Hair Follicle Drug Testing - Preston, MD

What it is, How it works

Hair analysis is now recognized as a potent means for identifying alcohol and drug use. Hair captures a timeline of alcohol and other drugs by embedding biomarkers within the fibers of the developing hair. Hair collected near the scalp can indicate alcohol and other drug use for around a 3-month period. Hair is easy to collect, tough to tamper with, and straightforward to transport.

A sample measuring 1.5 inches, comprising about 200 hair strands (comparable to a #2 pencil), taken closest to the scalp yields 100mg of hair, which is the prime sample size for testing and verification. For EtG, add-ons, and/or testing beyond 10 panels, a specimen weighing 150mg is suggested. We advise using a jeweler’s scale for weighing the sample. If scalp hair is inaccessible, an equivalent amount of body hair is acceptable. By head hair, we specifically mean scalp hair, while body hair refers to other types (facial, underarm, etc.).

Process Overview

The core steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails introducing a sample into a lab’s system, ensuring the sample is sealed and dispatched correctly, assigning it a random LAN (Laboratory Accessioning Number), and inputting any extra data not covered by an electronic chain of custody process.

Screening provides an initial swift evaluation for substances of abuse. Screening is an economical approach to dismissing drug use in most samples; however, any positive results must be confirmed for court acceptance. Presumptive positives in Screening demand secondary confirmation.

Should a sample yield a presumptive positive in Screening, more hair is extracted from the initial sample for preparation under Extraction. Here, substances are isolated from hair at a considerably lower concentration compared to other techniques (e.g., urine or oral fluid), which makes hair drug screening a complex technique.

Confirmation of any positive result from Screening is conducted utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation when necessary. The full lab process, covering Accessioning through to Confirmation, adheres to the evaluations under CAP (College of American Pathologists) Hair guidelines and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests which have a more limited detection span.
• Challenging to manipulate: Hair drug tests are challenging to compromise, enhancing result accuracy.
• Tracks historical data: It delivers a drug use trend over time, not merely the latest usage.

Limitations:

• Unable to detect immediate use: Detection in hair takes roughly 5-7 days post-drug use.
• Expense: Hair drug tests tend to be costlier than other drug testing alternatives.
• Outcome variability: Elements like hair color and individual hair growth rates can influence drug metabolite concentration in the hair.

Note: Although termed "hair follicle tests", the analysis targets the hair strand, not the scalp's hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Superior Substance Detection in Preston, MD underscores why hair follicle testing outperforms urine testing.
