Calcium Concerns

Doc,

Hoping you can shed your expert opinion on some recent lab issues that have occured.  I was recently diagnosed with ebv mono and have been going in for routine labwork.  When I was first diagnosed my chem panel was a little crazy.  Calcium - 10.8, Albumin 4.8, co2 31, and chloride 96.  All were either high or low.  On my next labwork 1 week later calcium - 9.8, albumin 4, co2 25, and chloride 100.  Is it possible thie calcium numbers are falsely elevated due to high albumin and dehydration?  I was definitely a little dehydrated and hydrated myself over the next week so I am not sure if I am masking a parathyroid issue or some other medical condition.  For a reference point I looked at lab work done back in march of this year and my numbers were calcium 10.3, albumin 4.4, chloride 98, and co2 27.  It seems every time my albumin goes up closer to high end of normal out of range my calcium is flagged as high.  The same goes for my co2.  When chloride drops co2 increases.  Do you think this requires further investigation or is hydration my main issue.  Not sure what came first the chicken or the egg as I have read high calcium can cause dehydration.  Thank you for your input.

Yes - calcium can change with higher albumin but looks like you run high-normal to slightly high calcium levels.  Would test PTH, calcium and possibly ionized calcium (at the same time) to further evaluate this for potential parathyroid over-function.
