Urine examination items are mainly white blood cells, red blood cells, urine sugar, ketone bodies and other items to check, specifically the following: 1, white blood cell examination: the main check the number of white blood cells in urine, in general, normal urine rarely appear white blood cells, centrifugation after high magnification field of view will not exceed 5, if there are a large number of white blood cells, more suggestive of urinary tract inflammation, such as pyelonephritis, urethritis, cystitis, etc. If there is a large number of white blood cells, it mostly indicates urinary tract inflammation, such as pyelonephritis, urethritis, cystitis, etc., and requires further examination. 2, red blood cell examination: also known as “occult blood”, if a large number of red blood cells found in the urine, suggesting a hemorrhagic lesion, mostly seen in the urinary tract stone stimulation, various types of inflammatory stimulation, tumor lesions, glomerular disease, etc. 3, urine sugar: this indicator is abnormal, suggesting that patients with elevated blood sugar or kidney disease renal sugar threshold decline may,. 4, urine ketone body: more with urine sugar items together with the analysis of lesions, mainly suggesting diabetic ketosis, poisoning, etc., but also starvation urine ketone, need to be combined with the patient’s other symptoms and other examination items comprehensive analysis. 5, urinary nitrite: mainly suggests pyelonephritis, cystitis. 6.Urobilinogen, urinary bilirubin: mostly suggest bile metabolism problem, may have cholecystitis, hepatobiliary tumor, hepatitis and other lesions, if the abnormality is obvious, need to combine with the hepatobiliary system examination situation analysis. 7, urine specific gravity, acid-base: mainly look at the specific gravity of urine and acid-base situation, to clarify the patient’s blood volume, acid-base problems. 8, urine protein: pathological urine protein mainly suggests nephritis, also need further examination to clarify the diagnosis. In short, urine routine is one of the routine and convenient examination items, regular physical examination, you can find out the abnormalities of the body from the small changes.
