Targeted Surgical Tests: </li></ul><ul><li>Hematology : to exclude anemia, for platelets count & to assess the amount of blood may be needed during or after operation. </li></ul><ul><li>Creatinine & Electrolytes : state of dehydration & renal insufficiency. </li></ul><ul><li>Liver Function Tests : Alb & Protein guide to nutritional status & shows any clotting problems. </li></ul>
  13. 14. Investigations: <ul><li>ECG : It ’ s recommended in all patient >65years, pt. with blood loss & cardiovascular/pulmonary problems. </li></ul><ul><li>Urinalysis : used for determination of renal function, inflammation, infection & metabolic disorders. </li></ul><ul><li>Pregnancy Test : ( B- human chorionic gonadotrophin ) </li></ul><ul><li>HBsAg , HCV Antibodies & HIV testing. </li></ul>
  14. 15.
