An EGFR blood test (Epidermal Growth Factor Receptor blood test) is designed to screen for and detect problems with the kidneys, and is additionally used to monitor the status of your kidneys if you are being treated for kidney ailments. If your physician wishes to evaluate the condition of your kidneys, he or she will recommend that you have an EGFR blood test blood test or creatinine test when you have your blood urine nitrogen and comprehensive metabolic panel. This helps in monitoring your kidneys’ condition, or, if you are diabetic or have high blood pressure, in determining what the reason is for harm to your kidneys.
Your EGFR blood test is able to help in measuring creatinine levels, without the need for additional testing. The test can be run on a routine basis, whenever your creatinine tests are conducted. Your physician may order the test when he or she wishes to evaluate your kidney function at routine check-ups or when there is a chance that there are problems in the kidneys.
Some indicators of possible kidney damage or disease include urine that is coffee-colored or blood-speckled, times when you have swollen areas around your ankles, thighs, stomach or facial areas, or when you have a lowered rate of urination. Your physician may also recommend an EGFR blood test if you have irregular emissions when you urinate, or a burning sensation upon urination. You may also experience pain in your lower middle back, or hypertension.
An EGFR test can be done at regular intervals, if you have a kidney problem, high blood pressure or diabetes. It can reliably detect the condition of your kidneys even in early stages, when compared with a creatinine test alone. Since the computation at the laboratory will work best for assessing the reasons for lower renal functioning, there are specific levels or normal ranges to be checked.
If the results of your EGFR blood test are lower than normal, this may indicate kidney damage. The EGFR testing and outcomes will determine whether you will need to have ongoing testing done. If your conditions worsen, including less or more common urination, a loss of appetite or nausea, this may indicate that the creatinine levels need to be rechecked.
