Low T4 And High Tsh Levels
Hypothyroidism: The TSH test is10 times more sensitive for the diagnosis of hypothyroidism that the t4. The TSH is reported on a log scale so that small changes in the TSH value are caused by relatively big changes in the blood level. This is a reflection of the pituitary being extremely sensitive to change in the T3 (liothyronine) level if you have symptoms it would be wise to seek treatment. ...Read more
Subclinical hypothyr: Hi. That is commonly seen, now that we screen so well for disorders of thyroid function. It's called subclinical hypothyroidism, meaning that with extra push from the pituitary (TSH), the remaining thyroid tissue is able to make thyroid hormone in the normal range. You should start taking thyroid hormone now, and not wait till your metabolic tank is empty. Good luck! ...Read more
Yes: Hypothyroidism can be primary - caused by a weak thyroid gland or secondary to other hormonal problems, like a pituitary problem. Or your thyroid can become dysfunctional secondary to high insulin, estrogen or cortisol. If you have functional hypothyroidism, this problem can go undetected by routine screening tests. More extensive testing can often reveal abonormalities. This is very common. ...Read more
Pheochromocytoma could it be detremined by the TSH and the free T4 ? And if it can should they be low or high? Tsh is 0.6 and the free T4 is 3.2
HiTSH=hypo,hiT4 hype: Thyroid function is measured many ways. The TSH is your body's call for more hormone, so a high TSH suggests underactive thyroid, very low TSH overactive. The t4/t3 levels are measures of circulating hormone, so high T4 or T3 (liothyronine) suggest hyperthyroidism and vice versa. T4 levels can beaffected by hormones and so need to be interpreted carefully. For initial testing, the TSH alone best test. ...Read more
Can you still be hypo after having high TSH -6.97 months back and now 5.9- neg antibodies? Thyroid US done which was fine. T4 low normal range.
High TSH, low thyro: Your pituitary gland tells you that you are not having enough thyroid by producing more TSH. Thus whenever it is high, it means you need more thyroid. ...Read more
Im 42 type2 diabates for 10 yrs (avg 180 sugar level), recent lab test shows high tsh:11.5 (range 0.3-4.2) but normal free t4: 19 (ref12-22), vit d 11.3
Lab error?: The TSH is elevated, but the free T4 is in the upper range of normal. One can have subclinical hypothyroidism where the TSH level is high, with normal free t4, though usually the free T4 is in the low range of normal. You should have the test repeated after 1 month. Your vitamin d level looks low, you should take a vit d supplement of around 2000 iu daily. ...Read more
My thyroid panel shows low T3 (liothyronine) (29), normal T4 (8.10) and high TSH 3.16. What does this mean
TSH normal: Your TSH is normal and your thyroid appears to be functioning properly. Ignore the "t3" as it's not a real measurement of T3 (liothyronine) level. ...Read more
Total thyroidectomy 4 mo ago. High TSH & t4, low t3 (liothyronine). Feeling very hypo. Increases in levothyroxine not helping symptoms. Sliding downhill fast! Help!
Something does not sound right.
A high TSH with a high T4 is very uncommon.
It is possible, but unlikely that your pituitary gland is producing too much TSH.
You need to see your thyroid surgeon or your regular doctor as soon as possible. ...Read more
What does this mean?T3 (liothyronine) free normal, TSH normal, T4 categories-t4 high, t3u low, fti high.Tsh tested again 6 months later, lower but normal.On nuvaring only
Normal thyroid tests: Normal TSH level indicates normal thyroid function in the majority of cases. Normal free t3 (liothyronine) and normal freet4 usually support the fact. Total T4 (t4) can be high without excess thyroid when the thyroxine binding globulin (tbg), a thyroid hormone carrier, is elevated, as in pregnancy and while taking a bcp. Then t3 (liothyronine) (resin) uptake (t3 (liothyronine)u) is low and fti normal (tests now outdated should not be checked. ...Read more
What causes high TSH 7.0 (although normal t3, (liothyronine)t4,pth) and low cortisol (1.0)? Im being referred to an endo. Im worried.
