KIDney Injury in Times of COVID-19 (KIDCOV) Study

This observational study, called KIDCOV, is looking at how COVID-19 (SARS-CoV Infection, Corona Virus Infection) might affect your kidneys, even if you had a mild case. Researchers want to understand if people who had COVID-19 develop new or worsening kidney injury (Acute Kidney Injury, Kidney Injury) over time. They will compare people who tested positive for COVID-19 with those who tested negative. You can join if you are 18 or older and had a PCR-based COVID-19 test in the last four weeks. The study will measure a 'KIT Score' from your urine over one year to see if kidney injury occurs. The goal is to better understand and prevent kidney damage after COVID-19.

Study design
This is an observational study involving 2000 participants. It follows groups of people who tested positive and negative for COVID-19 over 12 months.
What's involved
You will complete questionnaires and return urine samples using mailed collection kits at 2, 6, and 12 months after your PCR test date. You won't need to leave your home to participate.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 12 months after their PCR test date.

  • Continuous, Quantitative KIT Score1 year

    The 12-month continuous, quantitative Kidney Injury Test (KIT) score, measured on a scale of 0-100, where a higher urine-based KIT score correlates to worse kidney injury.
