How does Citracal affect urine calcium test?
My doc ordered a 24-hour urine calcium test to test my calcium absorption. I'm currently taking 3 servings of Citracal a day and am trying to decide whether I should stop taking it while I do the test. The nurse at the lab and my doctor's nurse gave conflicting suggestions, and neither seemed confident in their answer.
In my view, the reasons to stay on Citracal for the test are:
- It might give me a better idea of whether the Citracal is actually being absorbed
- Any problems with calcium malabsorption are more likely to be detected if I'm eating lots of calcium
Reasons against include:
- Maybe being on Citracal will exaggerate the results and make it look like I'm malabsorbing calcium, when in fact I'm just giving my body a really high dose.
WebMD says: "You may be asked to follow a special diet that is either high or low in calcium for several days before the test." However, my doctor did not give any specific instructions in this regard.
