The presence of hematuria, or blood in the urine, may indicate acute UTIs, kidney disease, kidney stones, inflammation of the prostate (in men), endometriosis (in women), or cancer of the urinary tract. In some cases, blood in the urine results from athletic training, particularly in runners. [citation needed]
Hematuria can be classified according to visibility, anatomical origin, and timing of blood during urination. [1] [6]In terms of visibility, hematuria can be visible to the naked eye (termed "gross hematuria") and may appear red or brown (sometimes referred to as tea-colored), or it can be microscopic (i.e. not visible but detected with a microscope or laboratory test).
Kidney stone disease; Other names: Urolithiasis, kidney stone, renal calculus, nephrolith, kidney stone disease, [1] A kidney stone, 8 millimeters (0.3 in) in diameter: Specialty: Urology, nephrology: Symptoms: Severe pain in the lower back or abdomen, blood in the urine, vomiting, nausea [2] Causes: Genetic and environmental factors [2 ...
The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer.

This is accomplished by urinalysis, measurement of urine protein excretion, kidney imaging, and, if necessary, kidney biopsy. [1] Much of renal physiology is studied at the level of the nephron – the smallest functional unit of the kidney. Each nephron begins with a filtration component that filters the blood entering the kidney.
"Seeing blood in the urine is another thing often reported." Some kidney stone patients may experience fever and chills as well. Related: The Best Habit for Healthy Kidneys, According to Nephrologists
The glomerular basement membrane is a tissue in the kidney that filters the blood. An abnormal glomerular basement membrane may allow red blood cells into the urinary space. Because kidney stones are so common in people with LPHS, crystals in the kidney tubules may also play a part in bleeding and pain. [4] Other speculations on cause include [5]
Three different tests may be used to measure calcium levels in urine, 24-hour urine tests, blood tests, and genetic tests. Measuring calcium levels can also be done using an oral calcium tolerance test. [24] Ultrasound and CT scans of the urinary tract can be done to diagnose kidney stones or kidney abnormalities as IH often accompanies it.
