Hair Follicle Drug Testing - East Shasta, CA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug intake by capturing biomarkers within the hair's structure as it grows. When samples are taken near the scalp, they can offer a detection timeframe of up to around 90 days for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to ship.

A 1.5-inch section of roughly 200 hair strands (similar to the diameter of a #2 pencil) close to the scalp provides 100mg of hair, which is the optimal amount for both screening and verification. For tests involving EtG, additional assessments, or panels exceeding 10, a specimen weight of 150mg is advised. Utilizing a jeweler’s scale is recommended to weigh the sample. If scalp hair is insufficient, a corresponding quantity of body hair may be used. When mentioning head hair, we mean scalp hair solely. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test samples primarily involves four stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing within the laboratory’s infrastructure. This process includes checking that the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

The Screening phase performs an initial rapid analysis for controlled substances. While Screening is a budget-friendly approach to eliminate drug use in most samples, a positive result must be verified to be legally valid. Samples that test positive initially require an independent confirmation.

Should a sample yield a positive result during Screening, additional hair is extracted from the original sample and prepped for Extraction. This step involves the isolation of drugs from hair at significantly lower concentrations than in other testing methods (e.g., urine or oral fluid), highlighting why hair testing is the most challenging technique to administer.

Confirmation of any positive Screening result is achieved through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples yielding presumptive positives undergo washing before Confirmation if necessary. The end-to-end laboratory procedure, from Accessioning to Confirmation, is evaluated according to both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for as long as 90 days, in contrast to urine tests, which have shorter detection periods.
• Challenging to manipulate: Due to the difficulty of falsifying a hair drug test, the results are more reliable.
• Offers historical insight: It provides a timeline of drug usage over an extended period, not merely recent usage.

Limitations:

• Incapable of detecting recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Generally, hair drug testing costs more than other methods of drug testing.
• Result variability: Elements such as hair color and individual differences in hair growth can influence the levels of drug metabolites in hair.

Note: Although often termed "hair follicle tests," the analysis actually focuses on the hair strand, not the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
