Clinical Significance
✔ Abnormally high test results
Elevated T4 levels may indicate hyperthyroidism. They may also indicate other thyroid problems, such as thyroiditis or toxic multinodular goiter
Other reasons for abnormal results may include:
high levels of protein in the blood
Too much iodine can raise your T4 levels. Because X-ray dyes can include iodine, a recent X-ray involving dye may also raise your T4 test results
Intent Use
A T4 test is used to evaluate thyroid function and diagnose thyroid disease.
