Hair Follicle Drug Testing - Harristown, IL

What it is, How it works

Hair testing is now perceived as a robust method for identifying drug and alcohol consumption. Hair acts as a time capsule for substances like alcohol by embedding biomarkers within the expanding hair strand. When taken from near the scalp, hair can reveal alcohol and drug intake spanning approximately three months. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample length of 1.5 inches, comprising around 200 hair strands (equivalent to the diameter of a #2 pencil) close to the scalp will yield 100mg of hair, which is optimal for screening and confirmation. For EtG, supplemental tests, or panels exceeding 10, a specimen weighing 150mg is advised. Utilizing a jeweler’s scale is suggested for weighing the sample. If scalp hair is not obtainable, a comparable quantity of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair accounts for other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result is primarily divided into four stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial handling of a specimen into a laboratory’s database. This process confirms that the sample was suitably sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and fulfills any extra data entry absent in an electronic chain of custody framework.

Screening is a preliminary test for the presence of drugs. Although Screening is a cost-efficient method to dismiss drug usage in the majority of samples, a positive screen has to be verified to be legally acceptable. Any specimens that return presumptively positive in Screening must undergo secondary confirmation.

If a specimen tests presumptively positive during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. Here, drugs are retrieved from hair at significantly lower concentrations compared to other methodologies (e.g., urine or saliva), making hair drug screening the most intricate method to execute.

Confirmation of any positive screening is undertaken using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are washed before confirmation if necessary. The entire laboratory procedure, from Accessioning through to Confirmation, is scrutinized 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 window: Hair drug tests can identify drug use up to 90 days prior, unlike urine tests, which have a briefer detection period.
• Hard to falsify: Cheating on a hair drug test is extremely challenging, thus enhancing the accuracy of the results.
• Reveals usage history: It offers an overview of drug use over time, rather than just recent consumption.

Limitations:

• Unable to detect recent usage: It generally takes 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variability: Elements like hair color and individual differences in hair growth can influence the levels of drug metabolites in the hair.

Note: Despite the common reference as "hair follicle tests", the analysis focuses on the hair strand and 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.
