TSH suppressed, T3 (liothyronine) and FT3 (liothyronine) in the left side of normal range, T4 in the middle and FT4 low out of range. Can it be thyrotoxicosis? how can FT4 be low??

TSH suppressed, T3 (liothyronine) and FT3 (liothyronine) in the left side of normal range, T4 in the middle and FT4 low out of range. Can it be thyrotoxicosis? how can FT4 be low??

Not really: Thyrotoxicosis happens when your thyroid gland has gone haywire and is pumping out "tons" of thyroid hormone. Not so according to what you say. You may be going to someone who is trying to treat the lab, not the patient. Also, study some statistics, if not from a book with a friend or the net ...Read more

What are the symptoms of low t3 (liothyronine) levels?

What are the symptoms of low t3 (liothyronine) levels?

Maybe none: T3 (liothyronine) & T4 are the active thyroid hormones. But low T3 (liothyronine) by itself may be normal, unless either T4 is low or TSH is elevated, then total thyroid production is likely low. See your doctor for full evaluation and treatment. ...Read more

Can you get hypothyroid symptoms from low levels of t3 (liothyronine) only? Would this be treated?

Doubtful: The T3 (liothyronine) test is not as reliable as the free T4 test and it is not rare to see patients with somewhat low or high T3 (liothyronine) levels whose thyroid is working properly. If your total or free T4 and your TSH are normal I would not be concerned about your T3 (liothyronine). We mainly treat when TSH is elevated. ...Read more

I'm converting T4 into T3 (liothyronine) well and although I've lots of T3 (liothyronine) it is not getting into my cells.I still have lots of symptoms.Im on 200mcg levo.Need help.

T4 and T3 (liothyronine): T4 and T3 (liothyronine) are standard items and I don't understand your statement that "T3 (liothyronine) is not getting into your cells". 200 mcg of Levothyroxine is quite a dose for a 23 year old, and it is only prescribed if your thyroid glands have been removed or are not working. I would very much appreciate getting more information from you and/or your doctor. ...Read more

I have secondary hyperparthyroidism. Could this be grave's undetected if my T3 (liothyronine) levels are off. I have PHP 1B too. I have symptoms of Grave's.

UNLIKELY: You do not diagnose Graves Disease by having abnormal T3 (liothyronine) level You need to have a full thyroid profile including TSH,T4,T3 (liothyronine) (liothyronine) AND FREE T4 You will have low TSH and High T4/Fee T4 and T3 (liothyronine) Another test which is sometimes done is Thyroid Stimulatin Antibody Test (TSI) IF TSH,T4 T3 (liothyronine) LEVELS are equivocal and you have symptoms and signs of Graves Disease as it is an an Auto Immune Disease ...Read more

I've been on levothyroxine for three weeks and almost feel like my symptoms are worse. Both my t4 and my t3 (liothyronine) are low, the most bothersome symptoms ach?

Dosage adjustment: Usually, most cases of hypothyroidism are treated with increasing doses of l-thyroxin until all levels of T3 (liothyronine). T4 and TSH are normalized. This is determined by routine blood testing including checking for anti- thyroid antibodies to rule out autoimmune ( Hashimoto's) thyroiditis. ...Read more

Which test results are more important: T3 (liothyronine) total or free t3 (liothyronine)? If total t-3 is low and free t-3 is low, almost out of range w/symptoms, treatment?

Which test results are more important: T3 (liothyronine) total or free t3 (liothyronine)? If total t-3 is low and free t-3 is low, almost out of range w/symptoms, treatment?

Free results,,,: The most important result by far is the freet4 as this indicates how much available active thyroid hormone is circulating. Free t3 (liothyronine) is also important as T4 is converted into t3 (liothyronine) and is more active. Tsh is also important as this and free T4 help indicate whether or not a person is hypothyroid. But free results are more important as this indicates the amount of active hormone. Good luck. ...Read more

Low T3 (liothyronine) over a year & free T3 (liothyronine) borderline low though in range, have all symptoms of hypothyroidism. Is it unheard of to treat w/meds to see if it helps?

Low T3 (liothyronine) over a year & free T3 (liothyronine) borderline low though in range, have all symptoms of hypothyroidism. Is it unheard of to treat w/meds to see if it helps?

Many docs would Rx: The "normal range" is where 95% of folks lie, but I believe at least 20% of people are clinically hypothyroid & about 3/4 of those have "normal tests." I find most patients who are hypothyroid remain symptomatic until their Free T3 (liothyronine) is in the upper half of the range. If you have the symptoms of hypothyroidism & borderline low labs try Rx. See http://tinyurl.com/koyamo5 & http://tinyurl.com/pxz8mkd ...Read more

Hypothyroidism-?levels 1.06tsh, T3 is 2.3. 1.better to treat symptoms or numbers for hypothyroidism ?2. Synthroid (thyroxine) or Levothryxine  brand better?

Brand Synthroid (thyroxine): Levothyroxin (LT4)=generic name for thyroid hormone. There are sev brands with Synthroid being best known (Levoxyl, Unithroid...)Each dose has about the same amount of LT4, but the FDA allows some variability. They also use diff fillers, which changes absorption. Tiny dose changes make a big diff in some people & diff brands can be like a diff dose in some. If poss take the same brand each refill! ...Read more

Hypothyroid symptoms: T4 free .08, T3 (liothyronine) free 2.4, TSH 3rd generation .07 . Doesn't make sense?

Stop the pig!: You're taking armour thyroid, which is ground up pig and not calibrated by how much thyroid is in it, but by iodine content. It is worthless and armour plus T3 (liothyronine) is very dangerous therapy. That's why your lab is all wrong. Stop getting your medical info from the internet. Get on brand name T4 instead and let a real doctor help you control your thyroid levels. ...Read more

Thyroid: No, it is not ok. Please have your doctor check the results because t3 (liothyronine) and T4 are essentially in range but TSH is quite low and you and your doctor need to know why. The minor high level of free t3 (liothyronine) is not enough to suppress your tsh. ...Read more
