Reference ranges for urine tests are described below: Measurement Lower limit Upper limit ... RBC casts: n/a 0 / negative [2] White blood cells (WBCs) 0 [2] 2 [2] pH ...
Urine urobilinogen is increased in liver disease and hemolytic jaundice (jaundice due to increased destruction of red blood cells); in the latter case, urine bilirubin is typically negative. In bile duct obstruction, urine bilirubin increases but urobilinogen is normal or decreased, as bilirubin cannot reach the intestines to be converted to ...
The normal number of red blood cells in urine should not usually exceed 3 per high power field. [13] A urine test strip showing positive for blood can also indicate hemoglobinuria, which is not detectable using a microscope due to the lysis of red blood cells in the urinary tract (particularly in alkaline or dilute urine), or intravascular ...
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]
All values in Hematology – red blood cells (except hemoglobin in plasma) All values in Hematology – white blood cells; Platelet count (Plt) A few values are for inside red blood cells only: Vitamin B 9 (folic acid/folate) in red blood cells; Mean corpuscular hemoglobin concentration (MCHC)
Many urine tests (urinalysis) monitor the amount of urobilin in urine, as its levels can give insight on the effectiveness of urinary tract function. Normally, urine would appear as either light yellow or colorless.
In urine cytology, collected urine is examined microscopically. One limitation, however, is the inability to definitively identify low-grade cancer cells and urine cytology is used mostly to identify high-grade tumors. [4] If the test detects atypical or cancerous cells, further tests may be recommended, such as cystoscopy and a CT scan.
