Urinalysis labs include urine specific gravity, proteinuria, urine sugar, urine ketone bodies, urine bilirubin and urine bile, red blood cells and white blood cells. 1. urine specific gravity: urine specific gravity (morning urine) normal value of 1.015 ~ 1.025. Increased in blood volume, diabetes mellitus, etc.; decreased in a large number of drinking water, uremia, etc.. 2. Proteinuria: Normal people excrete very little protein in the urine every day (30~130mg), when the protein concentration is greater than 100mg/L or 150mg/24h, the urine with positive protein characterization is called proteinuria. Proteinuria is mostly seen in acute nephritis, pyelonephritis, diabetic nephropathy, after strenuous exercise, etc. 3. Urine sugar, urine ketone body: urine sugar qualitative test is positive urine is called diabetes. Glycosuria can be seen in diabetes mellitus, nephrotic syndrome and so on. It is possible to have positive urine ketone bodies in cases such as starvation, as well as in diabetic ketoacidosis. 4. Urinary bilirubin and urobilinogen: Urinary bilirubin and urobilinogen are mainly used for the identification of jaundice. In hepatocellular jaundice, urobilinogen and urobilirubin are generally positive; in hemolytic jaundice, urobilinogen is generally positive and urobilirubin is negative; in cholestatic jaundice, urobilirubin may be positive and urobilinogen is mostly negative. 5. Erythrocytes: Erythrocytes represent urinary bleeding. Non-homogeneous red blood cells can be seen in glomerular diseases, and homogeneous red blood cells can be seen in places other than glomeruli. 6. Leukocytes: Leukocytes are mainly used in the diagnosis of urinary tract infections, such as pyelonephritis and cystitis. It is recommended to go to regular hospitals for further consultation with relevant doctors.
