Results that typically require microscopic examination include abnormal color or clarity and positive dipstick results for blood, leukocytes, nitrite, or protein. [ 90 ] If microscopy is necessary, the urine may be centrifuged to concentrate the solid elements so that they can be viewed more easily.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

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 ...
Leukocytosis is a condition in which the white cell count is above the normal range in the blood. [1] [2] It is frequently a sign of an inflammatory response, [3] most commonly the result of infection, but may also occur following certain parasitic infections or bone tumors as well as leukemia.
Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer).
Faecal calprotectin (or fecal calprotectin) is a biochemical measurement of the protein calprotectin in the stool. Elevated faecal calprotectin indicates the migration of neutrophils to the intestinal mucosa , which occurs during intestinal inflammation, including inflammation caused by inflammatory bowel disease .
