Hi bleauberry
I went to the manufacturers of the assaying equipment to get some indication of the mean average thyroid activity...
"Expected Values
It is recommended that each laboratory establish its own reference intervals. The expected values presented here are based on testing of apparently healthy blood donors. Samples were measured in duplicates unseeing different kit lots.
In a population (n = 243) of adult female blood donors (ages: mean 37.8 ± 11.3, range 19 - 69) serum concentrations of FT4 were 14.26 ± 1.91 pmol/l (mean ± SD). Sample values were found scattered in a range of 10.1 22 pmol/l.
In a population (n = 243) of adult male blood donors (ages: mean 29.0 ± 10.5 range 19 - 61) serum concentrations of FT4 were 15.4 ± 2.32 pmol/l (mean ± SD). Sample values were found scattered in a range of 10.1 22.5 pmol/l.
For female and male (n = 486, ages: mean 33.4 ± 11.7, range 19 - 69) the serum concentration of FT4 was 14.83 ± 2.2 pmol/l (mean ± SD), range 10.1 22.5 pmol/l.
As a guide (mean ± 2*SD), 10.4 19.2 pmol/l reference range was obtained from normal patients based on statistical consideration only. Taking into consideration not only statistical results but clinical practice as well more realistic reference range of 10-22 pmol/l can be recommended."

Expected value for FT4 for a healthy person is 15.4 to 15.6 pmol/L. I suspect that the real value we want to look at is the T3.
