The result is how far TSH sits outside 0.4-4.0 mIU/L (0 when inside the range). When the field is empty, there is no main result. Weight-change kilograms sit beside that gap. In the first example the result is 0.0 mIU/L.
The calculator does not diagnose thyroid disease and does not choose levothyroxine. The result is how far TSH sits outside 0.4-4.0 mIU/L (0 when inside the range). When the field is empty, there is no main result. Weight-change kilograms sit beside that gap.
Enter data and click Calculate.
The calculator uses the numbers you enter. The result is how far TSH sits outside 0.4-4.0 mIU/L (0 when inside the range). When the field is empty, there is no main result. Weight-change kilograms sit beside that gap. In the first example the result is 0.0 mIU/L.
The five form fields are Palpitations / tremor, Fatigue / hypersomnia, 6-month weight change magnitude, TSH if known, and Family autoimmune thyroid disease. TSH deviation means: This is the main result on this page. In the first example it is 0.0 mIU/L. Palpitations / tremor means: The first form field. It enters the formula or sits beside the result. The result is how far TSH sits outside 0.4-4.0 mIU/L (0 when inside the range). When the field is empty, there is no main result. Weight-change kilograms sit beside that gap. Fatigue / hypersomnia means: The second form field. The calculator does not diagnose thyroid disease and does not choose levothyroxine.
The second example gives +2.8 mIU/L. The third example gives 0.0 mIU/L. The result is how far TSH sits outside 0.4-4.0 mIU/L (0 when inside the range). When the field is empty, there is no main result. Weight-change kilograms sit beside that gap. In the first example the result is 0.0 mIU/L.
The calculator does not diagnose thyroid disease and does not choose levothyroxine.
Enter 3, 4, 2, 2.1, 0, then click Calculate. A comma in 12.5 is read the same way as a period. Fields on a 0-10 scale are notes and are not the primary result unless this page formula says so.

With the second set of fields the result is +2.8 mIU/L.
With the third set of fields the result is 0.0 mIU/L.
The result is how far TSH sits outside 0.4-4.0 mIU/L (0 when inside the range). When the field is empty, there is no main result. Weight-change kilograms sit beside that gap.
The calculator does not diagnose thyroid disease and does not choose levothyroxine.
This is the main result on this page. In the first example it is 0.0 mIU/L. The first form field. It enters the formula or sits beside the result. The result is how far TSH sits outside 0.4-4.0 mIU/L (0 when inside the range). When the field is empty, there is no main result. Weight-change kilograms sit beside that gap. The second form field. The calculator does not diagnose thyroid disease and does not choose levothyroxine.
Yes. 12.5 and 12,5 are read the same way.
No. Fields on a 0-10 scale are notes, unless this page formula counts marked items from them. The primary result comes from this page formula.
From the 0.4-4.0 mIU/L range. Inside the range the result is 0. Above 4.0 or below 0.4 you see the gap. An empty field means no main result, not a fake 5.
No. The calculator does not choose levothyroxine and does not replace FT4.
They sit beside the TSH gap. They do not move the 0.4-4.0 range.
An empty field leaves no result. Typing 5 fakes a measurement and breaks the deviation.
