Hi Margarete,
You know it is not only the platelet count that is important but the platelet function too. In MDS the platelets can be dysfunctional (mine are dysfunctional) so to assess the bleeding risk there is a test called PFA 100 (Platelet Function Analyzer).

As you understand it is difficult to know when there is a risk for bleeding if you only measure the platelet count but most clinics don't give platelet transfusions if the patient has a platelet count of 20 or more. If the patients has severe bleedings from nose, mouth, rectum and so on they often give platelet transfusions even if the platelets count is higher.
Kind regards