I have a high TSH level 9.5 and normal T4 and t3 (liothyronine). Headaches and light headed. Also can this cause diabeties ?
Hypothyroid: You're hypothyroid. Headaches may get better when you get treatment from your doctor for your under active thyroid. ...Read more
My dad 70 years had high TSH 54 , low T4 0.4 and enlarged thyroid for 4 years. He has taken eltroxin since then . Can this turn into thyroid cancer?
Goiters due to hypothyroid conditions are benign and should settle down once replacement thyroxine has been used to control the problem. Cancer is rarely a concern in this situation, yet if the thyroid enlargement is substantial then you should consult an ENT doctor who deals with thyroid enlargements(or seek an endocrinologist 's opinion).
Good luck. ...Read more
32years old male high TSH level and normal T3 (liothyronine) and t4, 5.58 tsh//ft3, free, serum 4.92 , 3.2 ft4, fee, serum 17.5 , 1.36. Im on 75mg T4 didn't help fatigue.
The TSH is only minimally elevated and that may well be simply a lab error.
Your t3 (liothyronine) and T4 are near the top of the reference interval.
Put this together and it is unlikely that your thyroid labs are contributing to your fatigue.
Are you sleeping well?
Are you overweight?
You might need to have a sleep study. Please check with your primary care doctor. ...Read more
High TSH (7.12) accompanied by low cortisol (1.0). T4 and T3 (liothyronine) normal. What causes this? Mom had thyroid cancer. What tests should be done?
My daughter is 13 has a high TSH but normal T3 (liothyronine) t4. She has low IgA and white blood cell count of 57, 000 with chronic pain in left flank
High white blood cel count in a patient with low IgA level would suggest very srongly infection in some part of body, like respiratory, digestive or genitourinary systems.With pain in left flank may have infection in that area of body and she needs to be treated for this asap
high TSH with normal t3&t4 suggest subclinical hypothyroidism and may or may not treatment depending on level of tsh. ...Read more
Elevated TSH: Tsh (thyroid stimulating hormone) is produced by the pituitary gland in the brain. When the circulating thyroid hormone (produced by thyroid gland) is insufficient as in hypothyroidism, the TSH goes up. If there is too much circulating thyroid hormone as in hyperthyroidism, the TSH goes way down. So with your elevated tsh, i would guess you are hypothyroid. This is always confusing. Good luck. ...Read more
Probably so: You have subclinical hypothyroidism. Treatment is warranted. I would first address factors that indirectly affect thyroid function such as diet, vitamin deficiencies, other hormone imbalances (e.g. Estrogen dominance, adrenal fatigue), etc. If you have deficiency in iodine, selenium, vitamin d, iron, etc, your thyroid will be affected. Vitamin deficiencies are common. ...Read more
F/u with your Dr: Asymptomatic patients with an elevated TSH, but normal thyroxine levels, are referred to as having Subacute or Subclinical hypothyroidism. There are varying recs as to whether they should be treated, especially if no symptoms. I suggest f/u with your Dr to repeat tests in 3-6 months with thyroid peroxidase antibodies (TPO), to determine if persistent and risk for developing overt hypothyroidism. ...Read more
My wife is pregnant 6 weeks. at 5 week we found that she has high TSH (90) T4 ( 4.77). Doctor has started with levothyroxine 100 mcg.
High TSH 9.5, but normal T4 1.0. Mix of hypo and hyper symptoms. GP treating me as hypothyroid (Synthroid), but could I have a pituitary/other issue?
Your question is VERY smart.
It could be your pituitary- or other causes.
Overall Endocrinologists handle this complex thyroid question, so you may want to see one.
Stay well ...Read more
Unusual case: Hi. That is a VERY unusual lab picture, suggestive of either a TSH-secreting pituitary adenoma (you'd be hyperthyroid) or thyroid hormone resistance (thyroid hormone receptor defect...you wouldn't be hyperthyroid). To determine if you're hyperthyroid in this very rare case, you need to see an experienced endocrinologist. Good luck! ...Read more
