Lari also announced more than 2,000 new coronavirus infections, in line with a recent surge in cases that President Hassan Rouhani attributed to increased testing.
"When more tests are done, then naturally more cases are identified," Rouhani told a televised meeting of his cabinet.
But the high number of recent cases "does not have a negative aspect to it, and people should not worry", he added.
The ministry said it has carried out more than 1,151,000 COVID-19 tests since it reported the country's first cases on February 19.
The Health Ministry spokeswoman said the 2,011 infections confirmed from Tuesday to Wednesday had raised Iran's overall caseload to 177,938.
Of the new cases detected, 811 patients were admitted to the hospital, she added.
At least 140,590 patients have recovered from the coronavirus infection so far and have been discharged from hospitals across Iran, the spokeswoman added.
Iran has been among the countries hit hard by the coronavirus that first showed up in China in late December 2019 before spreading across the globe.
Inhumane US sanctions have hampered the virus battle in Iran, which reported its first COVID-19 infection cases in late February.
However, Iran’s Health Minister Saeid Namaki hailed Iran's handling of the coronavirus pandemic, saying the country has turned from an importer of medical items into an exporter despite the illegal US sanctions.
He made the remarks in a videoconference call to the inauguration of a factory in Markazi Province, which produces acetaminophen and pharmaceutical raw materials, the first of its kind in the West Asia.
Namaki said that Iran saved 700 million euros in the last Persian calendar year by relying on local production of medicine and pharmaceuticals.
"Most importantly, as a sanctions-hit country subjected to oppressive bans, we were able to manage the coronavirus outbreak and within 60 days turn from an importer of medical equipment and necessary items such as masks into a manufacturer and later an exporter," he said.
"It was another sign of great honor that will shine in the history of the country, which at the height of the sanctions, was able to get itself together in less than two months and turn into an exporter of masks, medicine, and disinfectants," he added.
