Hair Follicle Drug Testing - Deshler, NE

What it is, How it works

Hair testing is widely regarded as a crucial method for identifying drug and alcohol consumption. Hair retains a long-term record of drugs and alcohol by embedding biomarkers within the strands as they grow. When hair is sampled near the scalp, it can reveal up to a three-month window of alcohol and drug usage. Hair collection is straightforward, tampering is challenging, and shipping is convenient.

A 1.5-inch section of roughly 200 strands (similar in thickness to a #2 pencil) near the scalp delivers 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advisable. It is suggested to measure the sample using a jeweler's scale. Should there be no scalp hair, an equivalent amount of body hair may be obtained. The term "head hair" specifically denotes scalp hair, while "body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The main stages of laboratory processing in a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial integration into the lab's system. This process verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and ensures any additional data entry not covered by an electronic chain of custody system is completed.

Screening provides a preliminary rapid assessment for drugs of abuse. Though Screening is a cost-effective method to exclude drug usage for most samples, a positive screen needs subsequent confirmation for court admissibility. Any samples indicated as presumptively positive in Screening require further confirmation.

Presumptively positive samples in Screening lead to additional hair being extracted from the original sample for Extraction. During Extraction, drugs are retrieved from hair at much lower concentrations than other methodologies (such as urine or oral fluid); thus, hair drug screening is particularly challenging.

Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to the necessary confirmation. The entire laboratory process, from Accessioning to Confirmation, undergoes review according to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• The detection span is long: up to 90 days of drug use can be identified by hair drug tests, whereas urine tests offer shorter detection periods.
• It is challenging to cheat on a hair drug test, thereby enhancing accuracy.
• Allows for historical data: This test provides a timeline of drug use, not just recent consumption.

Limitations:

• Recent usage is undetectable: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Hair drug tests tend to be pricier compared to other testing methods.
• Result variations exist: Differences like hair color and individual hair growth patterns can influence metabolite concentration in hair.

Note: Commonly labeled as "hair follicle tests," the examination is of the hair strand, not the follicle under 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
