Hair Follicle Drug Testing - Fairmount, MD

What it is, How it works

As an instrumental method for identifying drug and alcohol consumption, hair tests have gained prominence. Hair captures a historical record of alcohol and substance use by embedding biomarkers within the hair strand's fibers. When hair is sampled close to the scalp, it can reveal alcohol and drug presence for an approximate period of three months. The collection process is straightforward, the potential for tampering is minimal, and samples are easily transportable.

A 1.5-inch lock of around 200 hair strands, similar to the width of a #2 pencil and nearest the scalp, offers roughly 100mg—ideal for evaluation and validation. For EtG, add-ons, or assessments exceeding 10 panels, 150mg of hair is best. A jeweler’s scale is advised for measuring the hair sample. Should scalp hair be scarce, a comparable amount of body hair can be utilized. References to head hair pertain solely to scalp hair. All other types (facial, underarm, etc.) are categorized as body hair.

Process Overview

The primary stages in processing drug test outcomes in a lab include Sample Accessioning, Screening, Extraction, and Confirmation.

Accessioning is concerned with the incorporation of a sample into the laboratory's system. This step ensures the sample is secured and transported adequately, assigns a random LAN (Laboratory Accessioning Number), and manages any supplementary data entry beyond what is handled by an electronic chain of custody system.

Screening performs a preliminary check for drug presence. Although this method is economical for excluding drug usage across most samples, a positive result from Screening requires confirmation to be deemed valid in legal settings. All samples indicated as positive in this stage are subject to an additional verification.

If screening indicates a presumptive positive, further hair is extracted from the collected sample and readied for Extraction, wherein drugs are isolated from hair at concentrations markedly lesser than alternative methods (e.g., urine or saliva), underscoring the complexity of hair drug testing techniques.

Results indicating positivity during Screening undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples preliminarily indicated as positive undergo washing before confirmation, as necessary. The laboratory's comprehensive process from Accessioning to Confirmation is verified under both the CAP (College of American Pathologists) guidelines for Hair and adherence to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection duration: Capable of identifying drug consumption over approximately 90 days, unlike urine tests which are limited by a shorter detection period.
• Difficult to circumvent: Compromising hair drug tests is challenging, enhancing result fidelity.
• Chronological insight: Offers detailed usage patterns over time, rather than signaling only recent usage.

Limitations:

• Incapable of spotting recent consumption: Drugs only become detectable in hair after about 5-7 days.
• Expense: Generally, hair drug testing incurs higher costs than other methodologies.
• Result variability: Aspects such as hair pigmentation and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Despite the term "hair follicle tests" being common, the analysis targets the hair strand, not the follicle itself beneath the scalp.
