TT4 Rapid Quantitative Test

Product Specification

Clinical Significance

✔ Abnormally high test results
Elevated TT4 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:

1. High levels of protein in the blood

2. Too much iodine

3. Too much thyroid replacement medication

4. Trophoblastic disease, a group of rare pregnancy-related tumors

5. Germ cell tumors

6. Too much iodine can raise your TT4 levels. Because X-ray dyes can include iodine, a recent X-ray involving dye may also raise your TT4 test results

Abnormally low levels of TT4 may indicate:

1. Dietary issues, such as fasting, malnutrition, or an iodine deficiency

2. Medications that affect protein levels

3. Hypothyroidism

4. Illness

5. A pituitary problem

Intent Use
