... to twice the upper limit of normal. In contrast, 36 patients with a creatinine clearance below < 20 ml/min had an 80% elevated iPTH, up to 5 times the upper limit of normal. The patients with ERF and elevated iPTH had a lower serum calcium but no higher serum phosphate than those with normal iPTH...

... of animals, a reverse linear relationship was noted between the serum phosphate level and the tubular fluid bicarbonate concentration (TFHCO 3 ). For the intact dogs, TFHCO 3 = 32.27 SUFp ± 2.17, r = 0.715, p = 0.02, and for the TPTX dogs, TFHCO 3 = 35.68 – 2.39 SUFP ± 2.26; r = 0.619, p < 0.02...
