Brief Answer:

Detailed Answer:
Hello,
Thanks for posting your query.
Microsomes are found inside thyroid cells. The body produces antibodies to microsomes when there has been damage to thyroid cells. The antithyroid microsomal antibody test measures these antibodies in the blood.
This test is done to confirm the cause of thyroid problems, including Hashimoto thyroiditis.

The test is also used to find out if an immune or autoimmune disorder is damaging the thyroid.
A positive test may be due to:

Granulomatous thyroiditis
Hashimoto thyroiditis
Important: A positive result does not always mean that you have a thyroid condition or that you need treatment for your thyroid. A positive result may mean that you have a higher chance of developing thyroid disease in the future.

Antithyroid microsomal antibodies may be seen in your blood if you have other autoimmune conditions, including:

Autoimmune hemolytic anemia
Autoimmune hepatitis
Autoimmune adrenal disease
Rheumatoid arthritis
Sjögren syndrome
Systemic lupus erythematosus
You may need an ultrasound, biopsy, and radioactive iodine test to narrow down your diagnosis. You’ll probably need blood testing every few months until your condition is under control.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Wishing you good health.
Regards.
Dr. Praveen Tayal.
