A blood test has shown thyroid peroxidase ab is 62.8 ku/l does this raise mean I have hashimoto’s?

A blood test has shown thyroid peroxidase ab is 62.8 ku/l does this raise mean I have hashimoto’s?

Not necessarily...: The first question is why was the test done? If because of abn thyroid labs &/or an abn thyroid ultrasound I would be highly suspicious. Although this value is tech elev it is only min so. This COULD be early Hashimoto's, but values with active Hashimoto's are often as high as the thousands. Diff labs also have diff ways of measuring TPO & can give mildly abn values at times. Need more info... ...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

The TPAb is specific for thyroid peroxidase enzyme. Its occurence is highly related to genetic susceptibilty to Hashimoto's thyroiditis. The most common condition associated with hypothyroidism, occasionaly hyperthyroidism. There is also an increased incidence of thyroid nodules, so in my practise in addition to thyroid function tests, a thyroid US would be done. Glad to discuss further. ...Read more

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

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
