A routine blood test usually only test for some general features, like potassium, sodium, creatinine, urea, C-reactive protein and a few other. It does often make a blood count of both red blood cells and white blood cells too. In that way it can detect leukemia.
For that reason, routine blood and urine tests are especially important. They detect blood or protein in the urine and abnormal levels of certain waste products in the blood, such as creatinine and urea (blood urea nitrogen or BUN), which are early signs of kidney dysfunction. The following problems may, however, be warning signs of kidney disease and should not be ignored. Prompt medical attention is required when any of these are present: 1  Swelling or puffiness, particularly around the eyes or in the face, wrists, abdomen, thighs or ankles.  Urine that is foamy, bloody, or coffee-colored.
