Hair Follicle Drug Testing - Waterloo, MD

What it is, How it works

Utilizing hair samples has become recognized as a significant method in detecting substance and alcohol consumption. Hair can capture a substantial historical record of drug and alcohol use by embedding biomarkers in the hair strand as it grows. When hair is clipped close to the skin surface, it offers a detection period of around three months for substance and alcohol presence. Obtaining hair samples is straightforward, tampering is relatively complicated, and sending it for analysis is convenient.

A 1.5-inch segment comprising roughly 200 hairs (approximately the width of a #2 pencil) near the scalp will yield 100mg, optimal for examination and validation. For EtG, supplemental, and/or beyond 10-panel assessments, 150mg of the specimen is advised. It's suggested to weigh the specimen on a jeweler’s scale. If scalp hair cannot be collected, a similar quantity of body hair is an alternative. When discussing head hair, it refers solely to scalp hair. Body hair encompasses other types (facial, axillary, etc.).

Process Overview

The principal procedures in lab processing of a substance test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the primary integration of a sample into the lab's framework. This step verifies the sample's seal and shipping integrity, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data input beyond what's provided by an electronic chain of custody system.

Screening involves an initial rapid evaluation for substances of misuse. Though Screening is cost-efficient for largely determining non-use in samples, a positive screen necessitates confirmation for legal admissibility. Samples provisionally testing positive in Screening are required to undergo further confirmation.

When a sample tests provisionally positive during the Screening phase, additional hair is extracted from the primary specimen and conditioned for Extraction. Here, substances are isolated from hair at significantly lower concentrations than in urine or oral fluid methodologies, illustrating the complexity of performing hair drug assessments.

Confirmation of any positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing provisionally positive undergo necessary washing pre-confirmation. The complete laboratory protocol from Accessioning to Confirmation is monitored following CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Benefits of hair drug analysis:

• Extensive detection duration: Hair drug assessments can reveal substance use up to 90 days, as opposed to urine tests with a briefer detection span.
• Challenging to counterfeit: Cheating a hair drug test proves highly challenging, leading to more precise results.
• Offers historical insight: It supplies a sequence of substance utilization over time, beyond just recent activity.

Drawbacks:

• Incapable of detecting recent consumption: It requires about 5-7 days for substances to become traceable in hair.
• Expense: Hair drug assessments generally incur higher costs than other testing techniques.
• Result variations: Factors, including hair color and individual hair growth differences, can influence drug metabolite concentration in hair.

Note: Frequently termed as "hair follicle tests", the analysis actually examines the hair strand, not the follicle beneath the scalp.
