Hair Follicle Drug Testing - Toddville, MD

What it is, How it works

The utilization of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug presence by encasing biomarkers within the strands of growing hair. When hair is sampled near the scalp, it can reveal drug or alcohol presence for up to around a 3-month timeframe. The collection process is straightforward, relatively tamper-resistant, and easily transportable.

A sample of 1.5 inches with roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for analysis. For EtG, additional testing, and/or tests surpassing 10 panels, 150mg of hair is advisable. It's recommended to use a jeweler’s scale for measuring the sample. If head hair is unavailable, a similar amount of body hair can be utilized. When mentioning head hair, it pertains solely to scalp hair. Body hair pertains to hair from other areas (such as facial, axillary, etc.).

Process Overview

The four primary phases in lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the first step of processing a sample into a lab system. This step includes confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody system.

Screening serves as a preliminary assessment for the presence of drugs. Although screening is an economical method to exclude drug usage in the majority of samples, confirmed results are necessary for court admissibility. Samples presumed positive during Screening demand subsequent confirmation.

Should a sample test presumptively positive at the Screening phase, a greater amount of hair is extracted from the starting sample and readied for Extraction. During this phase, drugs are removed from hair, resulting in a lesser concentration than other techniques (e.g., urine or oral fluid), which is why hair drug screening is among the toughest methodologies to execute.

The confirmation of any positive screening result is achieved using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive specimens undergo a wash before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection duration: Hair drug tests can pinpoint drug usage for up to 90 days, as opposed to urine tests which have a briefer detection span.
• Harder to manipulate: Hair drug tests are challenging to distort, ensuring more reliable results.
• Historical pattern data: Hair testing offers insight into drug usage patterns over time, not only recent use.

Limitations:

• Inability to detect immediate usage: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests are typically pricier than other testing methods.
• Result variability: Factors such as hair color and personal hair growth variations can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis actually examines the hair strand rather than the follicle underneath the scalp.
