@beanie300 I checked and found a study about genetic links for hyperparathyroidism. It talks about several different gene mutations that cause different types of hyperparathyroidism so it sounds like some forms of it can be inherited. However, just because a person may have genes to predispose them to something, the genes might not be expressed unless other criteria are met in the body chemistry which is complex.

Here are some links and a study regarding parathyroid disease and genetics. This information talks about high calcium levels in both blood and urine as indicators of a problem. I think only a doctor can really answer what is best in your case, but you can ask questions from this information. I think calcium levels are normal things that are routinely checked in blood and urine tests.

This link shows diagnosis in relation to blood levels of calcium and parathyroid hormones shown in a table.

By clicking the links, they even had an app developed by doctors for diagnosing parathyroid disease. http://calciumpro.com/

There is also a rare condition that causes high blood calcium, but it isn't caused by the parathyroid gland called FHH - Familial Hypocalciuric Hypercalcemia.
