Positive Tests Over Time, by Region and County
* as of 4/5/22, test percent positivity is calculated using PCR tests only
- Test results data comes from the Electronic Clinical Laboratory Reporting System (ECLRS), a NYSDOH database that contains reported results from all the labs testing samples from New York State residents. Starting on September 20, 2020, these data also include pooled/batch tests reported by institutions of higher education. Self-administered home tests reported to counties are not included in these data.
- However, from December 30, 2021 until March 30, 2022, 24% of positive results from Onondaga County (Central New York region) were from self-administered home tests.
- Positive results on this page represent the first time a person tested positive in New York State. Thus, the information here represents the number of unique persons who have tested positive. Reinfections, or a new positive result 90 days after a first positive result, do rarely occur. In late 2021, the frequency of reinfections increased. Please see our Reinfections Dashboard for more information and data on this topic.
- As of 4/4/22, HHS no longer requires entities conducting COVID testing to report negative or indeterminate antigen test results. This may impact the number and interpretation of total test results reported to the state and also impacts calculation of test percent positivity. Because of this, as of 4/5/22, test percent positivity is calculated using PCR tests only. Reporting of total new daily cases (positive results) and cases per 100k will continue to include PCR and antigen tests.
