Hair Follicle Drug Testing - Whittemore, IA

What it is, How it works

Utilizing hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and other substances by embedding biomarkers within the strands of emerging hair. When obtained near the scalp, hair can offer up to about a 3-month detection period for alcohol and various drugs. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to transport.

Securing a 1.5-inch sample consisting of roughly 200 hairs (comparable to a #2 pencil's diameter) nearest to the scalp will yield 100mg of hair, which is the optimal sample for evaluation and corroboration. For EtG, supplementary tests, and/or panels exceeding 10, 150mg of the sample is advised. It is suggested to measure the specimen's weight with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be taken. When discussing head hair, it pertains only to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The four key procedures in processing a laboratory drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the early processing of a specimen into the laboratory's system. This step ensures the sample was properly sealed and sent, appoints a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening involves a primary rapid assessment for drugs of abuse. While it is a cost-efficient approach to eliminate drug use in most samples, a positive screen requires confirmation for submission in court. Any samples appearing positive in Screening necessitate an additional confirmation.

Should a sample appear positive during the Screening phase, further hair is taken from the initial specimen and prepared for Extraction. In this phase, drugs are extracted from hair at considerably lower concentrations compared to other methodologies (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to conduct.

Verification of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as needed. The comprehensive laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair categorization and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a shorter detection span.
• Reduced chance of tampering: It is highly challenging to tamper with a hair drug test, increasing the accuracy of results.
• Provides historical insight: It can reveal a drug use pattern over time, not merely recent consumption.

Limitations:

• Unable to detect recent consumption: It generally takes about 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests tend to be costlier compared to other drug testing techniques.
• Result variations: Factors such as hair pigmentation and individual differences in hair development can impact the concentration of drug metabolites in the hair.

Note: While typically termed "hair follicle tests", the examination focuses 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.
