I think everything should be mentioned to your doctors as it may help complete the puzzle. Definitely let them know about the test results.
Low iron can cause weakness.
There are lots of things that can cause iron-deficiency anemia - which it sounds like you may have. What are the next steps for you? Have they mentioned any scope testing?
"blood smear panel test showed RBC Morphology abnormal, should this be mentioned to doctors..." ?
It is a big clue. They'll need to know the actual type of misshapen RBCs - and the number of them can be important, too. So they'll want to see the report, or redo the smear.
But the ER doc didn't care? Well then, maybe because the number was too small to be significant.
"Other morphologic abnormalities are significant only when seen in considerable numbers. These include:
Burr cells (echinocytes)
Hypochromic cells "
...and if the scope doesn't find bleeding or malabsorption, then the smear becomes more important.
Hello~I would take all the test info and any other info you have to your regular GP; discuss your concerns over the results of the blood tests and any symptoms you may have. He/she will hopefully be able to put your mind at ease.
I think the whole thing should be mentioned to your doctors as it may support complete the problem. Absolutely let them know about the test Report.
