My antibody thyroglobulin test results sent to me via email is confusing. my range is; <1.8 iu/ml standard range is <4 0 no other info given ?

Antithyroglobulin: Since this result is not abnormal, it signifies no autoimmune disorder of the thyroid like hashimoto's hypothyroidism. An endocrinologist or thyroidologist can evaluate your thyroid status if you have further concerns.

Negative : Your thyroglobulin antibody test is negative. The &lt;1.8 is/ml is likely the lowest detectable that the machine can read. Your test is essentially undetectable.
