Hair Follicle Drug Testing - Clover, VA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term indicator of alcohol and drug usage by embedding biomarkers in the hair strand's fibers as it grows. When collected close to the scalp, hair provides a detection window of up to approximately 3 months for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch sample of around 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional testing, and tests over 10 panels, 150mg of hair is suggested. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair may be collected. "Head hair" specifically refers to scalp hair, while "body hair" denotes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial sample processing into the laboratory’s system, ensuring the sample was correctly sealed and shipped, assigning a Laboratory Accessioning Number (LAN), and entering any extra information not included by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. While it's a cost-effective method to exclude drug use in most samples, any positive screen needs confirmation for legal admissibility. Samples that presumptively test positive in Screening necessitate further confirmation.

Should a sample test positive in the Screening stage, more hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptively positive samples are cleansed before confirmation as required. Both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation oversee the entire laboratory process from Accessioning to Confirmation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests, which have a shorter detection period.
• Resilience against tampering: Cheating a hair drug test is highly challenging, enhancing the test's accuracy.
• Tracks historical usage: It reveals a pattern of drug usage over time, not merely recent use.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests often incur higher costs than other drug testing methods.
• Result variations: Factors such as hair color and growth variations can influence drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests," the actual analysis examines the hair strand, not the follicle below the scalp
