Hair Follicle Drug Testing - Washington Grove, MD

What it is, How it works

With hair testing acknowledged as a compelling method for detecting drug and alcohol use, it is valued for its ability to capture a history of substance intake through biomarkers ensnared within the hair strands. Cutting hair close to the scalp extends a detection span of nearly 3 months for drugs and alcohol. This collection method is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch portion containing around 200 hair strands (comparable to a #2 pencil’s thickness) close to the scalp yields 100mg of hair, the optimal quantity for screening and verification. For tests such as EtG, additional panels, or those exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is nonexistent, a comparable quantity of body hair can be utilized. References to head hair denote scalp hair exclusivity, whereas body hair encapsulates all other hair variations (including facial and axillary hair).

Process Overview

There are four pivotal phases in processing a laboratory drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is initially logged into the laboratory system. This phase verifies correct sample sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and completes any missing data not covered by an electronic custody system.

The Screening phase involves a brief preliminary examination for drug abuse. Screening is a cost-efficient strategy for dismissing drug use in most cases. However, a positive screen requires confirmation for legal admissibility. Samples that are presumptively positive in Screening necessitate further affirmation.

Should a sample be presumptively positive during Screening, additional hair is extracted from the first sample for preparation in the Extraction phase. Here, drug extraction occurs at much lower concentrations than other methods (such as urine or oral fluids), making hair drug screening the most challenging methodology.

Confirmation tactics for positive screening outcomes include GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all presumptive positive samples undergo a washing process if necessary. The lab procedure from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and holds accreditation per ISO/IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests reveal drug consumption for as long as 90 days, whereas urine tests boast a much shorter detection period.
• Cheating deterrent: Evading a hair drug test is highly challenging, enhancing the reliability of results.
• Chronic usage insight: Provides a substance use timeline, rather than merely recent consumption evidence.

Limitations:

• Cannot gauge recent use: Drugs become detectable in hair around 5-7 days post-use.
• Expense: Hair drug tests surpass other testing methods in cost.
• Outcome variability: Variables such as hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: While frequently termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
