Normal ranges?

[Lynn63]

Can someone list or direct me to a list of the new normal ranges for relevant bloodwork for thyroid?  I had left lobe of thyroid removed a few months ago and am hypo.  I am on synthroid but ENT who did surgery ran TSH only and nurse called to say that I am still a little low on TSH but he doesn't want to adjust my medicine.  I plan to go to my internal medicine doctor (who told me she could take over hypo treatment once the ENT had gotten dose level).  I plan to ask her to run the appropriate bloodwork but would like to know normal levels/what should be checked.

thanks!

Thank you so much.....I will be sure to get copies of labs so I can use the tracker to keep up with it.

In my opinion the best approach for treatment of hypothyroidism is to pay close attention to the patient's symptoms and test for free T3 and free T4 (not total free T3 and T4) and prescribe meds as required to adjust those levels to best alleviate the symptoms.   The reasoning behind this is that free T3 is the most active component of thyroid hormone.  It is 4 times as potent as T4 and largely regulates metabolism.  Testing for free T3 and free T4 is more important than testing for TSH, although TSH seems still to be the predominant test used by doctors. In reality,  the labs and doctors can't even get agreement on what reference range to use for TSH.   The old range was typically .5-5.0.  The AACE recommended changing to .3-3.0 about 5 years ago, but still not used by very many labs/doctors.

Many patients report that they feel best when their free T3 is in the upper part of its
range.  The reference range for free T3 depends on the lab and the measurement units.  For example I've seen 1.6-4.2 pg/ml, as well as  230-619 pg/dl.  Don't worry about those, the lab report will show the reference range.  Just make sure you always get a copy of the lab results, for reference.
