My teenage daughter was recently found to have a calcium of 10.5 mg/dl. The lab says this is high, and her doctor says that she probably needs surgery to remove a parathyroid tumor. What do you think?

A calcium of 10.5 mg/dl (2.62 mmol/l) is normal for a teenager. Teenagers have higher calcium levels than older adults. While a calcium of 10.5 would definitely be high for a 50 year old, it is within the normal range for children and teenagers. Your daughter’s lab is not correcting for her age.
Her calcium level does not indicate a parathyroid tumor, and so she does not need surgery.
