  2. Assessment of kidney function - Wikipedia

    en.wikipedia.org/wiki/Assessment_of_kidney_function

    Blood tests are also used to assess kidney function. 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).

  3. Electrolyte imbalance - Wikipedia

    en.wikipedia.org/wiki/Electrolyte_imbalance

    Hypermagnesemia typically occurs in individuals with abnormal kidney function. This imbalance can also occur with use of antacids or laxatives that contain magnesium. Iatrogenic cases of hypermagnesemia can be prevented by avoiding magnesium-containing medications.

  4. Nephritic syndrome - Wikipedia

    en.wikipedia.org/wiki/Nephritic_syndrome

    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 ...

  5. Urine electrolyte levels - Wikipedia

    en.wikipedia.org/wiki/Urine_electrolyte_levels

    A sodium-related parameter is fractional sodium excretion, which is the percentage of the sodium filtered by the kidney which is excreted in the urine. It is a useful parameter in acute kidney failure and oliguria , with a value below 1% indicating a prerenal disease and a value above 1% suggesting acute tubular necrosis or other kidney damage.

  6. Nephrotic syndrome - Wikipedia

    en.wikipedia.org/wiki/Nephrotic_syndrome

    Acute kidney failure due to hypovolemia: the loss of vascular fluid into the tissues (edema) produces a decreased blood supply to the kidneys that cause a loss of kidney function. Thus it is a tricky task to get rid of excess fluid in the body while maintaining circulatory euvolemia.

  7. Kidney failure - Wikipedia

    en.wikipedia.org/wiki/Kidney_failure

    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 .

  8. Renal artery stenosis - Wikipedia

    en.wikipedia.org/wiki/Renal_artery_stenosis

    Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.This narrowing of the renal artery can impede blood flow to the target kidney, resulting in renovascular hypertension – a secondary type of high blood pressure.

  9. Albuminuria - Wikipedia

    en.wikipedia.org/wiki/Albuminuria

    Albuminuria is a pathological condition wherein the protein albumin is abnormally present in the urine (>30 mg per day). It is a type of proteinuria.Albumin is a major plasma protein (normally circulating in the blood); in healthy people, only trace amounts of it are present in urine, whereas larger amounts occur in the urine of patients with kidney disease.
