My TSH W/REFLEX TO FT4 result is 0.67. I am 52 and female. What does this mean?

Normal: That's a normal value. That's why they didn't have to run the free t4. Reflex means they will run ft4 only if tsh is abnormal. ...Read more

Is TSH w/reflex to ft4 4.06 normal?

Is TSH w/reflex to ft4 4.06 normal?

High normal: A TSH of 4.06 is in the upper range of normal. The lab probably did not do the ft4 level, since the TSH was normal. Most people with these results feel perfectly normal. However, it could be a sign that your thyroid is starting to fail. It would be reasonable to repeat the TSH and do a free T4 level in a few months. ...Read more

My TSH w/reflex to ft4 results are 15.44. What does this mean?

HYPOTHRYOID: Your thyroid gland is underactive it is not producing enough thyroxine.

I'm on Levothyroxine and Cytomel for T3 and T4 and my blood work came back TSH w/Reflex to FT4 is 0.01 L and T4, FREE is 0.6 L. What does this mean?

I'm on Levothyroxine and Cytomel for T3 and T4 and my blood work came back TSH w/Reflex to FT4 is 0.01 L and T4, FREE is 0.6 L.  What does this mean?

Several things: Hi. Without seeing your thyroid function over time, I'd say the fact that you have a goiter & 2 cm nodule (same thing, or different?) AND taking T4 AND T3, you may be over-treated with T3 so that your TSH is suppressed and that causes low free T4, which is not made up for by the levothyroxine you're taking. I suggest you talk with your doctor, who won't have to guess like we do! Good luck! ...Read more

I meet all the symptoms for hypothyroidism: sparse eyebrows, fatigue, dry skin, I have ibs, cmp TSH w/reflex to ft4 is 4.44, yet dr said i don't. Do i?

Hypothyroidism: Hi, you may have subclinical hypothyroidism, and/ or hashimoto's thyroiditis. You may need to have further testing done, thyroid auto-antibodies, anti-per -oxidase antibodies lab tests and perhaps a thyroid sonar. It may be a good idea to see an endocrinologist, literature shows that thyroid hormone replacement may benefit you. Good luck! ...Read more

What does "Tsh with reflex(reflux?) to FT4" mean with blood work?Does that mean it's as complete thyroid check?

No: TSH (Thyroid Stimulating Hormone) is a marker for thyroid function. If it is abnormally high, the lab automatically (reflexively) does a Free T4 level. This is useful for diagnosing hypothyroidism, but it is not the same as a full thyroid panel. Hope this helps! ...Read more

Within normal limits: Your free T4 level is within normal limits. The symptoms you described do not lend to providing a meaningful opinion without more history, physical examination and the lab data. It would be prudent to discuss the matter with your doctor. ...Read more
