Hair Follicle Drug Testing - Douds, IA

What it is, How it works

Hair examinations are increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a comprehensive record of alcohol and drugs by capturing biomarkers within the structure of the growing hair strand. When sourced near the scalp, hair offers an approximate 3-month detection span for alcohol and other drugs. Its collection is straightforward, manipulation is relatively difficult, and it is easy to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to measure the specimen is recommended. If scalp hair is unavailable, a comparable quantity of body hair can be collected. Head hair exclusively refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The key stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into a laboratory’s system. This step ensures the sample's seal and shipment integrity, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any data entry lacking in an electronic chain of custody system.

Screening consists of a preliminary evaluation for substance abuse. Although Screening efficiently rules out drug usage for most samples, a positive result requires confirmation for court validity. Samples showing presumptive positives in Screening must undergo further verification.

Should a sample show a presumptive positive in Screening, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted from the hair at much lower concentrations than in other methods (e.g., urine or oral fluid), illustrating why hair drug screenings are among the most challenging methodologies to execute.

Confirmation of any positive Screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all samples with presumptive positives are cleansed as necessary. The comprehensive laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair authorization and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug evaluations recount drug use up to 90 days, in contrast to urine tests which offer a reduced detection span.
• Resistance to falsification: Hair drug tests are challenging to falsify, enhancing result accuracy.
• Generates historical use data: Reveals a drug use pattern over time, not restricted to recent usage.

Limitations:

• Inability to detect recent use: Drugs typically become traceable in hair within 5-7 days post-use.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Variances in results: Variables such as hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Though frequently termed "hair follicle tests", the analysis targets 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.
