Question 1

Tsh w\reflex to free t4 is .22.   free t4 is 1.65 is this normal.
i take 75 synthroid?

Accepted Answer

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, free T4 value is normal. The low TSH suggests need for a discussion with your doctor about reducing the dose of synthroid.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. 
Practice safe sex, if you have sex. 
Get HPV vaccine, if you are under 27 years of age.

Question 2

My tsh with reflex to t4 came back at 0.623 mclu/ml. my free t4 came back at 2.1 ng/dl. is this normal?

Accepted Answer

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, the information you provided is in the normal range.    Wish you good health!

Question 3

I had a tsh reflex to free t4 blood test done, my result is 3.70 (0.40-4.50 miu/l), is this normal?   thank you.

Accepted Answer

That appears to be within the normal range, based on the laboratory standard you provided.

Question 4

Tsh reflex free t4 test = 2.51 (normal range 0.35-4.50).  i've read hyperthyroidism still possible if tsh normal.  do i need another test?

Accepted Answer

Highly unlikely.
That said, your doctor should have ordered TSH and T3 (liothyronine) as well as T4. Please go back to him/her or if you are not satisfied have a friend or family refer you to a better doctor.

Question 5

My tsh with reflex to free t4 and t3 (liothyronine) came out to a range of 1.0 . is that normal ? been feeling horrific since i gave birth 5 months ago .

Accepted Answer

Hi. That's a normal TSH, but testing TSH alone only tests dysfunction of the thyroid gland itself. You need to get a TSH AND a free T4 (i.e., NOT "reflex") to see pituitary hypothyroidism (which, btw, can occur in rare cases associated with a particularly bloody delivery). Of course many problems can make you feel horrific. Can you make milk? I don't know what is wrong, but you need further eval.

Question 6

Tsh reflex free t4 result 0.76 what does this mean?

Accepted Answer

Lab values can vary (even if there has been no change in a patient's status nor medications). That is why lab results are "just numbers," and one should see her doctor (who knows the whole story) for an interpretation of her results. A "reflex" test is done usually if the first test is outside the reference range. Thus, if TSH is above or below the reference range, a Free T4 hormone test is done.

Question 7

My t4 free is 0.70 and my tsh reflex free t4 is 29.2. what does this mean and what do i need to do?

Accepted Answer

This is diagnostic of hypothyroidism and should be treated with thyroid hormone replacement which hopefully was done by the doctor who got these labs. While without a little more history is there is the remote chance of thyroiditis, it is unlikely with a TSH in this range. While EASILY TREATABLE, hypothyroidism can be a serious and even eventually a life threatening disease.

Question 8

My tsh is 9 & my tsh reflex to free t4 is 1.29 & i still don't feel well! should my levothyroxine 75 mcg be increased?

Accepted Answer

Please have your doctor repeat your thyroid levels -

TSH, Free T4, Free T3 (liothyronine).

Question 9

Blood test tsh reflex to free t4 = 5.700 vit b12= 1260 is this serious?

Accepted Answer

B12 is not serious. If your TSH is 5.7, you have thyroid deficiency, if your free T4 is 5.7 you have hyperthyroidism. All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. 
Wish you good health!

Question 10

My tsh w/reflex to ft4 test came back at 6.73, but my free t4 came back at 1.24.  i have previous has similar results to these tests.

Accepted Answer

The elevated TSH means that your pituitary gland is not happy with your thyroid level, and would like to see it higher despite the "normal" free T4 level. If you do not have any symptoms of hypothyroidism, we call this "subclinical hypothyroidism". Treatment may not be needed unless you develop symptoms or the TSH goes progressively higher. You should not start treatment based on one abnormal test
