Lab results show PTH is 173 pg/ml. Does this indicate cancer or kidney disease?

Hello. Thanks. Could the following lab test results show any possible indication of either cancer or kidney disease as the primary diagnosis? If so, can cancer or kidney disese still be possible (or likely) in addition to HyperParathyroidism as the primary diagnosis? Glomerular Filtration 33 Calcium 12.4 mg/dL Ionized Calcium 1.58 mmol/L PTH (whole molecule) 173 pg/ml Phosphorouus 2.0 mg/dL Potassium 4.9 mmol/L Magnesium 1.0 mg/dL

Hello and welcome to HCM,

First of all I would like to comment on your electrolyte profile:
1. GFR is reduced
2. Total calcium is raised slightly and ionized calcium is reduced
3. Phosphorus is slightly on lower side
4. Potassium is normal
5. Magnesium is slightly on lower side
6. Parathormone is very much increased

This profile suggests hyperthyroidism and elevated levels of parathormone.
Raised levels of parathormone is seen in parathyroid malignancy.
Raised level of total calcium and lower levels of phosphorus potentiate hyperparathyroidism.

Consult your doctor for further investigation to establish the diagnosis.
Sestamibi scan is helpful in establishing the diagnosis.
But first consult your doctor for further work up.

Thanks and take care
