What is creatinine clearance?
Clearation Creatinine test concerns blood and urine tests that are used to assess the kidney function. If the physician finds that the patient may have the abnormality of kidney function, such as kidney failure or renal obstruction, the clearance test can recommend. This diagnostic medical test requires both a blood sample and a urine sample. The laboratory compares creatinine levels in both samples to calculate the speed of clearance. When calculating the test results, the patient's height and weight are usually taken into account. Usually creatinine is removed by the kidneys, so the elevated level of this waste product in the bloodstream is less than optimal kidney filtration. In general, creatinine clearance testing is measuring creatinine levels and blood that has been produced in the last period of 24 hours. These results are used to determine creatininukter levels have been cleaned from the blood and filtered into the urine.
symptoms, which may alert the doctor to order a creatinine clearance test, include swelling of the face, abdomen or limbs. In addition, reduced levels of urine output are important and bloody, dark or foam urine, which can be guaranteed by the clearance test. Sometimes side or medium back and presence of high blood pressure or protein in the urine may be alerted to order a creatinine clearance test. Usually there is no special preparation for the patient's test.
In general, diseases or conditions that disrupt the kidney's ability to clean waste products from the blood, bring increased creatinine levels in the blood. In addition, creatinine clearance can be reduced because the reduced amount of creatinine is excreted in the urine. Former, reduced creatinine clearance values may indicate congestive heart failure, acute kidney failure or kidney tumor. Increased values may occasionally indicate pregnancy or may be the result of energetic exercise.
Sometimes if the PatieNT consumes high protein or meat diet, the test will be increased and repetition. In addition, certain medicines can change the test. Medicines called diuretics can provide false positive reading. Diuretic drugs are also known as water pills. These drugs promote frequent urination and are indicated in the treatment of hypertension or high blood pressure. Other drugs that can distort the test results are stomach acid reducers and certain antibiotics.
