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.
eGFR-stands for estimated Glomerular Filtration Rate, which is a. derived value from serum creatinine, age, sex, and race. It is an estimate of kidney function. The laboratory eGFR is not corrected for race currently.(x1.21 if Afro-caribbean) The 95% confidence intervals for the eGFR values are quite large (about +/- 30%) e.g. eGFR for a 60 yr old male with creatinine of 150 would be 44 (95% confidence limits 31 to 57).he laboratory eGFR is not corrected for race currently.
