What does this test assess?

This panel measures CBD and its metabolites alongside THC compounds, enabling evaluation of the efficacy and composition of consumed hemp preparations.

Clinical indications include:

  • Evaluation of CBD supplementation efficacy
  • Assessment of THC co-exposure from hemp products
  • Quality assurance of CBD product consumption
  • Research on CBD pharmacokinetics and metabolism
Analysed Substances

Measured analytes

Analyte coverage

CBD, CBD-OH (7-hydroxy-CBD), CBD-COOH (7-carboxy-CBD), THC, THC-OH (11-hydroxy-THC), THC-COOH.

Methodology

Analytical technique

All six analytes are quantified simultaneously by LC-MS/MS from a single DBS, providing a complete picture of both CBD and THC metabolism following hemp product consumption.

Frequently Asked Questions

What does the CBD panel measure?

This test quantifies CBD (cannabidiol), THC, and their metabolites from a finger-prick blood spot. Designed to evaluate whether hemp-based products are delivering the cannabinoid levels claimed on the label.

Why test CBD levels in blood?

Oral CBD bioavailability varies hugely depending on formulation, dose, and individual metabolism. Blood testing objectively shows whether a product is producing measurable cannabinoid levels.

How is the sample collected?

Finger-prick DBS card.

How long does it take to get results?

Results are typically delivered within 3 to 5 working days from the time your sample arrives at our laboratory. The analysis is performed by LC-MS/MS.

Will this test detect THC from legal CBD products?

Yes, the test quantifies both CBD and THC metabolites. Some legal CBD products contain trace THC. This panel helps brands and consumers verify that THC levels remain within legal limits.
