Hair Follicle Drug Testing - Willards, MD

What it is, How it works

Hair analysis has become recognized as a potent method for identifying alcohol and drug use. It offers a comprehensive history of drug and alcohol consumption by capturing biomarkers within the strands of hair as they grow. When hair is taken from near the scalp, it can reveal a detection period for alcohol and drugs up to roughly three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch section comprising about 200 hairs (roughly the dimensions of a #2 pencil) located closest to the scalp yields around 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, add-ons, and/or panels exceeding 10, a sample weighing 150mg is advised. It is suggested to use a jeweler’s scale for weighing the sample. If scalp hair is absent, a similar volume of body hair can be used. By head hair, we mean scalp hair exclusively. Body hair includes any other hair types (e.g., facial, axillary, etc.).

Process Overview

The primary stages in the lab handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within a lab's framework. This step involves assuring the sample was properly sealed and delivered, generating a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent from an electronic chain of custody system.

Screening involves an initial cursory examination for drugs of abuse. While Screening is a budget-friendly measure to rule out drug presence in most samples, a positive screening requires confirmation for it to be legally valid. Any samples with a presumptive positive in Screening require a follow-up confirmation.

If a sample is presumptively positive at the Screening stage, additional hair is extracted from the original sample and prepped for Extraction. During this stage, drugs are isolated from hair at significantly lesser concentrations compared to other methods (such as urine or oral fluid), making hair drug testing one of the hardest to conduct.

Confirmation of any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as required. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standard and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug usage for up to 90 days, whereas urine tests have a shorter detection timeframe.
• Hard to deceive: It is notably tough to alter results in a hair drug test, ensuring its accuracy.
• Offers historical data: It provides a usage pattern over time, not just recent activity.

Limitations:

• Inability to detect recent use: Drugs are traceable in hair around 5-7 days post-consumption.
• Expense: Hair drug tests usually incur higher costs than other testing methods.
• Result variations: Factors like hair color and individual hair growth rates can influence the drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", this test assesses the hair strands rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Willards, MD, hair follicle testing is increasingly favored due to its advantages over traditional urine tests. While urine tests focus on recent drug use, hair tests offer a broader history, increasing accuracy and detection reliability.
