Hi,
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

Have you tried calling them? The doctor's nurse should be able to answer your questions over the phone. You could also try calling the facility that will be doing the MRI to make certain that it's the correct test.
