The antibodies anti thyroperoxidase thyroid (anti TPO antibodies or ab TPO) are gods autoantibodies, that is, antibodies directed against our organism, in this case against the enzyme thyroperoxidase or thyroid peroxidase.

Anti-thyroid peroxidase antibodies

The antibodies to thyroperoxidase, also called anti thyroid peroxidase antibodies, ab anti thyroid peroxidase, anti tpo, or abtpo, they target thyroid peroxidase (thyroid peroxidase), which is the key enzyme for the production of thyroid hormones (T4 or thyroxine and T3 or triiodothyronine) starting from thyroglobulin.

They are called autoantibodies, as they attack structures in our own body.

There thyroid peroxidase, or thyroid peroxidase, it is an enzyme that promotes the iodination of tyrosine to form monoiodotyrosine (MIT) and diiodiotyrosine (DIT), which join together to give rise to thyroid hormones.

Antibodies to thyroperoxidase, together with antibodies to thyroglobulin and TSH receptor antibodies, constitute the so-called thyroid antibodies, also called anti thyroid antibodies.

Autoantibodies to thyroperoxidase are very common in autoimmune diseases of the thyroid, in particular the Hashimoto's thyroiditis it is characterized by the positivity of antibodies to thyroperoxidase in more than 90% of the affected persons.

Another autoimmune disease, the Graves' disease is characterized by  ab tpo positive in the 80% of cases it should also be said that antibodies to thyroperoxidase can be found in a small percentage of people with autoimmune diseases affecting organs other than the thyroid. In addition, about one in 10 healthy people have positive anti-thyroid peroxidase antibodies even in the absence of thyroid disease.

Finally, it can happen that these autoantibodies are measurable in the blood only after a certain period of time from the onset of the disease: in other words, a first check of antibodies to thyroperoxidase it can also be negative in the presence of autoimmune thyroiditis; in these cases, if the clinical suspicion is strong, this test must be repeated after a certain period of time to re-establish the positivity or confirm the negativity of the anti tpo autoantibodies.

The blood concentration of the antibodies to thyroid peroxidase the greater the likelihood of an autoimmune pathology affecting the thyroid gland, it is greater: there is therefore a certain relationship between the autoimmune activity responsible for the thyroid inflammatory process and the concentration of anti-thyroid peroxidase antibodies.

High thyroid peroxidase autoantibodies

Here are the causes of positivity of antibodies to thyroperoxidase, listed in order of frequency:

  • Hashimoto's thyroiditis: also called lymphocytic thyroiditis or chronic autoimmune thyroiditis is a fairly common disease. It is probably the most frequent cause of hypothyroidism in adults. In the initial phase of Hashimoto's thyroiditis, thyroid function may still be normal, while in the later stages subclinical hypothyroidism usually develops initially and then overt hypothyroidism, with high TSH and low fT4. The diagnosis is obviously based on the clinic and on the finding of the presence of high antithyroglobulin and antiperoxidase antibodies in the circulation. The antibodies to thyroglobulin they tend to be taller in the early stages of the disease, and then drop in distance, while the antibodies to thyroid peroxidase they usually remain high for many years after diagnosis.
  • Graves Basedow's disease: it is the most common cause of hyperthyroidism, often accompanied by goiter, ophthalmopathy (the typical "protruding eye") and rarely by dermopathy (myxedema at the pretibial level). Hyperplasia and overactivity of the thyroid are caused by circulating antibodies whose specific antigen is represented by the TSH receptor present on the surface of thyroid cells (thyrocytes). Anti TSH antibodies (anti TSH-R or TSH-R Ab) stimulate the thyroid to produce thyroid hormones in an exaggerated way. In this pathology, in addition to anti TSH antibodies, antibodies to thyroid peroxidase are found in over 3/4 of patients.
  • Granulomatous thyroiditis: or De Quervain's thyroiditis, is a sub-acute inflammation of the thyroid gland, generally triggered by a viral infection, which leads to the development of a transient hyperthyroidism which then results in hypothyroidism. Clinically, the disease manifests itself with myalgia (muscle pain), pharyngitis, low fever and asthenia (fatigue). Later, if the fever persists, pain and swelling (swelling) in the neck may appear. In a modest percentage of cases there are antibodies to thyroglobulin e positive anti thyroid peroxidase.
  • Sporadic thyroid goiter: it is the type of goiter that does not depend on environmental causes such as iodine deficiency (it is therefore not "endemic") but is caused by other factors such as thyroid pathologies or thyroid neoplasms.
  • Rheumatological diseases: such as systemic lupus erythematosus (SLE), Sjogren's syndrome and rheumatoid arthritis.
  • Immuno-haematological diseases: such as autoimmune hemolytic anemia, myasthenia gravis, pernicious anemia, and type 1 diabetes mellitus.
  • Neoplasms: such as colon cancer or thyroid cancer.
  • Pregnancy

      Hi, don't worry, you probably have a predisposition to thyroid autoimmunity that may lead you, perhaps, one day to develop hypothyroidism, but it will be enough to check your thyroid function periodically to keep this aspect under control. Show the tests to the doctor who will prescribe the appropriate checks.

