I just inquired about that with my local health provider, since I might have had it in March, just as the Corona started to spread seriously in Europe.
They could book me a time for antibody testing, but they also believed that the antibody (serological) test wouldn't say anything, because the antibodies seems to disappear within six months. AIUI, you still have some protection after the antibodies recede due to the different immune systems, but would still be at risk of being infected again.
