Hair Follicle Drug Testing - Upper Marlboro, MD

What it is, How it works

Hair analysis is now regarded as an effective means to identify drug and alcohol consumption. Hair retains a prolonged record of alcohol and drugs by capturing biomarkers within its growing strands. When hair is gathered close to the roots, it can detect alcohol and drugs for up to three months. This method is easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch lock consisting of about 200 hairs (roughly the thickness of a #2 pencil) from near the scalp provides 100mg, the optimal amount for both screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, it is advised to collect a specimen weighing 150mg. The specimen should be weighed using a jeweler’s scale. If head hair is unavailable, an equivalent quantity of body hair may be used. Specifically, head hair refers exclusively to scalp hair, while body hair encompasses all other types such as facial or axillary hair.

Process Overview

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

Accessioning includes the sample's preliminary entry into a lab's system, ensuring its seal and proper shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody.

Screening involves an initial rapid drug-use check. Although Screening is economical for eliminating drug use in most samples, any positive finding must be verified to be accepted in court. Presumptive positives in the Screening stage require further confirmation.

If Screening suggests a positive result, more hair is extracted from the sample for the Extraction process. During Extraction, drugs are isolated from hair at a much lower concentration than other methods (e.g., urine or saliva), highlighting the complexity of hair drug testing.

To verify any positive screening outcomes, confirmation is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive results undergo washing before confirmation as needed. The complete lab process from Accessioning to Confirmation is verified under the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage over up to 90 days, unlike urine tests which have shorter detection periods.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, leading to more reliable results.
• Reflects usage patterns: Provides insights into drug use trends over time, rather than just recent activity.

Limitations:

• Incapable of recent detection: Detection of drugs in hair takes around 5-7 days.
• Expense: Hair drug tests tend to be costlier than other testing methods.
• Result variability: Attributes like hair color and personal hair growth differences may impact drug metabolite levels in hair.

Note: Though often called "hair follicle tests", the analysis focuses on the hair strand, not the hair root under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers significant advantages over traditional urine tests in Upper Marlboro, MD. Superiority in detection is evident through a longer detection window, capturing substance use history up to 90 days.

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.
