I am 38 healthy female freaking out over routine lab work calcium 10.7 protein 8.5 albumin 5.3 should i be worried about multiple myeloma? i have googled so much and so anxious. could it be dehydration? thanks?

"Dehydration" can contribute to the elevated calcium/protein/albumin values in your question, as all are calculated based on a measured amount of blood volume, which can exaggerate specific values.

The levels of these analytes can be afffected by your hydration state. You did not send normal values for you lab. Rather than rely on Dr. Google who can worry or even kill you I would invest the $ in a subscription to uptodate.com and read all about multiple myeloma. This will save you time, money and maybe even your life. Then discuss with your DR who knows you.

Your serum albumin& globulin levels are within normal limits. You are an age where serum calcium of 10.7 can be normal. Other than repeating your calcium level, a normal serum electrophoresis & immunofixation could rule out myeloma. A normal parathyroid hormone level can exclude hyperparathyroidism. Discuss this issue with your physician

Stop searching google and address all your questions to the doctor who ordered the test. One abnormal report does not mean mich unless co-related with other findings.
