I do not know, but here in Germany all
testing centres (and almost all other things except supermarkts, pharmacies and restaurants) are already closed.
I think for first time until 20 April, later they (government) may extend the time again or may not, depends on corona situation.
The idea behind it that there is a luck in medicine which cant care for very much people at the same time, so they want to slow growth, so that every patient earlier or later has chance to become needed medical treatment
