Frequently Asked Questions (FAQ's):
1. What does the Total T4 test measure?
It measures the total amount of thyroxine (T4), including both hormone bound to proteins and the free, active form circulating in your blood.
2. Why is the Total T4 test important for thyroid health?
It helps identify whether your thyroid is producing too much or too little hormone, which is essential in diagnosing hyperthyroidism or hypothyroidism.
3. How is Total T4 different from Free T4?
Total T4 includes both bound and unbound hormone, while Free T4 specifically measures the unbound, biologically available form.
4. Do I need to fast before the T4 test?
No, fasting is usually not required. You can take the test at any time unless otherwise advised by your healthcare provider.
5. What can affect Total T4 levels?
Factors such as pregnancy, illness, certain medications, or variations in thyroid-binding proteins can influence T4 results.
6. How are Total T4 results interpreted?
High T4 levels may indicate an overactive thyroid, while low levels suggest an underactive thyroid or secondary hormonal imbalance. Results are interpreted in conjunction with TSH and T3 tests.
