Hair Follicle Drug Testing - Ercildoun, PA

What it is, How it works

Hair testing is recognized as a highly effective method for identifying substance use, including drugs and alcohol. Hair can reveal long-term substance consumption by encapsulating biomarkers within the strands' fibers as they grow. When hair is collected near the scalp, it can indicate drug and alcohol use over approximately a 3-month period. Hair sampling is straightforward, resistant to tampering, and convenient for transport.

Obtaining a 1.5-inch sample containing roughly 200 hair strands, similar in size to a #2 pencil, yields about 100mg of hair, the optimal amount for both preliminary and confirmatory testing. For tests involving EtG, additional components, and/or more than 10 panels, 150mg is advised. We suggest using a jeweler’s scale for weighing the specimen. In the absence of scalp hair, an equivalent quantity of body hair can be used. "Head hair" pertains solely to scalp hair, while "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for processing drug test samples comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the lab's workflow. This includes confirming correct sample sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any data entry absent from an electronic chain of custody system.

Screening is an initial swift test for detecting drug abuse. While cost-effective in ruling out drug use for most samples, positive results from Screening must be corroborated to be legally valid. Samples deemed presumptively positive in Screening necessitate further confirmation.

With a presumptive Screening positive, additional hair is extracted from the original sample for further examination in the Extraction phase. Here, drugs are isolated from hair at much lower concentrations than with alternative methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.

Confirmation for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, positive samples undergo washing if required. The complete lab process from Accessioning to Confirmation is scrutinized following the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Capable of identifying drug use over a span of up to 90 days, unlike urinary tests which have a shorter duration.
• Challenging to falsify: The stringent nature of hair drug testing minimizes the risk of cheating, ensuring higher accuracy.
• Historical consumption insights: Offers insights into drug use patterns over time beyond just immediate usage.

Limitations:

• No recent use detection: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Generally, hair drug testing incurs higher costs compared to other methods.
• Result variability: Factors such as hair pigmentation and personal hair growth rates can influence metabolite concentrations.

Note: Although commonly referred to as "hair follicle tests," the actual analysis is conducted on the hair strand itself rather than the follicle beneath the scalp.
