Chest pain may be caused by poor blood flow to the heart leading to angina, or by a sudden blockage in the coronary arteries resulting in a heart attack. Other causes of chest pain can include indigestion, reflux, muscle strain, inflammation in the rib joints near the breastbone, and herpes zoster or shingles.
Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment. If your GFR number is low, your kidneys are not working as well as they should.
An eGFR blood test maybe recommended by your doctor to determine the creatinine levels in the blood. The test reveals kidney function and indicates how well or poorly your kidneys are filtering the creatinine (waste produced through muscle function) from your blood. EGFR stands for estimated glomerular filtration rate.
