Hair Follicle Drug Testing - West Point, VA

What it is, How it works

Hair testing is increasingly recognized as a robust method for determining drug and alcohol consumption. By embedding biomarkers within the fibers of the growing hair strand, hair furnishes a comprehensive historical record of alcohol and drug usage. When procured near the scalp, hair can offer an estimated detection period of up to three months for alcohol and drugs. Collection is straightforward, challenging to tamper with, and convenient for shipping.

A 1.5-inch sample of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, an optimal amount for screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, a quantity of 150mg is advisable. The specimen's weight should be verified on a jeweler’s scale. In cases where scalp hair isn't available, an equivalent amount of body hair can be substituted. The term "head hair" specifically denotes scalp hair. "Body hair" encompasses all other hair types (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug test result comprises four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory's framework. This phase involves ensuring proper sealing and dispatch of the sample, generating a random LAN (Laboratory Accessioning Number), and filling in any supplemental data not covered by an electronic chain of custody system.

Screening constitutes a preliminary evaluation for drug presence. As a cost-efficient means of excluding drug use in most samples, Screening is efficacious; however, a positive result necessitates confirmation for legal admissibility. Samples yielding presumptive positives in Screening require secondary verification.

Should a sample yield a presumptive positive during Screening, additional hair is extracted from the original specimen and processed for Extraction. In this stage, drugs are withdrawn from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), which renders hair drug testing the most intricate methodology.

Verification of any positive screening outcomes is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptively positive samples undergo washing as needed. The comprehensive lab process, spanning from Accessioning to Confirmation, complies with the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which exhibit a more limited detection period.
• Cheat-proof: Hair drug tests are notably challenging to outsmart, enhancing result accuracy.
• Chronological data provision: They reveal a pattern of drug use over time rather than merely recent consumption.

Limitations:

• Inability to identify recent use: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs compared to alternative drug testing methods.
• Result variability: Elements such as hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although frequently termed "hair follicle tests," the evaluation itself focuses on the hair strand, not the follicle situated beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In West Point, VA, hair follicle testing is preferred over traditional urine tests for its superior detection capabilities. Hair tests offer accurate insights, minimizing the chances of cheating, which is a common concern with urine tests. Employers and officials benefit from reliable results, supporting zero-tolerance policies effectively.

Compared to urine tests that detect recent use, hair testing excels in showing prolonged use patterns, presenting a comprehensive substance profile. Its accuracy in revealing an extended history of use makes it the preferred choice for thorough evaluations.
