Hair Follicle Drug Testing - Mason City, NE

What it is, How it works

Hair testing has become a recognized means for detecting drug and alcohol usage. Hair holds an extensive history of alcohol and drugs by capturing biomarkers within the fibers of the developing hair strand. Collected near the scalp, hair offers roughly a 3-month detection window for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and easily shippable.

A 1.5-inch sample of roughly 200 hair strands (around the size of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal sample for screening and verification. For EtG, add-ons, and/or panels beyond 10, 150mg of the specimen is advisable. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair is absent, a similar quantity of body hair can be gathered. Head hair refers specifically to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

There are four major steps in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the sample’s initial processing into the lab's system. It involves verifying proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and performing any further data entry that is not covered by an electronic chain of custody system.

Screening provides an initial swift evaluation for drugs of abuse. Though Screening is a cost-effective method for eliminating drug use in most samples, a positive screening necessitates confirmation for court admissibility. Samples presumed positive in Screening demand a secondary confirmation.

If a sample is presumed positive at the Screening phase, more hair is extracted from the initial sample and prepped for Extraction. Here, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), explaining why hair drug screening presents the greatest methodological challenge.

Any positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are washed prior to confirmation as required. The comprehensive lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Resistant to tampering: Hair drug tests are hard to manipulate, ensuring greater accuracy.
• Offers use history: It demonstrates a trend of drug use over time, beyond immediate use.

Limitations:

• Not suitable for immediate detection: It usually takes 5-7 days for drugs to show in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Factors like hair color and personal variations in hair growth can influence the drug metabolite levels in the hair.

Note: These tests are often termed "hair follicle tests", yet they analyze the hair strand rather than 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.
