Hair Follicle Drug Testing - Greeley Center, NE

What it is, How it works

Hair assays have gained reputation as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands of continuously growing hair, it offers a prolonged overview of alcohol and drug use. If gathered near the scalp, hair can reveal a roughly 3-month detection period for alcohol and drugs. Its collection is straightforward, difficult to tamper with, and convenient for shipping.

A 1.5-inch section consisting of around 200 hair strands (comparable in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is the perfect sample size for both screening and confirmation processes. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advised. We suggest using a jeweler’s scale for an accurate specimen weight. If scalp hair cannot be collected, an equivalent amount of body hair may be used. "Head hair" denotes scalp hair alone. "Body hair" refers to all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning pertains to the initial integration of a sample into a laboratory’s system. It involves confirming that the sample was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional entry needed that isn’t covered by an electronic chain of custody system.

Screening serves as an initial broad assessment for drug abuse. Though Screening is a cost-effective means to eliminate drug usage in many samples, a positive result must be confirmed to be valid in legal contexts. All samples with a presumptive positive result in Screening necessitate subsequent confirmation.

If Screening yields a presumptive positive, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), explaining why hair drug screening presents the greatest challenge.

Confirmation of positive screenings is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. From Accessioning to Confirmation, the entire process is evaluated under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests with shorter windows.
• Hard to manipulate: Cheating a hair drug test is highly difficult, enhancing result accuracy.
• Tracks historical patterns: It can reveal usage patterns over time, rather than just recent instances.

Limitations:

• Detects less recent use: Drugs take around 5-7 days to appear in hair.
• Expense: Hair drug assays typically cost more than other testing methods.
• Results vary: Elements like hair color and personal differences in growth can impact metabolite concentrations in hair.

Note: Although commonly known as "hair follicle tests", the procedure assesses the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Greeley Center, NE, hair follicle testing presents clear advantages over traditional urine tests. A primary benefit is the superior detection accuracy.

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.
