Hair Follicle Drug Testing - Samish, WA

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol usage. Hair records a prolonged history of substance use by encapsulating biomarkers within the fibers of the emerging hair strand. When hair is gathered near the scalp, it can offer about a 3-month detection period for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch strand sample containing roughly 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp will yield 100mg of hair, an ideal amount for both screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the specimen. In the case where scalp hair is not available, a comparable volume of body hair can be utilized. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

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

Accessioning comprises the initial phase of processing a sample within a laboratory’s system. This entails verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening includes a preliminary rapid assessment for drugs of abuse. Though Screening is an economical approach to exclude drug usage in the majority of samples, a positive screen must be verified for court admissibility. Any samples that test presumptively positive in Screening require a subsequent confirmation.

If Screening indicates that a sample is presumptively positive, additional hair is extracted from the original specimen and prepared for Extraction. During this phase, drugs are extracted from hair at much lower concentrations than in other methodologies (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to execute.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned prior to confirmation as necessary. From Accessioning to Confirmation, the entire laboratory process is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests have a shorter detection period.
• Hard to deceive: Hair drug tests are very challenging to falsify, resulting in more accurate findings.
• Delivers chronological data: It reflects a pattern of drug use over time, not solely recent use.

Limitations:

• Inability to detect recent use: It generally takes 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically more costly than other drug testing methods.
• Result variations: Factors like hair color and personal differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: Although often called "hair follicle tests", the analysis involves the hair strand, rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair follicle testing over urine testing in Samish, WA? Hair tests offer superior detection accuracy and are more reliable. While urine tests are standard, hair testing is preferred due to its inability to be easily manipulated.

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.
