Hair Follicle Drug Testing - Solana Beach, CA

What it is, How it works

The utilization of hair testing has emerged as an effective methodology for identifying drug and alcohol consumption. Hair retains a historical record of substances by encapsulating biomarkers within its fibers. When retrieved from a position near the scalp, hair can deliver a detection window extending up to 3 months for drugs and alcohol. Its collection is straightforward, moderately resistant to tampering, and easy to transport.

A sample measuring 1.5 inches comprised of around 200 hair strands (equivalent to the thickness of a #2 pencil) near the scalp ensures a sample weight of 100mg, optimum for both screening and confirmation. For EtG, supplementary tests, and/or panels exceeding 10, a specimen weighing 150mg is advised. We suggest using a jeweler’s scale for weighing. Should scalp hair be inaccessible, an equivalent quantity of body hair is accepted. "Head hair" denotes scalp hair exclusively, whereas "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing drug test results comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample’s preliminary processing into a laboratory system. This process entails ensuring proper sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and filling in any additional data entry absent from an electronic chain of custody system.

Screening offers an initial swift evaluation for drugs of abuse. While Screening provides an economical approach to identifying potential drug use across most samples, a positive result requires confirmation to be valid in legal situations. Any Screening stage presumptive positives necessitate further confirmation.

In case of a presumptive positive during Screening, additional hair from the initial sample is prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology.

Confirmation follows via GC/MS, GC/MS/MS or LC/MS/MS for any positive screening outcomes. Presumptive positive samples are cleaned prior to confirmation as needed. Every stage from Accessioning to Confirmation is scrutinized according to both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests which have a shorter timeline.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, which ensures more reliable results.
• Reveals patterns: It shows a record of drug use over time, not just immediate use.

Limitations:

• Inability to detect recent consumption: Drugs take approximately 5-7 days to be identifiable in hair.
• Expense: Hair drug testing typically incurs higher costs than other methods.
• Result variability: Factors like hair color and personal differences in hair growth can influence metabolite concentrations.

Note: Despite being often coined "hair follicle tests", the actual analysis is conducted on the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outshine urine tests in Solana Beach, CA? Hair tests offer superior detection accuracy and reliability.

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.
