Are platelet decreases varying depending on the hour of day, for a patient with thrombocytopenia?

Hard to say. This is hard to say as many cases are asymptomatic and found by CBC or complete blood count. Things like easy bruising with minor trauma, nosebleeds, and even just weakness are often noted. On inspection signs like petechiae or ecchymoses indicate bleedind as well as slow bleeding from wounds. Bruises would mean a count at or below 50000/mm3. Any of these signs seen often should get a dr. Appt.
