Urine pH may be monitored to help prevent the formation of kidney stones or to avoid side effects of some drugs, [68] such as high-dose methotrexate therapy, in which crystals that cause kidney damage can form if the urine is acidic. [69] If microscopy is performed, knowing the pH of the sample helps to identify any crystals that might be ...

Stomach acidity and dwell time may affect urine color intensity. [1] [2] [3] The presence of beet pigment-protecting substances, such as oxalic acid, in the meal and during intestinal passage, increase the color intensity in the urine. [1] Medications may affect stomach acidity, such as proton pump inhibitors, thereby affecting urine color. [2]
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 ...

[3] Medications that may cause urine to appear red include: Phenazopyridine [6] Nitrofurantoin [6] Doxorubicin [6] Rifampicin [6] Foods that may cause urine to appear red include: Blackberries [6 ...
Drug-induced glomerular disease is not common but there are a few drugs that have been implicated. Glomerular lesions occur primarily through immune-mediated pathways rather than through direct drug toxicity. Heroin and Pamidronate are known to cause focal segmental glomerulosclerosis; Gold salts therapy can cause membranous nephropathy [4 ...
Lipiduria (lipids in urine) can also occur, but is not essential for the diagnosis of nephrotic syndrome. A few other characteristics seen in nephrotic syndrome are: The most common sign is excess fluid in the body due to serum hypoalbuminemia. Lower serum oncotic pressure causes fluid to accumulate in the interstitial tissues.
