Health officials say there are now 18 diagnosed cases of COVID-19 in the state.
The Arizona Department of Health Services posted the new figure on it's website Monday.
Six of the new presumptive cases were found through testing from a commercial laboratory, not a state lab.
The agency said via Twitter that it recently expanded testing to third-party entities.
The department is also no longer reporting the number of pending tests. Third-party labs are not required to disclose those to the state.
Eight of the cases are in Maricopa County, five in Pinal County, four in Pima County and one in Graham County.
There are still no reported cases in northern Arizona.
