Hair Follicle Drug Testing - Cape Saint Claire, MD

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug usage by capturing biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can offer up to a three-month detection period for alcohol and other drugs. Hair collection is straightforward, somewhat challenging to tamper with, and simple to transport.

A 1.5-inch section comprising approximately 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. It's recommended to weigh the sample on a jeweler’s scale. If scalp hair isn't available, a corresponding amount of body hair can be collected. When referencing head hair, it indicates only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key stages in the laboratory processing of a drug test outcome comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a specimen into a laboratory's infrastructure. This step includes verifying proper sample sealing and shipment, assigning a randomized LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening is an economical method to rule out drug usage in most samples, a positive screen must be confirmed for court admissibility. Any samples preliminarily positive in Screening necessitate a secondary confirmation.

Should a sample test presumptively positive in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this stage, drugs are isolated from hair at much lower concentrations than other methodologies (e.g., urine or saliva), which is why hair drug testing is the most complex methodology to execute.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo necessary washing before confirmation. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests, which have a shorter detection timeframe.
• Challenges in cheating: It is extremely difficult to cheat a hair drug test, enhancing the accuracy of results.
• Offers historical usage data: It can reveal a pattern of drug use over time, beyond just recent consumption.

Limitations:

• Inability to detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally cost more than alternative drug testing methods.
• Result variances: Factors such as hair color and individual hair growth variations can influence the drug metabolite concentration in hair.

Note: Although commonly labeled as "hair follicle tests", the analysis involves the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Cape Saint Claire, MD presents significant advantages over traditional urine tests.

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.
