My blood test showed an elevated level of tg antibodies. Does that mean I have cancerous cells running around? Had papillary thyroid cancer a year ago

My blood test showed an elevated level of tg antibodies. Does that mean I have cancerous cells running around? Had papillary thyroid cancer a year ago

Not necessarily.: Having elevated tg antibodies primarily means that the more important tg test itself will be falsely lower than its true value. (no conversion formula exists.) if your tg antibodies are only 20 or so, with an undetectable tg level, it is hard to know what that means. If your tg antibodies are much higher, then concern for the presence of thyroid cancer would increase. ...Read more

I am having extreme fatigue and I did blood test and my TSH level was high (8.6)! but thyroid hormones are normal (t3 (liothyronine) T4)! what is causing fatigue?

Further testing: The fatigue may be still be related to the thyroid. You should have a full thyroid panel which would include total and free T4 and t3, (liothyronine) rt3 and fti as well as thyroid autoantibodies. There can be defects in conversion from inactive to active hormone or an autoimmune process may be active. If that is the case treatment may include some hormone replacement but also addressing the immune system. ...Read more

Hi, I just had my blood test results and the thyroid peroxidase ab level is 1122.18 iu/ml. What does that mean? I visited the dr feeling tired

Important info: B"sd The TPAb is specific for thyroid peroxidase enzyme. Its occurence is highly related to genetic susceptibilty to Hashimoto's thyroiditis.

Just had a blood test that showed Thyroid level: T4 1.9 TSH 0.07. Have appt. With endo in 3 weeks am very worried. What does this mean? Graves disease

Hyperthyroid: It appears that your FT4 is high, and TSH low, which indicates hyperthyroidism. And it appears you have symptoms (palpitations? Sweating? tremor?). Graves disease is the most likely cause. Don't worry. This can be controlled and treated, usually starting with medications (eg. methimazole, b-blocker) and then you should discuss radioactive iodine with your endocrinologist. ...Read more

If you are talking about T4 or T3 (liothyronine) (free or total) then high levels indicate an overactive thyroid. ...Read more
