What the FT4 Can and Cannot Tell You in Sandy
A normal-looking FT4 result does not rule out every possibility, just as an abnormal one is not a diagnosis. The FT4 is most useful when its results are interpreted together with your overall health picture. For questions the FT4 cannot answer, a provider may recommend other tests or an evaluation. The FT4 can show how the markers it measures compare to the laboratory's reference range.
High and Low FT4 Results
Reference ranges for the FT4 are printed on the report, and results should be read against that range. If a FT4 value is outside the range, a provider can explain the possible reasons and the next steps. The FT4 report shows whether each value sits above, below, or within the reference range. A value above the range is called high and one below is called low, but either can have many explanations.
