Hair Follicle Drug Testing - Leitersburg, MD

What it is, How it works

The analysis of hair has emerged as a potent method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers within the fibers of the hair as it grows. Collected near the scalp, hair can provide a detection timeframe of up to about three months for alcohol and other drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient for transportation.

A 1.5-inch section containing roughly 200 hair strands (approximately the size of a #2 pencil) cut close to the scalp results in 100mg of hair, which is the perfect sample size for screening and confirmation. For testing involving EtG, additional panels, and/or those exceeding 10 panels, a sample weighing 150mg is advisable. Using a jeweler’s scale for measuring the sample is recommended. If no scalp hair is available, an equivalent portion of body hair can be used. The term head hair refers solely to scalp hair, while body hair covers all other types (facial, axillary, etc.).

Process Overview

The process of laboratory analysis for a drug test outcome involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial processing phase where a laboratory inputs a sample into their system. This stage includes checking that the sample was properly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not already handled by an automated chain of custody system.

Screening is an expedited initial evaluation for substance abuse. Although it serves as a budget-friendly measure to generally dismiss drug use in most samples, a positive screen must be validated to be legally acceptable. Samples that yield presumptive positive results during Screening require further confirmation.

Should a sample show presumptive positive results in the Screening phase, additional hair is extracted from the initial specimen and processed for Extraction. Here, drugs are separated from hair at much lower concentrations compared to other methods (such as urine or saliva), highlighting why hair drug testing presents a greater challenge compared to other methodologies.

Confirmation of a positive screening is executed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation, as necessary. Each step from Accessioning to Confirmation is scrutinized according to both CAP (College of American Pathologists) Hair protocols and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use for up to 90 days, contrasting with urine tests which offer a shorter detection span.
• Resistance to manipulation: Cheating on a hair drug test is highly challenging, thereby increasing accuracy.
• Insights on historical usage: It may reveal usage patterns over time, not solely recent consumption.

Limitations:

• Inability to detect recent usage: It takes about 5-7 days for drugs to become traceable within hair.
• Expense: Generally, hair drug tests come at a higher cost compared to other testing options.
• Result variation: Differences in hair color and individual growth rates can influence the levels of drug metabolites found in hair.

Note: Despite being commonly known as "hair follicle tests", the actual test is conducted on the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing

In Leitersburg, MD, hair follicle testing offers superior detection over traditional urine tests. Hair tests extend the detection window, spotting substance use for up to 90 days, while urine tests primarily capture recent drug use. Hair testing is less prone to manipulation, capturing a comprehensive history compared to urine's limited timeframe.

The reliability of hair tests stems from their method of utilizing protein in hair strands to lock in drug metabolites. This provides a stable testing medium, unlike urine tests susceptible to adulteration. These factors showcase the unmatched accuracy of hair follicle testing in drug and alcohol detection.
