To other Labs running the DxH800s, are you seeing an increase in MCV delta failures without a reason like transfusion, elevated glucoses, etc.? We have been seeing an increase in delta failures and when the sample is recollected the MCVs check out. Also we are seeing an increase in MCVs with lower glucoses. We use to see MCV increases with elevated glucoses say in the 400 - 500 range. Now we are seeing it in the 200-300 range. Anyone else seeing this problem, please reply.
