Hair Follicle Drug Testing - Zwolle, LA

What it is, How it works

Hair testing is regarded as a robust method for detecting drug and alcohol use. It captures long-term evidence by embedding biomarkers in hair fibers as they grow. When taken from near the scalp, hair offers up to a 3-month detection span for alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is simple.

A 1.5-inch sample of approximately 200 hair strands (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair, perfect for screening and confirmation. For EtG, add-ons, and tests beyond 10 panels, 150mg of the sample is advisable. We suggest using a jeweler's scale for measuring. If scalp hair is unavailable, the same amount of body hair can be used. When indicating head hair, we mean scalp hair only. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning is the preliminary processing of a sample into a lab's system. It includes verifying proper sealing and shipment of the sample, assigning a LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody system.

Screening entails an initial brief assessment for drug usage. It's a cost-effective measure to exclude drug usage in most samples, though a positive screen necessitates confirmation for court admissibility. Samples presumed positive in Screening require further confirmation.

Presumptively positive samples in Screening involve extracting more hair from the original specimen and preparing it for Extraction. In this stage, drugs are extracted from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.

Confirmation of any positive screen occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as needed. The complete laboratory process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests cover a shorter period.
• Difficult to cheat: Cheating a hair drug test is very hard, leading to more accurate results.
• Offers historical data: It provides patterns of drug use over time, not just recent activity.

Limitations:

• Cannot detect recent use: It takes about 5-7 days for drugs to appear in hair.
• Cost: Hair drug tests often cost more than other testing methods.
• Result variations: Factors like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Commonly called "hair follicle tests", the analysis is conducted 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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
