No you cannot. After suffering from low thyroid for over 15 years which my doctor never caught despite annual thyroid tests I researched it on my own. I might also add I was taking levothyroxine the entire time after having a thyroidectomy. Not once did a doctor even inform me that a thyroid panel existed much less suggest one in spite of my constant reporting of low thyroid symptoms. I am currently off the levothyroxine after beginning iodine supplements. My question is for Dr. Shehzad Topiwala is WHY DO YOU HOLD YOURSELF UP TO THE WORLD AS AN EXPERT ON THE SUBJECT AND LIE TO PEOPLE WHILE YOU CHARGE THEM TO DO SO? Medicine needs a good kick in the rear to insert some ethics in to it. Have a better day tomorrow.
