Meavis, can you post the units in which your rT3 was measured please. I have tried to reverse engineer your .33 to see if I can guess at your units - but it's after midnight here and I am beginning to fade. I can work it out for you but to get it right I need the units. In the US it is in ng/dL but those are not your units.
This calculation is a nightmare of units because they measure the two quantities in different units - well in the US they do - so then you have to get both quantities in the same units. Anyway, pls post units.
