Hair Follicle Drug Testing - Mentasta Lake, AK

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol usage. Hair retains a long-term record of substance use by embedding biomarkers within the fibers of the developing hair strand. When clipped near the scalp, it can offer an approximate 3-month detection period for alcohol and various drugs. Hair is straightforward to gather, relatively challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (about the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is not available, a comparable amount of body hair can be taken. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory evaluation of a drug test outcome entails four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the primary handling of a sample within a laboratory’s framework. This involves confirming that the sample was appropriately sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data input not supplied by an electronic chain of custody system.

Screening is an initial rapid assessment for substance misuse. While it serves as a cost-efficient approach to eliminate substance use in most samples, a positive screen must be verified to be acceptable in a legal context. Any samples showing presumptive positivity in Screening necessitate a secondary confirmation.

If a sample shows presumptive positivity in the Screening phase, additional hair may be taken from the initial sample and readied for Extraction. In this phase, drugs are separated from hair at a significantly lower concentration than other approaches (e.g., urine or oral fluid), making hair drug testing the most complex methodology to conduct.

Any positive screening result undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are cleansed prior to confirmation if required. The entire laboratory protocol from Accessioning to Confirmation is reviewed following both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair tests can identify substance use for up to 90 days, whereas urine tests have a shorter detection period.
• Difficult to manipulate: It is exceedingly hard to manipulate a hair drug test, thus enhancing result accuracy.
• Offers historical insight: It can reveal a drug use pattern over time, not just recent usage.

Limitations:

• Cannot identify recent usage: It takes about 5-7 days for substances to be traceable in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Factors like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Though commonly called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When it comes to accuracy, hair follicle testing outshines urine tests in Mentasta Lake, AK. Hair tests provide a larger detection window and are harder to tamper with, making them a superior choice for those requiring reliable and consistent results.

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.
