Christopher Ellis explains why TSH alone misses thyroid problems and serum iron alone misses iron deficiency. A full thyroid panel and iron panel with ferritin give you the actual picture of what's happening in your body.
Full thyroid panel. Oftentimes just TSH is looked at. I think a full thyroid panel is very important. A full iron panel. Just testing iron alone is not enough. Only 1% of the iron in your body floats around in the blood serum. So, it's not the best marker for— iron is not the best marker for testing iron. Actually, ferritin, which is where your body stores iron, that's a much better indicator of iron status.
