A sharp rise was also recorded in Lothian, from 11 to 20.
To date 3,229 tests have been carried out.
Health Secretary Jeane Freeman has asked health boards to detail their plans to increase capacity in hospitals ahead of the expected increase in the number of cases.
Ms Freeman said: "We have been clear from the outset about the challenges our health service is going to face in the weeks and possibly months to come.
"With our focus very much on seeking to delay the spread to reduce the peak impact and protect the most vulnerable, planning around NHS capacity is vital."
She added that non-urgent care would be scaled down over the next two to three weeks in a bid to double intensive care capacity.
Ms Freeman will make a further statement to the Scottish Parliament on Tuesday.

First Minister Nicola Sturgeon said on Thursday that widespread school closures were not yet necessary - but from next week restrictions would be placed on gatherings of more than 500 people because of the demands these would place on frontline staff such as ambulance crews.
Earlier, national clinical director Jason Leitch, told BBC Scotland the guidance over mass gatherings had been a judgement call in order to ensure "we have all the staff and equipment we could possibly need" rather than a bid to halt the virus spreading.
Mr Leitch said there were no current plans to close schools and this would only change, "when we come to the point when science tells is it is the right thing to do".

Witnesses who are unfit should, if possible, obtain a "soul and conscience certificate" which can be emailed to the court, otherwise they risk being the subject of an arrest warrant.
