The Arizona Department of Health Services is releasing daily updates on the number of COVID-19 tests administered across the state. The state has reported more than 55,000 tests administered in about eight weeks. In the last week of February, the state had only administered four tests.

Health Services has changed the way the testing data is reported as of the afternoon of April 20. The department now gives the increase and the total percentages.


As of April 21, the state reports that of the 55,152 tests administered, 90.48% have yielded a negative result, based on data of the the number of confirmed cases and tests.

State health officials have said the state is facing a shortage of tests, like other states across the nation. The state has said it is prioritizing tests for the most vulnerable populations, including individuals over 60 and those with underlying health conditions.

People aged 65 or older or those who have at least one chronic health condition make up 72% of those who have been hospitalized and 97% of deaths for COVID-19.

Maricopa County, the largest county in Arizona with more than 4 million people, has had the highest number of tests administered, according to the state. The county also reports the highest number of confirmed COVID-19 cases. The state has reported that people ages 20-44 have been administered the most tests of any other age group across Arizona.

Since late February, the number of tests administered in Arizona has soared.
