An observational study in SARS-CoV Infection, Covid19 and Corona Virus Infection, sponsored by University of California, San Francisco. Enrolling by invitation at 3 sites in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-11.

There is an unmet need to evaluate the impact of sub-clinical/mild COVID19 disease in the outpatient setting on prevalent and incident renal injury, as this data is currently unavailable. To capture the diversity of race/ethnic risk and COVID19 related municipal shelter-in-place guidance, the investigators will enroll COVID19-negative and COVID19-positive samples balanced by race/ethnicity from 3 different states, California, Michigan, and Illinois. Study endpoints will be assayed from urine samples mailed to the study team at 2, 6, and 12 months after their date of PCR test, with no requirement for these individuals to leave their homes to participate.
KIDCOV is a longitudinal cohort study that will prospectively follow cohorts of COVID19-negative and COVID19-positive adults for episodes of kidney injury over a 12-months period. Study candidates will be identified via site-specific electronic medical records (EMR) at seven academic medical centers in the U.S. within 4 weeks of a PCR-based test for SARS-Cov2. Screen-positive individuals will be contacted by email or text and invited to complete an online consent form documenting their willingness to participate. Participation will involve completion of questionnaires and return of urine samples in mailed collection kits at 2, 6, and 12 months after their date of PCR test. The primary endpoint will be the urine-based KIT Score, based on the composite measurement of multiple DNA, protein and metabolite urinary biomarkers (reference). Secondary endpoints include NGAL and KIM-1 urinary biomarkers for kidney injury assessment.
Early detection of new or worsening kidney injury is urgently needed in order to implement preventative measures and target therapeutics that can minimize excess post-COVID19 kidney damage. A complete and standardized understanding of the trajectory and risk factors for kidney injury associated with COVID19+ disease is critical to informing the design and implementation of preventative and therapeutic strategies for COVID19-mediated kidney injury.
376 studies on the registry are indexed under Severe Acute Respiratory Syndrome; 15 are open to participants now.
This study's planned enrollment of 2,000 is above the median of 300 across 129 observational studies indexed under Severe Acute Respiratory Syndrome.

Individuals with current SARS-CoV-2 test result recorded in their electronic medical record (EMR) at a participating Academic Medical Center (AMC). EMR must also record: contact information (for inviting participation and mailing urine kits), age (to confirm 18+ years), race and sex (to balance COVID- vs. COVID+ samples), current serum creatinine (an outcome), history of kidney transplant or dialysis (ineligible), and hospitalization up to 4 weeks after SARS-CoV-2 test (ineligible).
By restricting eligibility to individuals not hospitalized within the month after their PCR test, the investigators study people at low risk of kidney injury, as the investigators survey a population of otherwise well people. This reflects the public health goal: To estimate excess risk of kidney injury among the >80% of COVID19-infected individuals in whom the infection resolves without intensive healthcare intervention, in order to unveil an otherwise silent health burden on society.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Control group to measure progression of AKI/kidney injury overtime
Other: Urine Collection
Study group to assess AKI trajectory/progression and associated risk factors of kidney injury with SARS-CoV-2 infection
Other: Urine Collection
A urine collection kit will be mailed to subjects' residence at 3 different timepoints over the course of 1 year to be returned to study team, upon which KIT score and other biomarkers will be assessed as outlined in the study design.
Continuous, Quantitative KIT Score
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.

Plan to share: No — Research records will be kept confidential to the extent permitted by law. Subjects will be identified by a code, and personal information from study records will not be released without the subject's permission. Study subjects will not be identified in any publication that may result from this study. However, the records may be reviewed under guidelines of the Federal Privacy Act by site monitors to assure the accuracy and completeness of study data. The investigators will make sure patient health information is removed from all the bio-samples and data obtained. The investigators will adhere to the NIH and HHS policies regarding the sharing of data and resources with the scientific community, publications, and intellectual property rights, and sharing of biomedical research resources.
