Levels of calcium phosphorus, vitamin D3, vitamin D3 analogues, and intact parathyroid hormone (PTH) from December 1999 to October 2001 in a patient receiving dialysis.asterisk3IVCRV333

Left nephrectomy was performed on 8 August 2001 ( ). Levels of vitamin D in the inferior vena cava ( ) and renal vein ( ) were measured by Quest Diagnostics Laboratory, Nichols Institute, San Juan Capistrano, California. Normal ranges were as follows: calcium, 8.0 to 10.4 mg/dL; phosphorus, 8.4 to 10.2 mg/dL; PTH/20, 0.65 to 3.4 pg/dL; vitamin D , 15.9 to 55.6 pg/mL; vitamin D (IVC and RV), 15 to 60 pg/mL. To convert calcium values to mmol/L, multiply by 0.25; to convert phosphorus values to mmol/L, multiply by 0.3229; to convert vitamin D values to pmol/L, multiply by 2.6. PTH values were divided by 20 to allow plotting on the graph.
