Hair Follicle Drug Testing - Terril, IA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol usage. Hair strands capture biomarkers, preserving a long-term record of alcohol and drug consumption. When hair samples are taken close to the scalp, they can reveal a substance use history of up to about 90 days. Collection is straightforward, tampering is challenging, and shipping is convenient.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (comparable to the thickness of a #2 pencil), and closest to the scalp provides an optimal 100mg for assessment and confirmation. For EtG, additional tests, or panels over 10, a specimen of 150mg is advised. It's suggested to weigh the sample with a jeweler’s scale. In the absence of scalp hair, a corresponding quantity of body hair can be gathered. References to head hair specifically concern scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary incorporation of a sample into a lab's system, which includes checking that the sample is securely sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry absent in an electronic chain of custody system.

Screening offers an initial evaluation for drug misuse. While Screening provides an economical means to eliminate drug usage in most samples, any positive findings necessitate confirmation to be legally acceptable. Samples yielding presumptive positive results in Screening require further confirmation.

In cases where initial Screening results are presumptive positives, additional hair is extracted from the initial sample for the Extraction phase. Drugs are removed from hair at significantly lower concentrations than in other techniques (such as urine or oral fluid), rendering hair drug screening a complex process.

GC/MS, GC/MS/MS, or LC/MS/MS methods are used for confirming any positive Screening results. Preceding Confirmation, positive samples are washed as needed. From Accessioning to Confirmation, the entire lab procedure is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug usage over 90 days, unlike urine tests with shorter windows.
• Hard to manipulate: Cheating a hair drug test is incredibly challenging, ensuring more precise results.
• Provides usage history: It yields a broader picture of drug consumption patterns over time, not merely recent usage.

Limitations:

• Lack of recent use detection: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug testing typically incurs higher costs compared to other methods.
• Result variations: Hair color and individual hair growth differences can influence drug metabolite concentrations.

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