Pyuria. White blood cells seen under a microscope from a urine sample. Pyuria is the condition of urine containing white blood cells or pus. Defined as the presence of 6-10 or more neutrophils per high power field of unspun, voided mid-stream urine, it can be a sign of a bacterial urinary tract infection. Pyuria may be present in people with ...
Blood in the urine and occasional RBC casts [20] Sterile pyuria: white blood cells and no bacteria. About 50% of patients with AIN have pyuria. [21] Nephrotic-range amount of protein in the urine may be seen with NSAID-associated AIN. Low grade proteinuria may be seen in a majority of other causes of AIN. [21]
Phase-contrast microscopic image showing many bacteria and white blood cells in the urine. These changes suggest a urinary tract infection. These changes suggest a urinary tract infection. Microorganisms that can be observed in the urine include bacteria, yeast and Trichomonas vaginalis . [ 129 ]
Analysis of the urine may show signs of urinary tract infection. Specifically, the presence of nitrite and white blood cells on a urine test strip in patients with typical symptoms are sufficient for the diagnosis of pyelonephritis, and are an indication for empirical treatment. Blood tests such as a complete blood count may show neutrophilia.
Another test, urine microscopy, looks for the presence of red blood cells, white blood cells, or bacteria. Urine culture is deemed positive if it shows a bacterial colony count of greater than or equal to 10 3 colony-forming units per mL of a typical urinary tract organism. Antibiotic sensitivity can also be tested with these cultures, making ...
A leukocyte esterase test (LE test) is a urine test for the presence of white blood cells and other abnormalities associated with infection. White blood cells in the urine can indicate a urinary tract infection (UTI). Positive test results may be clinically significant in the right context. The LE test is also used to screen for gonorrhea and ...
Historically, nephritic syndrome has been characterized by blood in the urine (hematuria), high blood pressure (hypertension), decreased urine output <400 ml/day (oliguria), red blood cell casts, pyuria, and mild to moderate proteinuria. [8][9] If the condition is allowed to progress without treatment, it can eventually lead to azotemia and ...
An excess of white blood cells is usually due to infection or inflammation. Less commonly, a high white blood cell count could indicate certain blood cancers or bone marrow disorders. The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count.
