Dont quote me, but I believe that has to do with coolant. By no means am I telling you what to do, but I always send my oil samples to CAT for analysis. They give a much more detailed report and break down, and if there are any items which appear to be "higher than normal" they will give explanation of why they might be and where it might come from. Just food for thought.
iirc calcium is an oil additive. It will vary with different brands. Go here click on the gas/diesel tab and hover your mouse over each category to get an explanation of what they mean. http://www.blackstone-labs.com/report-explanation.php
Calcium is an additive that acts as a detergent at high temperatures. High calcium means that you did not degrade your detergent yet. It is a good thing, unless you use a cheap oil and it has a high calcium component to battle its other inherit weaknesses.
