These include tests that are intended to directly measure the function of the kidneys, as well as tests that assess the function of the kidneys by looking for evidence of problems associated with abnormal function. One of the measures of kidney function is the glomerular filtration rate (GFR). Other tests that can assess the function of the ...
Primary causes of nephrotic syndrome are usually described by their histology: [21] Minimal change disease (MCD): is the most common cause of nephrotic syndrome in children. It owes its name to the fact that the nephrons appear normal when viewed with an optical microscope as the lesions are only visible using an electron microscope. Another ...
Chronic kidney disease (CKD) is a type of long-term kidney disease, in which either there is a gradual loss of kidney function which occurs over a period of months to years, or an abnormal kidney structure (with normal function).
What causes kidney disease? The most common causes of CKD are high blood pressure and diabetes, "which damage the small blood vessels and filtering units in the kidneys over time," says Nagata ...
Diabetic nephropathy, also known as diabetic kidney disease, [5] is the chronic loss of kidney function occurring in those with diabetes mellitus. Diabetic nephropathy is the leading causes of chronic kidney disease (CKD) and end-stage renal disease (ESRD) globally. The triad of protein leaking into the urine (proteinuria or albuminuria ...
Antinuclear antibody (ANA) titer - ANA is commonly positive in patients who have an underlying autoimmune disease, so this test is useful if the physician suspects an underlying autoimmune disease (refer to the Causes section above for examples) as the cause of the presenting nephritic syndrome. If positive, then the physician may order ...
Acute kidney injuries can be present on top of chronic kidney disease, a condition called acute-on-chronic kidney failure (AoCRF). The acute part of AoCRF may be reversible, and the goal of treatment, as with AKI, is to return the person to baseline kidney function, typically measured by serum creatinine .
Hypouricemia is often benign and not a medical condition, but it is a useful medical sign. It is known occasionally to result in a decreased ability to concentrate urine due to decreased hypertonicity of the renal medulla, and may contribute to hypotension when other risk factors are present.
