**4.8 Hypocalcaemia and hyperphosphataemia is prevalent in our crf patients**

In the study the mean serum calcium of CRF subject was 5.83± 2.1mg/dl. 37(71%) of CRF subjects had hypocalcaemia (<8.5mg/dl). This finding agrees with that of Slatoposky et al (1986). Calcium supplementation is a known modality for the treatment of hypocalcaemia. The mean serum phosphate of CRF patients in this was 6.1±2.0mg/dl. 41 (79%) had hyperphosphataemia (>4.5mg/dl). This agrees with finding of Slotoposky et al (1986) who demonstrated hyperphosphataemia even in moderate CRF. Dietary phosphate restriction and phosphate binding are effective methods of control of hyperphosphataemia.
