Hair Follicle Drug Testing - Nakaibito, NM

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol usage. Hair offers an extended history of alcohol and other substances by entrapping biomarkers within its strands during growth. When hair samples are collected close to the scalp, they provide an estimated 3-month detection span for alcohol and other drugs. Collecting hair is straightforward, tough to tamper with, and simple to transport.

A 1.5-inch section containing around 200 hair strands (about the same size as a #2 pencil) nearest to the scalp yields 100mg of hair, which is the perfect quantity for both screening and verification. For EtG, add-ons, or tests exceeding 10 panels, a sample of 150mg is advised. We suggest weighing the sample using a precision scale. If scalp hair is not obtainable, a similar amount of body hair can be used. By head hair, we mean scalp hair strictly. By body hair, we refer to hair from other areas (facial, underarm, etc.).

Process Overview

The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample within the laboratory’s system. This includes ensuring the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody system.

Screening involves a preliminary assessment for substances of abuse. While Screening is a cost-effective means to rule out drug usage for most samples, a positive screen must be confirmed to be valid in legal settings. Any sample that tests presumptively positive in Screening requires a secondary confirmation.

Should a sample test presumptively positive during Screening, more hair is retrieved from the initial sample for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is among the most challenging methodologies to carry out.

Confirmation of a positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair label and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal substance use for as long as 90 days, whereas urine tests have a more limited detection period.
• Challenging to deceive: It is highly challenging to manipulate hair drug test results, ensuring greater accuracy.
• Offers historical data: It can showcase a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Incapable of detecting recent use: It takes around 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Result variations: Elements like hair color and personal variations in hair growth can influence drug metabolite concentrations in the hair.

Note: Although often called "hair follicle tests", the analysis is performed 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.

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.
