I think at those levels a 28k drop is normal fluctuation and nothing at all to worry about. Supposedly the counts are only accurate plus or minus 10k so those numbers are barely different. Also, those who have a full remission from Rituxan (normal counts) are very likely to have a sustained remission (of multiple years).
There are many on the board whose counts are affected by colds and such - but some have counts that drop and others have counts that rise! My theory is it depends on the mechanism behind your ITP, what really causes it in your body. Personally my counts are not affected by colds.
Pretty soon you'll only be checking monthly, won't that be nice?
