"Is the T4 and Total T4 the same test?"
No, they are not the same, Total T4 measures the total amount of T4 in your blood, most of it is bounded to protein and can not be used by your body, this is why you should look at the FREE T4!
"When I google'd ref range for T4 all I could find was Total T4 range is 5.0 to 12.0, so can I assume the T4 results are low?"
Reference range change from lab to lab different labs use different reference range, in your case it is for Total T4 and thus not important, you need to look at the free t4 reference range!
"My symptoms are severe fatigue & muscle pain, heart palps & shakiness, bad acid reflux, insomnia, anxiety, exercise intolerance, hair loss of over 50%, and more but those are the worse symptoms."
