Hair Follicle Drug Testing - Ledyard, IA

What it is, How it works

Hair examination is widely acknowledged as an effective method for identifying drug and alcohol consumption. Hair encapsulates a long-term record of alcohol and other substances by embedding biomarkers within the strands as they grow. When collected near the scalp, hair can offer a detection period of up to roughly 3 months for alcohol and drugs. The collection of hair is straightforward, moderately resistant to tampering, and convenient for transport.

A sample measuring 1.5 inches with roughly 200 hair strands (approximately the size of a #2 pencil) near the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen weighing 150mg is recommended. It's advised to measure the specimen using a jeweler’s scale. In case scalp hair is not available, an equivalent quantity of body hair can be used. In this context, head hair specifically denotes scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is concerned with the initial integration of a sample into the laboratory’s system. This step involves verifying the integrity and proper shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry tasks not covered by an electronic chain of custody system.

Screening entails a preliminary rapid examination for drug abuse. While Screening is a cost-efficient method for excluding drug use in most samples, a positive screen necessitates confirmation for legal admissibility. Samples that are presumptively positive during Screening require a secondary confirmation.

If the Screening phase yields a presumptive positive result, additional hair is extracted from the original specimen for the Extraction phase. This stage involves extracting drugs from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

The Confirmation phase for positive screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation if necessary. The complete procedure from Accessioning to Confirmation is scrutinized 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 use up to 90 days, whereas urine tests have a shorter timeframe.
• Low probability of manipulation: It's quite challenging to circumvent a hair drug test, contributing to more reliable outcomes.
• Historical usage insight: It offers a trend of drug use over time, not solely recent consumption.

Limitations:

• Incapacity to detect recent use: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair drug tests usually cost more than alternative drug testing techniques.
• Variable outcomes: Elements like hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Despite commonly being termed "hair follicle tests", the assay actually examines the hair strand and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Ledyard, IA, hair follicle testing outperforms traditional urine tests. The capability of hair testing to detect drug use over months versus days signifies superior detection accuracy.
