RCA is a CT scan of the right coronary artery. A high RCA score would indicate levels of plaque accumulated in the cardiac artery. And is frightening for the risk of stroke and cardiac arrest.
Patients with high urinary calcium and normal serum calcium levels, in the main, are absorbing too much calcium in the intestine. This can happen in between doses of Tymlos because pth makes good use of D3. Pth is in the serum for 4 hours and in between the absorbed calcium is excreted through the kidneys. A person with hypercalicuria and normal serum calcium usually has a good parathyroid gland and is at greatest risk for kidney stones. Prolonged hypercalicuria poses additional risk for kidney function.
It would be unusual to have a second RCA CT so soon after a normal CALC score.
Thank you for the warning that saves others from the risk.
I'm a little confused about which tests you had. If you feel like clarifying, I'd know which test to take to protect myself.
