Blood creatinine levels are checked to assess kidney function. Creatinine is a waste product in your blood that comes from normal muscle wear and tear. The kidneys are responsible for the removal of creatinine from the blood, so if your kidney function declines, creatinine levels in the blood r...
is another test that is used to assess kidney function. This test measures how well the kidneys filter out creatinine over a given period. Instead of a blood sample, creatinine clearance is usually determined from a measurement of creatinine in a 24-hour urine sample and from a blood sample ...
Low blood creatinine levels are not always a concern. They can just indicate a diet low in protein [43]. Your doctor will interpret your results, taking into account your medical history, symptoms, and other test results. Causes of Low Creatinine Causes listed below are commonly associated with...
Over-fasting also might result in hypoglycemia— a condition in which the blood glucose becomes too low to provide the energy needed to do an activity. People taking the test, therefore, should avoid over-fasting to prevent delay in the test. Doctors urge each person to have an annual check...
People over age 60 may have an apparently normal creatinine blood level but still have a low GFR. The opposite can also be true, where the person may have a mildly low GFR without having kidney disease. The 24-hour urine collection method or another blood test called cystatin C can more ...
Creatinine blood test:A test that helps determine whether the kidneys are functioning normally. The kidneys maintain the blood creatinine in anormal range. Creatinine has been found to be a fairly reliable indicator of kidney function. As the kidneys become impaired for any reason, the creatinine ...
Creatinine levels are determined with a blood test and lab analysis. Lab technicians will usually provide normal range references with lab results so that the results can be read and interpreted easily. If a doctor notes that creatinine levels are low, the patient's chart will be consulted for...
Creatinine levels are measured through blood samples. Kidney damage can be a result of many medical problems, some of which can be life threatening. Infections, cancer, and being in a state of shock can all cause high creatinine levels. Other less severe conditions that elevate creatinine include...
2.3.1 Blood/serum Blood or serum is one of the most widely used diagnostic fluids for clinical analysis of creatinine. In fact, creatinine detection is generally included in a typical blood test as a measure to assess renal functions. Serum based creatinine detection is traditionally based on th...
A high BUN/creatinine ratio in your blood tests may result from three reasons: elevated BUN and normal creatinine, normal BUN and low creatinine, or both BUN and creatinine elevated, but BUN is disproportionately higher. On the other hand, BUN creatinine ratio blood test low results may be be...
