The normal range: it is not normal and it is not a range

Abstract

The NHS ‘Choose Wisely’ campaign places greater emphasis on the clinician-patient dialogue. Patients are often in receipt of their laboratory data and want to know whether they are normal. But what is meant by normal? Comparator data, to a measured value, are colloquially known as the ‘normal range’. It is often assumed that a result outside this limit signals disease and a result within health. However, this range is correctly termed the ‘reference interval’. The clinical risk from a measured value is continuous, not binary. The reference interval provides a point of reference against which to interpret an individual’s results—rather than defining normality itself. This article discusses the theory of normality—and describes that it is relative and situational. The concept of normality being not an absolute state influenced the development of the reference interval. We conclude with suggestions to optimise the use and interpretation of the reference interval, thereby facilitating greater patient understanding.

It would be helpful to give reference ranges for your results so that they can be interpreted accurately, but from all the ranges we see here it seems that your results would be considered euthyroid (normal). If your FT4 was at the very bottom of the range or below range then that would be of concern but at 14.7 it doesn't come at the bottom of any range we see here.

It would be a good idea to test key nutrients

as low levels or deficiencies bring their own symptoms, and iron deficiency can mirror or coincide with those in thyroid disease.
