Hair Follicle Drug Testing - Wilderness, VA

What it is, How it works

The use of hair testing is increasingly recognized as an effective approach for identifying drug and alcohol consumption. Within the hair strands, biomarkers become embedded, capturing a prolonged record of usage. When hair samples are obtained near the scalp, they offer a detection timeframe extending up to roughly three months for alcohol and other substances. Hair collection is straightforward, not easily tampered with, and convenient for transport.

A sample measuring 1.5 inches consisting of approximately 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect quantity for both screening and verification. For tests involving EtG, additional tests, or panels exceeding 10, a specimen weighing 150mg is advised. Using a jeweler's scale is suggested for measuring the sample weight. If scalp hair cannot be obtained, an equal quantity of body hair may be collected. The term "head hair" pertains specifically to scalp hair, whereas "body hair" includes all other varieties (such as facial or axillary).

Process Overview

The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial stage of integrating a sample into the lab's system. This stage involves ensuring the sample's correct sealing and transport, generating a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent from the electronic chain of custody process.

Screening serves as a preliminary check to identify drugs of abuse. While it's an economical approach to dismiss drug usage in most samples, any positive outcome requires confirmation to stand in a legal context. Samples yielding presumptively positive results during Screening necessitate further confirmation.

When a sample indicates a presumptive positive at the Screening phase, additional hair is extracted from the initial specimen for the Extraction process. Drugs are extracted from hair at notably lower concentrations compared to other methods, like urine or oral fluid, establishing hair drug screening as a particularly challenging approach.

Confirmation of positive screening results is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if required. The entire laboratory workflow from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests provide evidence of substance use for up to 90 days, unlike urine tests with a shorter detection period.
• Hard to deceive: Cheating a hair drug test is exceedingly difficult, thereby enhancing accuracy.
• Offers historical patterns: It establishes a timeline of drug consumption over time, rather than simply recent use.

Limitations:

• Incapacity to detect recent usage: It takes about 5-7 days for drugs to become detectable in hair.
• Higher cost: Hair drug tests tend to be costlier compared to other testing methods.
• Result variability: Drug metabolite levels in hair may be influenced by factors such as hair color and individual hair growth variations.

Note: Although often called "hair follicle tests," the test analyzes the strand of hair, not the follicle beneath the scalp
