Hair Follicle Drug Testing - Watson, MN

What it is, How it works

Hair analysis is now acknowledged as an effective means for detecting drug and alcohol consumption. The hair serves as a historical record of substances like alcohol and other drugs by embedding biomarkers within its strands as the hair grows. Positioned near the scalp, hair can yield a detection period extending to roughly three months for substances. It's uncomplicated to gather, moderately tough to tamper with, and straightforward to transport.

A hair segment measuring 1.5 inches containing around 200 strands (comparable in size to a #2 pencil) closest to the scalp supplies 100mg of hair, which is an optimal amount for both screening and validation. For EtG, additional tests, or those exceeding 10 panels, a 150mg specimen is suggested. It is advised to weigh the sample with a jeweler’s scale. Should scalp hair not be present, a similar quantity of body hair might be used. Head hair specifically denotes scalp hair. Body hair encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial incorporation of a sample into the laboratory's system. This step verifies that the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any further data input absent in an electronic chain of custody system.

Screening signifies an initial expeditious assessment for drugs of concern. While Screening economically discounts drug use in most samples, any positive outcomes require Confirmation to be valid in legal contexts. Any screening samples that are presumptively positive necessitate additional validation.

During the Screening stage, if a sample tests presumptively positive, additional hair is taken from the initial sample and readied for Extraction. At this juncture, drugs are separated from the hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging.

Any positive findings from Screening undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample is washed before Confirmation as necessary. Every aspect of the laboratory protocol from Accessioning to Confirmation undergoes scrutiny under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can ascertain drug use for up to 90 days, unlike urine tests, which have a more limited detection span.
• Difficult to deceive: Tampering with a hair drug test is quite challenging, thereby enhancing the reliability of results.
• Offers historical insights: It reveals a pattern of drug usage over time, rather than just immediate consumption.

Limitations:

• Incipient use not detected: It requires roughly 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing methods.
• Result variability: Elements like hair color and personal hair growth differences can impact the metabolite concentration in hair.

Note: Although frequently termed "hair follicle tests," the procedure involves examining 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.
