Hair Follicle Drug Testing - Claymont, DE

What it is, How it works

Hair examination is now recognized as an effective method for identifying substance and alcohol consumption. Hair offers an extended timeline of drug and alcohol presence by embedding markers within the hair strand as it grows. When obtained from the area nearest to the scalp, hair samples can provide insights into a period of roughly three months for both alcohol and other substances. Collecting hair is straightforward, relatively hard to tamper with, and easy to transport.

A hair sample of 1.5 inches, consisting of approximately 200 hair strands (comparable to the size of a #2 pencil), situated closest to the scalp, will yield 100mg of hair, the preferred quantity for both screening and validation. For EtG, additional tests, and examinations exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure the hair sample using a jeweler’s scale. If scalp hair is not obtainable, a comparable amount of body hair can be gathered. When mentioning head hair, we are specifically referring to scalp hair. Body hair denotes all other hair types (e.g., facial, axillary, etc.).

Process Overview

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

Accessioning involves the preliminary incorporation of a sample into the lab’s system. This step ensures the sample is correctly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry not managed by an electronic chain of custody system.

Screening offers an initial rapid assessment for the presence of illicit drugs. While Screening is a cost-efficient approach to exclude drug use in most samples, a positive result must undergo confirmation for legal admissibility. Samples that yield a positive indication in Screening necessitate secondary confirmation.

Should a sample display a presumptive positive during Screening, additional hair is extracted from the primary sample for preparation in the Extraction stage. During Extraction, drugs are isolated from hair at significantly reduced concentrations compared to alternative approaches (e.g., urine or oral fluid), highlighting why hair drug testing is considered the most challenging methodology.

Any positive indication from Screening is verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are cleansed before confirmation as required. The complete laboratory progression from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can recognize substance use up to 90 days, while urine tests offer a more limited timeframe.
• Challenge to falsify: Cheating in a hair drug test is notably difficult, which enhances result accuracy.
• Historical insight: It offers a timeline of substance use patterns, rather than merely recent consumption.

Limitations:

• Cannot ascertain recent use: Detecting drugs in hair takes about 5-7 days post-use.
• Expense: Typically, hair drug tests incur higher costs than other methods.
• Result variability: Factors including hair color and individual differences in hair growth can influence drug metabolite concentration in the hair.

Note: Although frequently labeled as "hair follicle tests", the analysis 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.
