Hair Follicle Drug Testing - Clearfield, IA

What it is, How it works

Hair testing is increasingly viewed as an effective means to detect the use of drugs and alcohol. Hair offers a prolonged timeline of alcohol and drug usage by capturing biomarkers within its fibers as it grows. When procured near the scalp, hair can uncover drug and alcohol use for up to an approximate 3-month span. Collecting hair is straightforward, not easily tampered with, and simple to transport.

A specimen of 1.5 inches comprising about 200 hair strands (similar in width to a #2 pencil) closest to the scalp yields 100mg, the optimal sample for checks and verifications. For EtG, add-ons, or tests exceeding 10 panels, 150mg is recommended. It is suggested to measure the specimen using a jeweler’s scale. If head hair isn’t available, a corresponding amount of body hair can be utilized. When mentioning head hair, we solely refer to scalp hair. Body hair denotes all other types, including facial and axillary hair.

Process Overview

The laboratory processing of drug test results encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial entry of a sample into the laboratory system. Tasks include checking that the sample was sealed and delivered correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody.

Screening consists of a preliminary swift check for drug abuse. Although it’s a budget-friendly method to exclude drug usage for most samples, a positive finding in Screening necessitates confirmation for court admission. All presumptively positive samples in this phase require secondary verification.

If a sample shows presumptive positivity in Screening, additional hair is extracted from the initial specimen and readied for Extraction. During Extraction, drugs are retrieved from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of any positive screening results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation if needed. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection timeframe: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests that have a briefer detection window.
• Difficulty in deceit: Hair drug tests are challenging to deceive, enhancing result accuracy.
• Historical data provision: It provides usage patterns over an extended period, not merely recent use.

Limitations:

• Cannot identify recent use: It requires roughly 5-7 days for drugs to surface in hair.
• Expense: Hair drug tests tend to be more costly than other drug testing methods.
• Result variations: Elements like hair color and personal variances in hair growth can influence drug metabolite levels in hair.

Note: While commonly tagged as "hair follicle tests", the examination is conducted on 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.
