Hair Follicle Drug Testing - Greensburg, MD

What it is, How it works

Utilizing hair as a testing medium has emerged as an effective means for identifying drug and alcohol consumption. The hair encapsulates a historical account of substance use by embedding markers within its growing fibers. When sourced from the scalp, hair testing can provide a detection timeframe extending up to three months for drugs and alcohol. The process of collecting hair samples is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches in length, composed of approximately 200 hair strands (comparable to a #2 pencil's thickness) near the scalp, can yield about 100mg of hair, which is optimal for both initial screening and confirmation. For EtG add-ons or tests beyond 10 panels, a specimen weighing 150mg is recommended. It is advisable to measure the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be obtained. Head hair specifically refers to scalp hair, whereas body hair encompasses other types like facial and axillary hair.

Process Overview

The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is registered into the lab's system. This step includes checking the proper sealing and shipment of the sample, assigning a Laboratory Accessioning Number (LAN), and entering any extra information not covered by an electronic chain of custody.

Screening provides an initial assessment for detecting drug abuse. It is a cost-efficient method to eliminate drug use in most samples; however, samples that test positive during this stage require confirmation for legal validity. Samples showing presumptive positivity during Screening must undergo a secondary confirmation process.

If Screening suggests a positive result, additional hair is extracted from the given sample and prepared for the Extraction process. This process involves extracting drugs from hair, albeit at a much lower concentration compared to methods like urine or oral fluid tests, which is why hair drugs screening is considered the most challenging technique.

Confirmation of positive screening outcomes is carried out via techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed appropriately before confirmation. The comprehensive lab process from Accessioning through to Confirmation is conducted in alignment with the CAP (College of American Pathologists) Hair criteria and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drugs in the system for as long as 90 days, unlike urine tests that offer a shorter detection period.
• Hard to manipulate: Cheating on hair drug tests is considerably challenging, ensuring more precise results.
• Provides usage patterns: It gives insights into the pattern of drug consumption over time rather than just recent usage.

Limitations:

• Inability to identify recent usage: It typically takes 5-7 days for drugs to manifest in hair samples.
• Expense: Generally, hair drug testing is more costly compared to other drug testing methods.
• Result variability: Aspects like hair color and differences in individual hair growth can influence drug metabolite concentration in hair.

Note: While commonly termed as "hair follicle tests," the analysis is conducted on the hair strand itself, not the follicle within the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Greensburg, MD, hair follicle testing shows superior benefits compared to urine tests. Its higher accuracy and reliability stem from its longer detection window and the ability to reveal consistent substance use.
