Hair Follicle Drug Testing - Oak Hall, VA

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by encapsulating biomarkers within the strands of the growing hair. When sourced near the scalp, hair can offer a detection window of up to roughly three months for both alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A hair sample measuring 1.5 inches with around 200 strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For tests like EtG, add-ons, or screens exceeding 10 panels, a quantity of 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair not be available, an equivalent quantity of body hair may be utilized. For head hair, this specifically denotes scalp hair. Body hair encompasses all other varieties (such as facial or axillary hair).

Process Overview

The laboratory procedures involved in determining a drug test result encompass four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing within a laboratory's system. This involves checking that the sample was adequately sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and executing any supplemental data entry absent from an electronic chain of custody system.

Screening serves as a preliminary rapid assessment for drugs of concern. Though Screening is cost-effective for excluding drug use in most samples, a positive finding requires validation to be accepted in legal proceedings. Samples registering a preliminary positive in Screening necessitate further confirmation.

For any sample that tests presumptively positive during the Screening phase, additional hair is extracted from the original sample to prepare for Extraction. In this process, substances are extracted from hair at a significantly lower concentration than other methods (such as urine or oral fluid), rendering hair drug analysis the most challenging to conduct.

Confirmation for any positive Screening result is performed using methods like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as required. The entire lab process ranging from Accessioning to Confirmation is thoroughly reviewed under both the CAP (College of American Pathologists) Hair designation and is accredited to the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Expanded detection period: Hair drug testing can identify drug usage for as long as 90 days, as opposed to urine testing which has a shorter detection span.
• Challenging to falsify: Falsifying a hair drug test is notably difficult, increasing result accuracy.
• Offers historical insights: It can illustrate a timeline of drug consumption over extended periods, not just recent use.

Limitations:

• Incapable of detecting recent usage: It takes about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests generally incur higher costs than other drug testing methods.
• Result variations: Factors like hair color and individual differences in hair growth can influence the presence of drug metabolites in hair.

Note: Although sometimes termed "hair follicle tests", the analysis is carried out on the hair strand and not on the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Oak Hall, VA, hair follicle testing consistently proves superior to urine testing for detecting substance use. While urine tests detect recent drug use, hair analysis provides an extended detection period of 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.
