About PERSIAN Cohort
The Prospective Epidemiological Research Studies in IrAN (PERSIAN) is a nationwide cohort study launched in the year 2014 in an attempt to encourage research in the fields of medicine, epidemiology, health, and nutrition. PERSIAN has empowered medical schools around the country with the necessary resources to take part in the study, in order to identify the risk factors related to the most prevalent chronic diseases in Iran, with the ultimate goal to reform the health system and enhance the health of Iranians, while contributing to the world’s medical knowledge.

The PERSIAN Cohort Biobank
Developing a biobank— a type of repository storing biological samples—has become an important part of clinical research in the past few decades. If stored under the appropriate conditions, a variety of biological specimens can be kept for many years, and be used for research in medical, epidemiological, and genetic studies, ideally to identify new biomarker, onco-markers or genes causing disease in a large section of the population.
A variety of samples are stored in the PERSIAN Cohort biobank. Samples are taken at enrollment. If one of the study’s main outcomes of interest is noted in the follow up phase (cancer or other disease development), additional blood samples are taken and stored. A fraction of aliquoted samples are stored in local biobanks at the cohort centers, and a fraction is stored centrally in the PERSIAN Cohort Central Biobank. The PRESIAN Cohort Laboratory Information Management System is designed and used for easy tracking and access to samples.
