consumption over a specified period, rather than just recent usage.

Limitations:

• Inability to detect recent use: It usually takes around 5-7 days for drugs to be perceptible in hair.
• Expense: Hair drug tests often come at a higher cost than other drug testing methodologies.
• Result variances: Variables like hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly referred to as "hair follicle tests", the actual test examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Friendship Heights Village, MD, hair follicle testing surpasses urine testing as it boasts superior detection accuracy and reliability.
