Posted on Fri, 6 Dec 2013

Question: i was just told i have hyparathyroidism. my calcium level is 11.1 and my pth level is 5,how can this be?

Brief Answer: Recheck labs Detailed Answer: May I know the upper limit of the normal range for the calcium on the lab report. This is important as it can vary sometimes from lab to lab. Also, were you fasting when you had this blood sample taken? Do you think you were dehydrated? Not fasting and/ or being dehydrated can elevate the calcium but this does not represent a disease state. However it is worth being XXXXXXX if you truly have a high calcium level or not. I sometimes order ionized calcium, along with intact PTH, 25 hydroxy vitamin D, phosphorus and magnesium, in order to ascertain the same. This should be done fasting but drink adequate water.

Brief Answer: Labs Detailed Answer: Okay. In such cases, I typically recommend the following tests (fasting and with good hydration) to confirm the presence of a truly high calcium : ionized calcium, along with intact PTH, 25 hydroxy vitamin D, phosphorus and magnesium

Brief Answer: Not typical Detailed Answer: Typically in (primary) hyperparathyroidism causing a high calcium level in blood, the PTH levels are not low like the one you have. It does not fit the picture and therefore repeat testing is necessary.

the lab had given me the wrong levels. calcium 11.4 and pth level 65.1

Brief Answer: that fits Detailed Answer: Now the labs are compatible with a diagnosis of primary hyperparathyroidism. You still need to see an endocrinologist as this condition requires a systematic thorough work up.