    Hello, I'm 25 years old and I discovered celiac disease by chance two months ago. In the initial diet tests I have these TSH values: 6.1 (0.2-4.5), FT4 (free thyroxine) 15.6 (12-22), anti thyroglobulin 636 (<115), anti peroxidase 502 (<34), anti TSH receptor < 1 (ok if <1.75). Also considering my anxious state from having discovered celiac disease, the attending physician advised me to wait 6 months on a gluten-free diet, put the villi back in order and then do the tsh tests again, and then eventually go to the endocrinologist and start hormone replacement therapy. Perfect blood count, low ferritin (8 in a range between 8 and 140) and vitamin D (21 out of a range of 20). Agree?

        My doctor prescribed the tests for me following a series of symptoms including sudden weight gain with no lifestyle changes and severe changes in the menstrual cycle. In your opinion, if the situation is normal, why might you have asked me to perform an ultrasound of the neck?

          I guess he prescribed it to complete the diagnostic picture. Best regards

    Ab Anti Thyroglobulin (AbTg) 62
    what should I remove from the power supply

      Hi, I would say that they are not bad ... Blood cholesterol is just above normal levels, I would recommend containing as much as possible fatty foods and doing more exercise. As for the positive autoantibodies, the picture must be completed with the thyroid function if not already performed. However, please refer to your doctor who will give you what to do. Best regards

    I thank you infinitely. I got worried, so excuse the ignorance but is it normal to have these ab anti-tpo antibodies?
    I wanted to know so I have no autoimmune thyroiditis?
    Last question can these antibodies decrease or increase? I was told to take the exam again in September. I'm terrified.
    I thank you again infinitely.

      Thyroid peroxidase antibodies can be present in minimal quantities and this without correlating with autoimmune thyroid diseases. I cannot tell you for sure that they will not increase, the only way is to check them in a few months, following the instructions of the doctors who follow you. Best regards

    Hi I am a girl I am 23 years old they told me that I have aitoimmune thyroiditis because I have colloid cysts of 3 mm on the thyroid.
    I did a blood test with the following result:
    Tsh: 2.63 (reference values 0.35-3.70)
    Ft4 17.0 (reference values 10.0-22.7)
    Ft3 5.4 (reference values 3.5-6.5)
    S-ab anti Tpo 55 (reference values 0-60)

      I would say that thyroid function and autoimmunity are perfectly normal. Having a thyroid cyst does not mean having autoimmune thyroiditis. Do not fail to show these tests to your doctor. Best regards

      Have the examinations seen by the attending physician, an ultrasound of the thyroid gland and an endocrinological examination.

    my 24 year old daughter has been suffering from diabetes mellitus since the age of 3, she has a high tpo value of 865.4 the tsh is 3.88 the ft4 is 0.94 and the anti thyroglobulin is of 27.1 you can comment on these values. thanks

    • Testlevels 6 years ago

      Thyroid function seems normal, anti-thyroid peroxidase antibodies are high, probably there is a predisposition to autoimmunity also due to the presence of diabetes, tsh and thyroid hormones will need to be checked over time. In any case, always rely on the attending physician who follows you

    Good morning. I have a 14 year old daughter. We have seen slow growth and development. It is 1.45 meters high. and weighs 44 Kg. and has already "formed".
    We have carried out some analyzes and the results, outside the norm, are:
    AAT 246.8 (Reference value 0.0 - 4.1)
    ATPO 320.6 (Reference value 0.0 - 5.6)
    IGF1 627.3 (I don't understand the values of Ref.)
    At the moment he is under control at the Catania hospital in the Endocrinology department.
    Can I have your opinion? Thanks

    • Testlevels 6 years ago

      To answer her appropriately, it would be necessary to have the complete picture, in any case the girl denotes a predisposition to autoimmune, the endocrinologist department I think is the best place to clarify. Best regards

    Hi I have very high values, cholesterol at 146 ... FT3 at 3.28..the FT4 0.89..the AD ANTI TIREOGLOUBIN at 174 ... to be negative it must be below 40 instead the AD ANTI PEROXIDASE TIREOIDEA A 1102..for being negative must be under 35. should i worry?

    • Testlevels 6 years ago

      And the tsh?

    • Testlevels 6 years ago

      Anti TPO high, thyroid function is incomplete, TSH is missing.

  42. Adalcisa fish 6 years ago

    Hi I have the values that seem high to me .. cholesterol at 265..the Thyroglobulin at 11 ... TPO antibodies at 263..I have to worry..since I suffer from restless legs syndrome..and I had 2 meningioma operations to the orbital frontal brain ... thanks ... anyway I have to pay a visit to the enicrinologist shortly .. but in the meantime I wanted to know about these tests ... greetings ..

    • Testlevels 6 years ago

      Undoubtedly, cholesterol is high, and requires action in terms of physical activity and nutrition. Anti-thyroid peroxidase antibodies are high, but without the data of TSH, thyroxine and triiodothionine (T4 and T3), it is difficult to frame everything. Consult with the endocrinologist who will be able to indicate the most correct procedure. Sincerely
