Hair Follicle Drug Testing - Cedarville, MD

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol usage. It offers an extensive historical record of alcohol and drug consumption by embedding biomarkers within the fibers of the hair as it develops. When hair is collected near the scalp, it can reveal drug use over a detection span of roughly three months. Hair collection is straightforward, challenging to tamper with, and convenient for shipment.

A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp, yields 100mg, which is the optimal quantity for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, a sample of 150mg is advised. It is suggested to weigh the sample using a jeweler's scale. Should scalp hair be inaccessible, an equivalent quantity of body hair might be used. When discussing head hair, it specifically pertains to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

Four primary steps constitute the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a laboratory system. This step ensures the sample's seal and shipment integrity, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not managed by an electronic chain of custody system.

Screening entails a preliminary check for potentially abusive drugs. While Screening is economical for dismissing drug use in most samples, a positive outcome must be verified to hold up in court. Any samples indicated as positive in Screening require a confirmatory secondary analysis.

If Screening indicates a presumptive positive, additional hair is extracted from the primary sample for the Extraction process. This step involves extracting drugs from hair at substantially lower concentrations than other methods (e.g., urine or oral fluid), which accounts for the complexity of performing hair drug screening.

Positive results from the screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is overseen under the CAP (College of American Pathologists) Hair designation and aligns with ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use for a duration up to 90 days, unlike urine tests that offer a shorter detection period.
• High resistance to tampering: It's notably challenging to manipulate a hair drug test, thereby enhancing result accuracy.
• Tracks historical usage: Offers a chronological pattern of drug consumption over time, beyond recent usage.

Limitations:

• Inability to identify recent consumption: Drugs require approximately 5-7 days to become traceable in hair.
• Expense: Hair drug tests generally incur higher costs compared to alternative testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can impact the concentration of drug metabolites in hair.

Note: Commonly termed "hair follicle tests", the analysis is conducted on the hair strands, not on the hair follicles beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Cedarville, MD, lies in its superior detection and reliability.
