Overview
Antithyroid microsomal antibody is a test to measure antithyroid microsomal antibodies in the blood. Microsomes are found inside thyroid cells. The body produces antibodies to microsomes when there has been damage to thyroid cells. [1] [2] [3]
Differential diagnoses
A negative test is normal. A positive test may be due to:
- Autoimmune hemolytic anemia
- Granulomatous thyroiditis
- Hashimoto's thyroiditis
- Nontoxic nodular goiter
- Rheumatoid arthritis
- Sjogren syndrome
- Systemic lupus erythematosus
- Thyroid cancer
High levels of these antibodies have also been linked to an increased risk of:
Other risks associated with having blood drawn are slight but may include:
- Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
