Creatinine, 24 Hour details
What Creatinine, 24 Hour shows
Creatinine is a waste product from normal muscle activity that the kidneys filter out at a fairly steady rate. In a 24-hour urine collection, measuring total creatinine helps confirm the collection was complete, since an unusually low amount often means some urine was missed. It is also used with blood creatinine to calculate creatinine clearance, an estimate of kidney filtering, and to express other substances in the same collection relative to creatinine. Higher or lower amounts mainly reflect muscle mass, diet such as meat intake, and collection accuracy, so it is interpreted alongside the other results it accompanies.
Tests that include Creatinine, 24 Hour
This test measures the amount of creatinine expelled in the urine over a 24-hour period and is used to evaluate kidney function. This test helps determine how well the kidneys are able to filter small molecules like creatinine out of the blood. It is often used in conjunction with blood creatinine tests to calculate the creatinine clearance rate, which can provide more detailed information on kidney filtration efficiency. This is particularly useful in detecting renal dysfunction and monitoring known kidney disease or conditions affecting kidney performance.
- Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
Urine chloride excretion approximates the dietary intake. The chloride content of most foods parallels that of sodium. An increase in urine chloride may result from water-deficient dehydration, diabetic acidosis, Addison's Disease, and salt-losing renal disease. Decreased urine levels are seen in congestive heart failure, severe diaphoresis, and in hypochloremic metabolic alkalosis due to prolonged vomiting.
- Chloride, 24 Hour Measures the total chloride passed in your urine over 24 hours, helping assess salt and fluid balance and causes of abnormal blood electrolytes.
- Chloride/Creatinine Ratio A calculated ratio of chloride to creatinine in your 24-hour urine, used to put urinary chloride in context of urine concentration and collection.
- Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
This test is an aid to evaluate patients suspected of having systemic mastocytosis using 24-hour urine collections.
- Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
- Leukotriene E4, 24 Hour Measures leukotriene E4 in a 24-hour urine collection, a marker of inflammatory leukotriene production used mainly to help evaluate mast cell disorders.
Phosphorus is present in many foods, with a mean intake of approximately 1500 mg per day for adult males and about 1000 mg per day for adult females. Absorbed phosphate, under the influence of parathyroid hormone, is readily excreted in the kidney. Measurement of urinary phosphorus generally reflects dietary intake; hence, day-to-day excretion may show considerable variation.
- Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
- Phosphate, 24 Hour Measures the total phosphate your kidneys excrete in urine over 24 hours, helping assess phosphate balance, kidney handling and kidney stone risk.
- Phosphate/Creatinine Ratio A ratio calculated from urine phosphate and urine creatinine, used to judge phosphate excretion while adjusting for how concentrated the urine is.
This test is crucial for evaluating hydration status and the overall balance of electrolytes in the body. It involves analyzing a 24-hour collection of urine to measure potassium levels, which play a key role in nerve function, muscle control, and heart health.
- Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
- Potassium, 24-Hour Measures the total potassium your kidneys excrete in urine over 24 hours, helping explain abnormal blood potassium and assess kidney handling of it.
- Potassium/Creatinine Ratio A ratio calculated from urine potassium and urine creatinine, used to judge potassium excretion while adjusting for how concentrated the urine is.
Urinary total proteins are negligible in healthy individuals. Concentrations are increased in patients with a wide variety of diseases that impair renal function, including diabetes, hypertension, nephritic syndrome, and drug nephrotoxicity.
- Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
- Protein/Creatinine Ratio, 24 Hr A ratio calculated from protein and creatinine in a 24-hour urine collection, used to assess how much protein your kidneys are leaking.
- Protein, Total, 24 Hr Measures the total protein passed in your urine over 24 hours, used to quantify and monitor protein loss through the kidneys.
Urine uric acid may supplement serum uric acid testing when trying to identify conditions in which there is alteration of uric acid production or excretion, e.g., gout, leukemia, renal disease. The amount of uric acid excreted may be useful in treating asymptomatic hyperuricemia. Measurement of urine uric acid is important in the investigation of urolithiasis.
- Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
- Uric Acid, 24 Hour Measures the total uric acid you pass in urine over 24 hours, used to look into kidney stones and how your body handles uric acid.
- Uric Acid/Creatinine Ratio, 24 Hour A ratio calculated from uric acid and creatinine in the same 24-hour urine collection, used to put uric acid excretion in context.
