i am due to have an MRI scan in a few weeks time so the hospital sent me a letter with my appointment details saying they want me to have a ESTIMATED GLOMERULAR FILTRATION RATE TEST to see how well my kidneys are functioning as there is possibility they will use an intravenous injection of a colourless dye known as MRI gadolinium contrast.
So i saw my GP todays requesting this test but now im home and have seen the blood test request form (which i take with me to get my blood drawn) the test requested is a UREA + ELECTROLYTES SERUM
So im now worried hes requesting the wrong test,
So does anyone know if a UREA + ELECTROLYTES SERUM TEST is the same/finds out how well my kidneys are working?
his next free appointment is too late to clarify this
