Question 1

t4 free 1.8
t3 free 4.3
1.8 borderline 
4.3 little high
what is going on? can this be transient?

Accepted Answer

Need labs normals: without an exam, I can only give general information, but lab values are derived from averages of a bunch of people. Being very close to the values of average generally means you are not abnormal.
and... can see if the values get worse over time (implies a hormone secreting growth (not cancer) that is growing more abnormal). Or.. its' normal next time.

Question 2

tsh 0.01 normal is 0.40>
t3 free is is 4.3 normal is 2.3-4.2 
t4 free 1.8 normal is 0.8 to 1.8 
is this dangerous ? life threatening ? help please

Accepted Answer

Hyperthyroid: Hi. You're hyperthyroid. At your stated age of 26, it's not life threatening, but my advice is always to treat it. As you can see from the numbers, yours is fairly mild (we see hyperthyroidism a lot more extreme), but it still places you at risk for an accelerated heart rate and irregular rhythm, and feely not-so-well in many ways. It could be one of several conditions. See an endocrinologist.

Question 3

2nd tsh of 2.45 after initial result of 3.96 21 days ago. tested at different time of day.t3 free at 2.7 and t4 free 1.17. antibodies test is negative.severe hypo symptoms are present.                                              should i be concerned? ar

Accepted Answer

Thyroid tests: Allthe test you have listed with the results.Tsh, free t3and T4 are all normal, you do not have hypothyroidism and should consult your doctor as to what is causing your symptoms.

Question 4

been on levothyroxine 1 yr 3 months. no period at 18 yrs old and distance runner. worked with nutritionist and gained 10 lbs but no period. possibly still undereating but wondered if i ate more my t3 free levels would improve. would i gain weight?

Accepted Answer

Hypothyroidism: I commend you for gaining 10lbs
Hypothyroidism can cause depression affecting your” period”
“It is NOT what you eat-
It Is WHAT is eating You!
At age of 18, you possibly are going through stresses of relationships, separation, school and finances causing depression.
See Endocrinologist for Thyroid problem, blood test for T3, T4 and TSH and dose of Levothyroxine
and Psychiatrist for depression.

Question 5

is it possible to fix low thyroid (t3 free) without gaining weight? mine has been low for over a year because of underfueling while i exercise a lot as a college runner. dont want to gain weight, as i already gained 10 lbs but i want thyroid fixed?

Accepted Answer

Hypothyroid: If your thyroid level is low free t3 or T4, then you should be on medications that can actually help with losing weight instead of gaining. Untreated low thyroid can cause weight gain.

Question 6

tsh=0.01 miu/l range 0.4-4.5 l
t4,free=3.1 ng/dl range 0.8-18 
t3,free =7.2 pg/ml range 2.3-4.2 
mild ,moderately severe or severe hyperthyroidism ?

Accepted Answer

It depends: On the paper it looks like your free t3 close to the double the amount of normal range of free t3. So it needs to be  reduced to the 4.2 pg/ml . In order to do that i think your prescriber  should decrease the dosage of the daily thyroid hormone supplement to you. You prescriber also to take into account your symptoms while trying to bring down your free t3 level.

Question 7

are these thyroid levels normal? dr insists they are, but i feel awful & have a family history.

tsh 1.40 uiu/ml
t4 free 1.06 ng/dl
t3 free 2.9 pg/ml

Accepted Answer

Normal results: 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, your laboratory results for thyroid function are normal. There may be other causes for your symptoms, including depression.
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. 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.

Question 8

normal free t3/free t4. elevated tsh (5.50). hypothyroidism??

Accepted Answer

Yes or No: No, if the patient has no symptoms and is a normal person with a normal thyroid gland. Yes, if the person's thyroid gland is actually working overtime to maintain adequate levels of thyroid hormones. The question is not merely what to call it, but more about whether or not the thyroid gland is working overtime and whether or not to supplement with thyroid pills to let the thyroid gland rest a bit.

Question 9

tsh normal range (1.26) 
t4 free normal range (1.22)
t3 free low normal range (2.5)
t3 uptake low (23)
thyroglobulin antibody high (1.1)

Accepted Answer

More info needed: A screening test or on thyroid med?  He has a normal TSH and normal free T4, so he is normal or has normal replacement results. The T-3 uptake is irrelevant. Many normal individuals have anti-thyroid antibodies. If his thyroid isn't enlarged or has no nodules, don't worry about it. If you are still concerned ask for a referral to an endocrinologist.

Question 10

current tsh w/reflex to ft4 0.13, t4 free 1.3. t3 free 2.7. on levrothyroxine. taken off lyrothyronine in jan. osteoporosis. gained 9 lbs &  fatigued?

Accepted Answer

Hypothyroidism: Your thyroid panel results may need to be repeated as you have now off medication for a while and some of your symptoms may be due to the hypothyroidism. Please see your PCP or endocrinologist to discuss further evaluation and treatment options. Feel better soon!
