Calcium and phosphate are the most important minerals in your bones. Phosphate rises in renal failure and may cause itching. Calcium tends to fall. Albumin is an important protein in your blood. Low levels may indicate that you may be undernourished or that you have been unwell recently.
Potassium is a mineral that is normally removed by the kidneys and by dialysis.
Too high or low a potassium level may cause a disturbance to the rhythm of your heart. The kidney helps to maintain the balance of acid in the body. In renal failure the body retains too much acid and this causes a low level of bicarbonate in your blood. This is one cause of renal bone disease. Blood Pressure is the pressure produced by the heart to pump blood around the body.
