Hair Follicle Drug Testing - Morgan Hill, CA

What it is, How it works

Hair testing is recognized as an efficient means of identifying drug and alcohol consumption. Hair serves as a lengthy record of alcohol and drug intake by capturing biomarkers within its strands as they grow. When extracted near the scalp, hair can reveal up to about a 3-month range of detection for alcohol and drugs. Collection of hair is straightforward, hard to tamper with, and convenient to transport.

A sample of 1.5 inches, comprising roughly 200 hair strands (comparable to the thickness of a #2 pencil) taken nearest to the scalp, yields 100mg, which is ideal for both screening and confirmation procedures. For EtG, additional panels beyond the standard 10-panel tests, 150mg of hair is advised. It's suggested to weigh the specimen on a jeweler’s scale. Should scalp hair be unavailable, a comparable amount of body hair may be used. Head hair exclusively refers to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The processing of a drug test result in the lab involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of integrating a specimen into a laboratory's workflow. This process involves verifying the integrity and proper shipment of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and finalizing any remaining data entry not captured by an electronic chain of custody mechanism.

Screening entails an initial rapid assessment for drug traces. While Screening offers a cost-efficient method to rule out substance use for most samples, a positive initial result must be validated to hold up legally. Samples that test presumptively positive during Screening require a follow-up confirmation.

Presumptively positive samples lead to more of the original hair being extracted for further testing. During Extraction, drugs are pulled from hair at significantly lower concentrations than other procedures (such as urine or oral fluid), making hair drug screening one of the most challenging methods to administer.

Confirmation of any positive Screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumptively positive are cleansed prior to confirmation if necessary. From Accessioning through Confirmation, the entire lab process adheres to standards established by CAP (College of American Pathologists) for Hair and is accredited under ISO / IEC 17025 guidelines.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can track drug usage for up to 90 days, unlike urine tests with shorter detection spans.
• Hard to manipulate: Hair drug tests are notably hard to tamper with, ensuring reliable results.
• Offers historical insight: The tests can document drug use patterns over time, rather than only recent activities.

Limitations:

• Incapable of identifying recent use: Drugs require about 5-7 days post-use to become traceable in hair.
• Expense: Hair drug testing is often pricier compared to other methods.
• Result variations: Drug metabolite concentrations in hair can be affected by factors like hair color and individual growth rates.

Note: Although commonly called "hair follicle tests", the analysis targets the hair strand rather than the scalp's hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Morgan Hill, CA
Hair follicle testing provides a more comprehensive detection method compared to traditional urine tests. Its superior accuracy offers better insights into substance use with less risk of false negativity.

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.
