Testing for renal osteodystrophy involves taking a blood sample to measure your levels of calcium, phosphorus and PTH. If you are on dialysis, calcium and phosphorus tests are done on a monthly basis (or sometimes more frequently). PTH is measured quarterly for most patients—although testing may be done more frequently for people just starting vitamin D therapy or those with severe bone disease while the healthcare team is determining the correct dosage of vitamin D. Your renal dietitian will review your lab results and recommend changes in your diet or change your phosphorus binder prescription. The goal of treating renal osteodystrophy is to restore balance between calcium, PTH, phosphorus and vitamin D in the body.glomerular malfunction is the most common and usually corresponds to a urinary protein excretion of more than 2 g per 24 hours. When a quantitative measurement of urinary protein is needed, most physicians prefer a 24-hour urine specimen. However, the urine protein-to-creatinine ratio performed on a random specimen has many advantages over the 24-hour collection, primarily convenience and possibly accuracy. Most patients evaluated for proteinuria have a benign cause. Patients with proteinuria greater than 2 g per day or in whom the underlying etiology remains unclear after a thorough medical evaluation should be referred to a nephrologist.
