How long does it take for a hashimoto's disease (anti-thyroid peroxidase) ab to come back?

How long for results. Was that your question? Anywhere from 1 to 4 days in my experience. I generally don't check, because they really rarely have any impact on the management of thyroid disease.

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...

Lab tests showed the following: ANA w/titre & pattern 1:320 and a thyroid peroxidase ab 484.0...Could high ANA be because of positive hashimoto's?

No. Hoshimoto's is an autoimmune disease. ANA is elevated in autoimmune diseases. Hoshimoto's doesn't cause the elevated ANA but an autoimmune state causes both the elevated ANA and thyroid antibodies which cause hoshimoto's. Read more...

Does a lab result of thyroid peroxidase ab of 484.0 confirm hashimoto's even though anti thyroglobuline abs are <20.0?

Highly suggestive. Anti-thyroid peroxidase (anti-tpo) autoantibodies is supportive evidence for a diagnosis of graves disease in patients with thyrotoxicosis. The highest tpo antibody levels are observed in patients suffering from hashimoto thyroiditis. In this disease, the prevalence of tpo antibodies is about 90% of cases, confirming the autoimmune origin of the disease. In 60%–80% occurs also in graves disease. Read more...
Yes. Patients with autoimmune (hasimoto's) thyroiditis not infrequently have one but not both anti-thyroid antibodies. Read more...
