I came across a very valuable paper in Clinica Chimica Acta on the stability of hematology controls for MCV. (Some of you are already guessing what this is going to be about...)
If you take a hematology control, how many SDs should you expect to see it shift at week 5 of use versus the first week of use? In other words, what is the SDI you should expect?
- 1 SDI
- 2 SDI
- 3 SDI
- 4 SDI
- 5 SDI
- higher than 5 SDI
The answer, after the jump...
