This is a new one for me (after 30 years!) An ER patient presented recently with a MCV of 107 and low MCH, MCHC. This patient was in house at our hospital just last week, with all normal indices. Called the RN in ER who commented that she is expected to have a very high glucose. Googled it and sure enough, hit a few articles like this;

The patient had a glucose over 1400 g/dl. My question is this: for those of you who are aware of this phenomenon, do you attempt a correction and report that out? Apparently this is a in vitro pj=henomenon related to hyperosmolality when the blood sits in the EDTA tube before processing on the ananlyzer. The "cure" is to do a saline replacement and let it sit a bit.
Thanks, Scott
