COVID-19 Testing Dashboards

Due to a significant and unresolved problem with the State of California’s CalREDIE reporting system, the County of Santa Clara Public Health Department, as well as county public health departm​ents statewide, are experiencing significant underreporting of COVID-19 testing results.  Because of this problem, the information presented in this dashboard/these dashboards since mid-July 2020 is incomplete.  We will provide updates on the status of these reporting delays as soon as they are available.  Additional information about these delays may be available from the State of California. 

This dashboard provides the total daily testing for COVID-19 in Santa Clara County.  We monitor testing to ensure enough tests are completed to slow the spread of COVID-19. With adequate testing, the Public Health Department can help isolate those who test positive and use contact tracing to notify anyone who may have been exposed. The average turnaround time is the average number of days between a specimen being collected for testing and the result of that test being reported to the Public Health Department. When the turnaround time is shorter, the Public Health Department is able to isolate cases and identify and quarantine contacts quicker – a crucial part of successful case investigation and contact tracing.

Data Notes: A test represents at least one specimen tested per person per day. Some people will have multiple specimens collected and tested during the same visit but are only counted once per day. If a person is tested multiple times on different days then he or she will be counted for each day he or she was tested. The test positivity rate is the percent of positive tests out of total tests performed. The 7-day average positivity rate represents the most recent daily positivity rate averaged over the prior seven days. The test positivity rate highlighted in the top banner of the dashboard has a 7-day lag, because data for the last 7 days are preliminary and will likely change as additional results are received. The average turnaround time is the most recent 7-day average number of days between the day a specimen is collected and the day the test result  is reported to the Public Health Department​.

Healthcare System Testing Dashboard

Due to a significant and unresolved problem with the State of California’s CalREDIE reporting system, the County of Santa Clara Public Health Department, as well as county public health departments statewide, are experiencing significant underreporting of COVID-19 testing results.  Because of this problem, the information presented in this dashboard/these dashboards since mid-July 2020 is incomplete.  We will provide updates on the status of these reporting delays as soon as they are available.  Additional information about these delays may be available from the State of California. ​

Testing by healthcare system
This dashboard summarizes the number of COVID-19 tests performed by major healthcare systems in the county. Each ‘test’ or ‘testing incident’ represents at least one specimen tested per person, per day. This does not represent the number of individuals tested, as some people are tested multiple times over time because of the risk of frequent exposure.

Why this is important
Testing by healthcare systems, such as hospitals and clinics, is one of the key ways to ensure sufficient testing is available and accessible for the patients they serve. Healthcare providers in the county are required to test individuals with COVID-19 symptoms, contacts to a case and asymptomatic people who have a greater risk of being exposed to COVID-19. Hospitals are also testing people who receive select non-COVID related healthcare services at their facilities. Sufficient levels of testing in healthcare systems helps break chains of transmission and slow or prevent the spread of disease in the community.

Data notes: These data represent testing among Santa Clara County residents and so may not represent all testing performed by healthcare systems, given that some systems also serve people residing outside the county. Healthcare systems with outpatient services tend to serve more people and so may have higher testing levels than healthcare systems with only inpatient and emergency department services. Some healthcare systems in the county offer outpatient services only. The number of tests measures the total number of COVID-19 molecular tests completed during the seven-day time period. The daily average number of tests represents the seven-day average count of tests. The daily average rate of tests is the daily average number of tests completed over the past 7 days per 100,000 people served by the individual healthcare system. Total tests since January is the cumulative count of tests completed by the healthcare system since that time. The average rate of tests is not calculated for Verily and OptumServe sites. The State of California has defined an initial goal of at least 150 tests per day per 100,000 people. Bay Area County Health Officers set a goal of 200 tests per day per 100,000 people. Laboratories are required to report both positive and negative COVID-19 results via the California Reportable Disease Information Exchange (CalREDIE). The data for this dashboard are compiled using testing reports submitted to CalREDIE. The data are presented with a 7-day lag due to reporting delays. Please note that the Public Health Department is working with the healthcare systems in the county to improve reporting in CalREDIE and decrease under-reporting of tests completed.
