| Re: formula for thyroid bloodwork?
Assumption
FT4 1.0 Range (0.8-1.8)
Percentage calculation: [Your value - lower range limit]/[upper range limit - lower range limit]*100 = %
[1.0-.8]/[1.8-.8]*100 = 20%
FT3 is done the same way: 260 (230 - 4 2 0)
[260-230]/[420-230]*100 = 15.79%
Other thing to note is balance. If your Fts are not with in 10 % of each other then something is off in you conversion process, adrenal T3 conversion suppression, or pituitary request for T4 to t3 conversion and further testing is necessary.
Good luck. Keep a flow chart of your labs and a daily symptom log with heart rate, BP, and temperature values. This can help more than you know when trying to track down rhythms of thyroid flux.
