I get a discrepancy in calcium levels when using the Ca test kit and strontium test kits from Salifert of about 25. While I realize it is not a big discrepancy, I would expect then to be the same. I am guessing the lower reading of the strontium kit is more accurate as the test sample is 2.5 times the size. I have had several of each kit with the same results. Does anyone else get the same results?
