Question 1

normal range tsh and free t3 but low t4?? just had my thyroid labs done - tsh - 1.88, free t3 - 3.3 and free t4 is .87. what would cause this? i dont sleep great with my 2yo waking up every night but why is t4 low? is t3 high?is this a bad balance?

Accepted Answer

: The Dr who ordered these tests knows your entire history and any current symptoms. They are the best resource for reading these labs in the correct context of your full medical history/exam/other labs. It would not be appropriate for a Dr online to try and determine a diagnosis based on two lines of information.

Question 2

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?

Accepted Answer

You need work-up: You should ask to be seen by an Endocrinolosit. Your question suggests that you may have low adrenal/thyroid function. Multiple gland "failure" is seen in a number of conditions. Certain blood/urine testing is indicated!
Good luck!
Hope this helps

Question 3

what to do if i have high t3, (liothyronine) t4 and normal, cause?

Accepted Answer

Thyroid: An elevated T3 (liothyronine) and T4 usually means that you have hyperthyroidism (over-active thyroid gland). Please check with your Primary doctor.

Question 4

what besides ms causes spinal cord lesion? mri shows t3/4 high signal lesion with well-defined borders. have l-side numbness chest-foot for weeks.

Accepted Answer

Spinal cord lesions: The differential diagnosis of ms like lesions in the cord include: spinal cord neoplasms (eg, astrocytomas, ependymomas), sarcoidosis, transverse myelitis, 
infarction of the spinal cord, 
vasculitis and 
radiation myelitis and subacute combined degeneration of the spinal cord (vitamin B12 deficiency) among other causes. This one finding needs to be correlated with your clinical symptoms and labs.

Question 5

my a.m. cortisol serum is routinely 35+ (range 9-21), but low dose suppression test was normal. tsh is slightly high, t3 (liothyronine) is elevated too. causes?

Accepted Answer

Oral contraceptive: The most likely explanation for these findings is being on an oral contraceptive (yaz).  This raises the cortisol binding protein level, making the total cortisol level look high, but the biologically active cortisol is normal.  The same thing happens for thyroid hormone, including T3 (liothyronine) levels.  If you have hashimotos and your TSH is high, you have mild hypothyroidism.

Question 6

what can cause high t3 uptake with normal t3 t4 tsh? also with low cortisol?

Accepted Answer

: If T3, T4 and TSH are normal, thyroid function is normal and T3 uptake result has no value. High T3 uptake only means the binding of T3 or T4 to thyroid binding globulin is high and this uptake was used in the past to interpret the result of total T4 when we couldn't measure free T4 but we now can, so T3 uptake test has no value. Low cortisol may increase thyroid hormone by increasing TSH level.

Question 7

is 4iu/ml thyroid peroxidase ab considered abnormally high or cause for concern? free t3 is 2.4pg/ml, does this mean i have hypothyroidism?

Accepted Answer

Need more info: 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, the most useful test for checking thyroid function is TSH level. The normal ranges may vary by the method used and the level should be checked against the reference range of the lab that did the test.

Question 8

possible causes of high rbw, high segmented neutrophils, low lymphocytes, low basophils, and high thyroglobulin ab., high t3 (liothyronine) uptake and ferritin?

Accepted Answer

Thyroid disorder: Are you on thyroxine? Or you have increased secretion of thyroxine from your thyroid you need to consult an endocrinologist to check your thyroid with isotope scan and ultrasound, increased ferritin reflects inflammation in your body mostly from the thyroid.

Question 9

age 42;wt: 61kg;t3-0.86, t4-9.60, tsh-1.91ng/ml;on thyroxine soudium 60mcg(past 16 years), lysteda for dub(past 3 years), ldl 160, reason for high ldl?

Accepted Answer

Genetic: Only about 10-15% of LDL  can be controlled by diet.  For many people,  the liver just makes too muich cholesterol.

Question 10

i have a high tsh level 9.5 and normal t4 and t3 (liothyronine). headaches and light headed. also can this cause diabeties ?

Accepted Answer

No: It can't cause diabetes, however if your TSH is elevated you should check with your doctor and get it treated with an appropriate dose of brand name t4. It's not abnormal enough to be causing symptoms like you're experiencing.
