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 sepsis, or in older people with pneumonia.
The leukocyte esterase test indirectly detects the presence of leukocytes (white blood cells) in urine which can be associated with a urinary tract infection. In the elderly, the leukocyte esterase test is often positive even in the absence of an infection.
The clarity of urine is also recorded during urinalysis. Urine is typically clear; materials such as crystals, cells, bacteria, and mucus can impart a cloudy appearance. [26] A milky appearance can be caused by a very high concentration of white blood cells or fats, or by chyluria (the presence of lymphatic fluid in the urine). [34]
A sample of urine sediment from a patient suffering from a urinary infection, it is possible to see leukocytes (small round and granular), erythrocytes (small round and biconcave) and epithelial cells (large and polyhedral). The test for leukocyte esterase is indicative and does not replace microscopic examination of urine. [19]
Urethral syndrome is defined as symptoms suggestive of a lower urinary tract infection but in the absence of significant bacteriuria with a conventional pathogen. [1] It is a diagnosis of exclusion in patients with dysuria and frequency without demonstrable infection. [2] In women, vaginitis should also be ruled out. [3]
Leukocyte esterase (LE) is an esterase (a type of enzyme) produced by leukocytes (white blood cells). 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 ...

Glitter cells (also called Sternheimer-Malbin positive cells) are polymorphonuclear leukocyte neutrophils with granules that show a Brownian movement and that are found in the urine, most commonly associated with urinary tract infections or pyelonephritis and especially prevalent under conditions of hypotonic urine (samples with specific gravity less than 1.01).
