Pollendaten für klinische oder wiss. Studien

Clinical Trial Information

Are you a clinical trial investigator site, a CRO or a pharmaceutical company thinking about using www.polleninfo.org forecasts for pollen level reporting in a clinical trial?

Clinical trials need actual measurements of pollen counts in a given area, proving the levels of pollen and detailed breakdowns of pollen to which patients were actually exposed.

Pollen forecasts, as displayed on www.polleninfo.org, are not suitable as a substitute for volumetric pollen counts during clinical trials.

Pollen forecasts provide a valuable report of highly likely upcoming pollen levels for many purposes. Pollen forecasts are closely tied to forecasted weather. If forecasted weather does not prove accurate, the forecasted pollen levels may not apply, and will likely be divergent from actual pollen counts. Allowing this possibility, during highly precise clinical trials, is generally not acceptable.
Clinical trials, sponsored by pharmaceutical companies function on an entirely different set of standards than our consumer pollen forecasts. Most clinical trial protocols require pollen data that is as detailed and precise as possible. Actual pollen counts are used in most clinical trials to give a very detailed, scientific description of all pollinating plant taxa and their levels in parts per cubic metre of air. These very detailed counts rely on many different aspects: properly functioning equipment, qualified pollen counters, exact calculations giving the pollen grains per cubic metre of air, the placement of air sampling equipment, and many other variables. Actual pollen counts for clinical trials are held to rigid European standards. They are taken in a very uniform fashion, guaranteeing the most accurate pollen count data possible. This is imperative to properly correlate pollen counts with patient symptom data.

There may be few instances in which seasonal and daily pollen forecasts are used in clinical trials. They are helpful in determining areas of the country in which to place investigator sites during a given season. It may also be possible that the protocol calls for only qualitative, as opposed to quantitative, pollen levels. We can discuss your needs with you to help determine which type of data is best, making sure you are covered before your study even starts.

We can provide a range of reliable pollen count or forecast services in Europe to meet the needs of most clinical trials, including:

  • Calibrated sampling equipment
  • Documented sampling site setup
  • Sampling site training
  • Microscopic pollen analysis by highly qualified personnel
  • Identification of pollen and spores down to 60 or more different taxa
  • Database of volumetric data (European Aeroallergen Network, EAN)
  • Interpretation of data
  • Pollen/spore sampling spatial coverage appropriate for your patient population


Our researchgroup, the people behind the www.polleninfo.org forecasts, can help you obtain the European volumetric pollen counts you need for your study. We’ve been providing this type of reliable service to clinical trials for many years, and we can assist your trial, too.
