Routine blood tests can only be used as a form of screening for uremia patients, but they cannot detect uremia. Patients with uremia can find out whether there will be a decrease in hemoglobin and whether there is anemia through routine blood tests, but before the diagnosis of uremia is confirmed, routine blood tests alone cannot accurately determine whether there is uremia. In order to accurately analyze whether there is uremia, first of all, we need to do routine urine examination, from which we can analyze whether there is proteinuria, whether there are red blood cells, white blood cells, etc.; and then we can judge whether there is uremia by doing biochemical examination, including blood creatinine and glomerular filtration rate. Diagnosis of uremia, also need to do abdominal ultrasound, CT and radionuclide nephrogram and so on. If it is clear through the examination that there is uremia, it is necessary to carry out regular treatment as soon as possible to avoid delaying the condition.
