This page is to help you understand all your numbers and enable you to discuss them with hospital staff. Too low a level of Hb is known as anaemia. Calcium and phosphate are the most important minerals in your bones. Phosphate rises in renal failure and may cause itching.

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.
