There is more than one assay method, and each has a different normal range, based on your age. Your results may indicate the range and method used.

That's only a difference of 16% between the two values.

If you think that each assay has an accuracy of (say) 10% then you can see that the values are quite similar.

The average of these two values is 304.

Also as rrxing has rightly said in the previous post, each assay method has a different range. You cannot directly compare the values tested in two methods.

Thank you very much indeed Trys and rrxing.

The normal range you'll need to find from the place you had it tested.

For somebody between the age of 40-54 years (Male or Female), then according to my big orange book (Greenspan 'Basic & Clinical Endocrinology'), the normal range is 90-360 ug/L.

Hopefully, that's good news for you?
