Hair Follicle Drug Testing - Redfield, IA

What it is, How it works

Hair analysis is increasingly viewed as an effective method for identifying substance use involving drugs and alcohol. By capturing indicators within the strands of hair, it allows for a prolonged view of drug consumption. When cut near the scalp, hair can reveal substance use information for up to roughly 90 days for drugs and alcohol. The collection of hair is straightforward, less prone to tampering, and simple to transport.

A sample measuring 1.5 inches, comprising around 200 hairs (approximating the width of a #2 pencil) nearest to the scalp, yields 100mg, which is the optimal amount for testing and verification. For EtG, supplementary tests, and/or panels exceeding 10, a 150mg quantity is advised. It's beneficial to weigh this on a jeweler's scale. Where scalp hair isn't present, a comparable quantity of body hair is acceptable. By head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test follows four principal phases: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample undergoes initial integration into the lab's system. This phase includes checking that the sample was securely sealed and sent correctly, generating a random LAN (Laboratory Accessioning Number), and completing any additional data input not managed by an electronic chain of custody system.

For Screening, an initial check for substance abuse occurs. While Screening offers an economical means to dismiss drug use in most cases, positive findings require confirmation for court validity. All samples indicating presumptive positivity in Screening necessitate additional verification.

Should the Screening phase suggest a positive result, additional hair is extracted from the primary sample for Extraction. In this phase, drugs are separated from the hair at much lower concentrations than other methods (like urine or oral fluid), making hair drug testing a challenging technique to execute.

GC/MS, GC/MS/MS, or LC/MS/MS are methods used for the Confirmation of any preliminary positive results. Before any confirmations are performed, samples marked as presumptive positives undergo a washing process. The entire sequence from Accessioning to Confirmation is conducted following the guidelines of the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use for up to 90 days, in contrast to urine tests which have a shorter time frame.
• Hard to falsify: Manipulating the results of a hair drug test is highly challenging, enhancing their accuracy.
• Reports historical drug use: This method provides insight into a drug usage pattern over time, not just recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug testing typically incurs higher costs compared to other methods.
• Result variability: Aspects such as hair color and individual differences in hair growth can impact drug metabolite levels in the hair.

Note: Although sometimes called "hair follicle tests", the examination targets the hair strand, not the follicle beneath the scalp.
