Little information is available on the relationship between serum C reactive protein with albumin, urea, creatinine, sodium, potassium and phosphate levels for patients with Acute Renal injury. The sample of this study consists of 30 patients and 30 apparently healthy individuals. The results showed that the levels of C reactive protein, urea, creatinine, potassium and phosphate marked increase in (all patient groups) regardless to their age in compare with (control group) (P≤0.05).While levels of Albumin and sodium shows marked decrease in all patients group regardless to their age in comparison with the control group (P≤0.05). It was found positive relationship between C reactive protein and levels of each urea, creatinine, potassium and phosphate. Also it was found negative correlation between C reactive protein and levels of the albumin and sodium.
