I have the following test results for thyroid. any one know if this is normal?
Question:
Thyroglobulin Antiobodies <20
Thyroid Peroxidase Antibodies <10
T-3 229 mg/dl
T-3 uptake 19%
T-4 14.5mcg/dl
Free T-4 2.8
TSH .18MIU/L
Anyone have any info on this?
Answers:
You T4 and free T4 are raised and your TSH is low, this looks like an overactive thyroid.
(Unfortunately I have struggled a bit with that interpretation because the lab we use does all the tests in different units.)
T3-Normal 100 to 200 ng/dL (nanograms per deciliter)
You have got 229 ng/dL.
Greater-than-normal levels (T3) may indicate:
* hyperthyroidism (for example, Graves' disease)
* T3 thyrotoxicosis (rare)
* thyroid cancer (rare)
T3 resin uptake-Normal values(RT3U)-24% to 37%.
You have got 19%.
Lower-than-normal levels (RT3U) may indicate:
* acute hepatitis
* hypothyroidism
* hypothyroidism; primary
* hypothyroidism; secondary
* pregnancy
* estrogen administration
T4-Normal values 4.5 to 11.2 mcg/dL (microgram per deciliter)
You have got 14.5 mcg/dL.
Greater-than-normal levels of T4 along with low levels of TSH may indicate hyperthyroid conditions, such as:
* Graves' disease
* Toxic multinodular goiter
* Subacute or chronic thyroiditis
* Early Hashimoto's disease
* Iodine-induced hyperthyroidism
* Germ cell tumors
* Trophoblastic disease
Since you have got higher levels of TSH, the above disease conditions need not apply.
Normal values (TSH) are from 0.4 to 4.0 mIU/L for those with no symptoms of an under- or over-active thyroid.
You have got 18 mlU/L.
Greater-than-normal levels (TSH) may indicate:
* Congenital hypothyroidism (cretinism)
* Primary hypothyroidism
* TSH-dependent hyperthyroidism
* Thyroid hormone resistance
* Exposure to mice (lab workers or veterinarians)
Normal value ranges may vary slightly among different laboratories. Consult your Endocrinologist.
