Hair Follicle Drug Testing - North Bethesda, MD

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting substance use involving drugs and alcohol. Hair strands offer an extended historical record of alcohol and other drugs, as they encapsulate biomarkers within the hair's fibers. When obtained adjacent to the scalp, the hair can offer a detection period of up to roughly 3 months for alcohol and various drugs. Hair collection is straightforward, less susceptible to tampering, and convenient for shipping.

A 1.5-inch segment consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) nearest the scalp yields 100mg, which is the ideal quantity for both screening and confirmation. For tests like EtG, add-ons, and those exceeding 10 panels, a specimen weight of 150mg is advisable. We suggest using a jeweler's scale to measure the sample. Should scalp hair be unavailable, an equivalent mass of body hair may be used. References to head hair pertain specifically to scalp hair, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The principal stages in lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab's system, which involves verifying proper sample sealing and shipping, allocating a unique LAN (Laboratory Accessioning Number), and completing any further data input absent in an electronic chain of custody system.

Screening consists of an initial swift examination for substance use. While Screening is a cost-efficient means to exclude drug use in most samples, a positive result necessitates confirmation for legal admissibility. Samples with presumptive positive outcomes in Screening mandate additional confirmation.

Upon a presumptive positive outcome in Screening, additional hair is taken from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

For any screening outcome that tests positive, Confirmation is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive undergo necessary cleaning prior to confirmation. The entire laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can discover drug use for up to 90 days, unlike urine tests which have a reduced detection period.
• Challenge to falsify: It is quite hard to falsify results of a hair drug test, enhancing accuracy.
• Delivers historical insight: It can demonstrate a timeline of substance use, not just recent intake.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair tests are typically pricier compared to other drug testing techniques.
• Result variability: Elements like hair color and personal hair growth differences can influence metabolite concentrations in hair.

Note: Although often labeled as "hair follicle tests", the analysis is conducted on the strand of hair, not the follicle beneath the scalp.
