Good afternoon Doctor.My wife is normally having low Haemoglobin, around 9, and low Platelet counts over last one year (between 100K and 46K) In tests done in Dec 17, Jan 18 the counts were around 60K to 70 k. But in early Feb 2018 when tests were done, Platelet count was reported at 150K. After a few days, re-tests were done when the result was 94K and in March it came down to 61K. Is such wide fluctuation in Platelet in a month s time possible, specially when she had no other treatment or illness during this period.
