Hair Follicle Drug Testing - Belle, WV

What it is, How it works

Hair testing is regarded as an effective means to detect drug and alcohol consumption. The fibers in a hair strand capture biomarkers, reflecting a long-term history of substance use. When obtained near the scalp, hair can reflect activity over a period of up to three months for alcohol and other drugs. It is easy to collect, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to a #2 pencil thickness) near the scalp, yields 100mg—ideal for comprehensive testing. For EtG, additional tests, or panels exceeding ten, a 150mg specimen is advisable. Employing a jeweler’s scale to weigh the specimen is recommended. In the absence of scalp hair, equivalent body hair may be utilized. When discussing head hair, it pertains solely to scalp hair; body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The lab procedures for processing a drug test result involve four significant stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary step where the sample is integrated into the laboratory's system. This process confirms the sample's correct sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry missing from an electronic chain of custody system.

During Screening, the sample undergoes an initial examination for drug presence. While the method is cost-effective, samples that screen positive require confirmation to be valid in legal contexts. Thus, presumptively positive samples necessitate secondary confirmation.

When a sample tests presumptively positive at the Screening stage, additional hair is taken from the sample for Extraction. Here, drugs are isolated at lower concentrations than found in other test types (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.

Confirmation for positive screening outcomes is performed via technologies like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing if necessary. The entire lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests monitor drug usage for as long as 90 days, whereas urine tests have a more limited window.
• Harder to manipulate: Hair drug testing is more reliable as it is difficult to alter the results.
• Tracks usage history: It reveals patterns of substance use across an extended period, not merely immediate consumption.

Limitations:

• Cannot capture recent usage: Drugs become detectable in hair approximately 5-7 days following use.
• Expense: Hair drug testing typically incurs higher costs than other testing options.
• Result variability: Elements like hair color and individual variations in growth may influence metabolite concentrations.

Note: Although commonly called "hair follicle tests", this test examines the hair strand and not the below-scalp follicle.
