Heather Watson says she has fully recovered from the illness that prematurely ended her US Open campaign.
Watson, 24, beat China's Chang Liu and Samantha Crawford of the United States in back-to-back matches on Saturday to qualify for the Wuhan Open.
It was the British number two's first singles appearances since undergoing medical treatment following her US Open defeat to Richel Hogenkamp last month.
"I got the blood test results and they're all fine," she said.
Guernsey-born Watson initially feared that she had suffered a relapse of glandular fever - which affected her in 2013 - after struggling in 80C heat and 59% humidity against Hogenkamp at Flushing Meadows.
