Hair Follicle Drug Testing - Secor, IL

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol usage. The hair retains a prolonged history of substance intake by encapsulating biomarkers within the hairs' growing strands. When clipped near the scalp, it can offer a detection timeframe of approximately three months for alcohol and other substances. Hair is easy to collect, relatively hard to tamper with, and straightforward to transport.

A 1.5-inch segment comprising approximately 200 hair strands (resembling a #2 pencil's diameter) from as close to the scalp as possible will yield 100mg of hair, which is the preferable quantity for screening and verification. For EtG, supplements, and/or analyses exceeding 10 panels, 150mg of the sample is advised. It's preferred to measure the sample's weight using a jeweler's scale. If scalp hair is absent, a proportionate amount of body hair might be collected. When mentioning head hair, we are specifically discussing scalp hair. Body hair pertains to other types such as facial, axillary, etc.

Process Overview

The primary stages in laboratory processing for a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a lab's system. This involves affirming the proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and concluding any extra data entry not covered by an electronic chain of custody system.

Screening consists of an initial rapid evaluation for substances of misuse. While Screening is an economical method to exclude drug consumption in the majority of samples, a positive result necessitates confirmation to be court-admissible. Any samples that are presumably positive in Screening require further confirmation.

Should a sample test presumptively positive at the Screening phase, additional hair is taken from the original sample for Extraction. In this stage, substances are extracted from hair at a notably lower concentration than in other analyses (ex. urine or oral fluid), which is why hair drug screening is among the most challenging methodologies to execute.

Verification of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed prior to confirmation as necessary. The entire lab process from Accessioning to Confirmation is reviewed by both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection timeline.
• Difficulty to falsify: It's exceedingly challenging to deceive a hair drug test, enhancing result precision.
• Provides historical context: It offers a consumption pattern over time, rather than just recent usage.

Limitations:

• Inability to detect recent intake: It takes about 5-7 days for substances to be traceable in hair.
• Expense: Hair drug tests are typically pricier than other drug evaluating techniques.
• Result variability: Aspects such as hair color and personal differences in hair growth can influence the concentration of drug metabolites within hair.

Note: As often noted as "hair follicle tests," the examination actually assesses the hair strand, not the hair 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.

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.
