Hair Follicle Drug Testing - Snoqualmie Valley, WA

What it is, How it works

Hair examinations have become recognized as an effective method for identifying alcohol and drug consumption. Hair captures a prolonged timeline of drug and alcohol use by embedding biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, it can reflect a detection period of up to about 90 days for drugs and alcohol. Hair is straightforward to gather, relatively challenging to alter, and convenient to send.

A sample measuring 1.5 inches, consisting of roughly 200 strands of hair close to the scalp, yields 100mg of hair, which is the optimal amount for preliminary assessments and confirmations. For tests exceeding 10 panels, add-ons, or EtG, a 150mg sample is advised. We suggest utilizing a jeweler’s scale to measure the sample. In cases where scalp hair cannot be obtained, an equivalent quantity of body hair may be used. References to head hair pertain solely to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The lab processing of drug test results involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is integrated into the lab’s system. This step involves confirming that the sample was properly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any absent data entry not captured by an electronic chain of custody system.

Screening involves a preliminary examination for drug detection. Though it is economical to eliminate drug use for the majority of samples, a positive result in Screening requires Confirmation to be legally acceptable. Samples that show presumptive positivity during Screening necessitate further Confirmation.

Should a sample seem positive in the Screening, additional hair is taken from the original sample for Extraction. At this point, drugs are extracted from hair at notably lower concentrations compared to methodologies like oral fluid or urine, underscoring the complexity of hair drug testing.

Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples are cleansed prior to Confirmation as necessary. The process from Accessioning through Confirmation is regulated under the CAP (College of American Pathologists) Hair program and follows the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests extend detection to approximately 90 days, offering a longer window than urine tests.
• Difficult to manipulate: The hair drug test is not easily deceived, yielding more reliable results.
• Delivers historical insights: It reveals drug usage patterns over time, instead of merely recent consumption.

Limitations:

• Cannot identify recent usage: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests tend to cost more than other drug testing techniques.
• Result variability: Factors like hair color and growth differences can influence drug metabolite concentrations.

Note: The term "hair follicle tests" is commonly used; however, the analysis is conducted on the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Comparing hair follicle testing to traditional urine tests shows why it's often preferred in Snoqualmie Valley, WA. Hair tests offer superior detection accuracy and reliability, revealing drug use long after it occurs.

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.
