Hair Follicle Drug Testing - Churchton, MD

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting alcohol and drug use. Hair records a prolonged timeline of alcohol and drug presence by encasing biomarkers within the hair's growing fibers. When obtained near the scalp, hair offers a detection span of up to about three months for alcohol and drugs. Collecting hair is straightforward, relatively resilient to tampering, and convenient for transportation.

A sample of 1.5 inches of approximately 200 hair strands (about the size of a #2 pencil) near the scalp will yield 100mg, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, or panels surpassing 10, it is advised to collect 150mg of hair. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not available, a corresponding quantity of body hair can be used. When mentioning head hair, it pertains to scalp hair exclusively. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedure for a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into a lab’s system initially. This step includes ensuring the sample was sealed and sent correctly, attributing a random LAN (Laboratory Accessioning Number), and concluding any supplementary data entry absent from an electronic chain of custody system.

Screening involves a preliminary rapid inspection for drugs. Although Screening is economically favorable to exclude drug use in most samples, any positive result necessitates confirmation to be accepted legally. Samples that show a presumptive positive in Screening must undergo a secondary confirmation.

If a sample tests presumptive positive during the Screening phase, further hair is extracted from the initial sample and prepped for Extraction. During Extraction, drugs are isolated from hair in much lower concentrations compared to other methodologies (e.g., urine or oral fluid), underscoring why hair drug testing has the highest complexity among testing methods.

Verification of any positive screening finding is performed with GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive specimens are washed before confirmation as required. All laboratory steps from Accessioning to Confirmation are examined under the CAP (College of American Pathologists) Hair criteria and adhere to the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can find drug usage for up to 90 days, unlike urine tests, which have a briefer detection timeframe.
• Hard to deceive: It is notably challenging to manipulate a hair drug test, ensuring more reliable results.
• Offers a behavioral timeline: It gives evidence of drug use over a timeline, not merely recent activity.

Limitations:

• Cannot indicate recent intake: It requires about 5-7 days for substances to be perceptible in hair.
• Expense: Hair drug tests tend to be costlier compared to other drug testing procedures.
• Differences in outcomes: Elements such as hair pigmentation and personal hair growth differences may alter drug metabolites' concentration in hair.

Note: Though frequently identified as "hair follicle tests", the evaluation focuses on the hair strand and not the hair 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.
