Hair Follicle Drug Testing - Goodnoe Hills, WA

What it is, How it works

Hair analysis has emerged as an effective method for identifying alcohol and drug consumption. Hair strands encapsulate long-term biomarker history within their fibers, offering insights into up to about three months of alcohol and drug exposure when collected near the scalp. The collection process is straightforward, the sample is relatively tamper-resistant, and shipment is uncomplicated.

A 1.5-inch piece consisting of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg, providing the optimal quantity for both screening and confirmation purposes. For EtG, supplementary tests, or when exceeding 10 panels, it is advisable to have 150mg of specimen. Utilizing a jeweler's scale for weighing the sample is recommended. In cases where scalp hair isn't available, a similar quantity of body hair can be collected. "Head hair" specifically denotes scalp hair. "Body hair" includes all other hair types (e.g., facial, axillary).

Process Overview

The primary stages in the drug test laboratory process are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where the sample is processed into the lab system. It includes ensuring proper seal and shipment of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent in the electronic chain of custody.

Screening serves as an initial check for substance abuse. Though cost-efficient for ruling out drugs in most samples, any positive results necessitate confirmation to be legally valid. Samples testing presumptive positive require an additional confirmatory procedure.

In the event of a presumptive positive result during Screening, additional hair from the sample is prepared for Extraction. This step involves retrieving drugs from hair at concentrations lower than other methods (like urine or oral fluid), accounting for the complexity of hair drug testing.

Confirmation of a positive Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive are cleaned before confirmation as required. The entire procedure, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation and holds ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair testing identifies drug use up to 90 days prior, unlike urine tests, which have shorter detection spans.
• High resistance to tampering: The integrity of hair drug test results is difficult to compromise.
• Historical consumption data: Can illustrate a timeline of substance use, not simply recent activity.

Limitations:

• No recent use detection: Drugs appear in hair roughly 5-7 days post-use.
• Expense: Hair drug testing costs often surpass those of alternate testing methods.
• Variable results: Drug metabolite concentration may vary due to hair color and individual hair growth differences.

Note: Commonly referred to as "hair follicle tests", this process actually evaluates 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.
