Uremia is the final state of chronic renal failure. This disease cannot be diagnosed through physical examination and medical history inquiry alone. Diagnosis requires testing, combined with the patient's physical examination and medical history, to comprehensively determine the diagnosis. Patients with uremia first need to have a blood test to check kidney function, with blood creatinine levels needing to exceed 707μmol/L. Secondly, they should undergo an ultrasound of the urinary system. Typically, the kidney size in such patients is reduced, which can be detected by the ultrasound. These two diagnostic methods used together can diagnose uremia. Patients also need to be checked for potential complications caused by uremia, such as measuring blood pressure and performing a complete blood count to check for renal anemia, among others.
