What is the normal range for thyroid antibodies blood test?

Thyroid Antibody Test Results Normal values are: TPO antibody: Less than 9 IU/mL. Thyroid-stimulating immunoglobulin antibody (TSI): Less than 1.75 IU/L. Anti-Tg antibody: Less than 4 IU/mL.

What is high TPO antibodies?

Values above 9.0 IU/mL generally are associated with autoimmune thyroiditis, but elevations are also seen in other autoimmune diseases.

Does high TPO mean Hashimoto’s?

High levels of TPO antibodies may be indicative of autoimmune thyroid disease. On their own, the presence of TPO antibodies does not necessarily mean hypothyroidism. Instead, Hashimoto’s is the most common cause of hypothyroidism.

What happens if thyroglobulin is high?

Your thyroglobulin levels are high and/or have increased over time. This may mean thyroid cancer cells are growing, and/or cancer is starting to spread. Little or no thyroglobulin was found. This may mean that your cancer treatment has worked to remove all thyroid cells from your body.

What is thyroglobulin antibody test for?

What levels indicate Hashimoto’s?

If your TSH level falls under 0.5 mIU/L, this indicates that you have an overactive thyroid (hyperthyroidism). Numbers above the normal range, usually 5.0 mIU/L or higher, show that you may have hypothyroidism.
