Introduction to Anti-TPO test

TPO is an enzyme produced by your thyroid gland. It plays a crucial role in the production of thyroid hormones, which help to regulate various body functions like metabolism, heart rate, and body temperature.

The Anti-TPO test, also known as the Thyroid Peroxidase Antibody test, is a blood test used to detect the presence of antibodies against an enzyme called thyroid peroxidase (TPO) in the blood. The immune system doesn't attack healthy tissues. However, in some cases, it mistakenly produces antibodies that target the TPO enzyme in your thyroid gland. This is known as an autoimmune reaction.

If you are experiencing symptoms like fatigue, weight gain, feeling cold, dry skin, anxiety, insomnia, and rapid heartbeat, these all signs indicate a thyroid disorder. Your doctor may recommend the Anti-TPO test if you experience thyroid disorder symptoms or have abnormal results on other thyroid function tests, like TSH. You can take the Anti-TPO test from Redcliffe Labs 

Test details in brief

What is the Anti-TPO test used for?

An anti-TPO test is done because: 

1. It helps assess overall thyroid health and checks for the underlying causes of thyroid dysfunction.
2. Your healthcare provider may suggest a test to diagnose thyroid autoimmune disease. The autoimmune disorder of the thyroid develops when antibodies begin to attack the thyroid tissues of the body, causing redness, swelling, and health complications. 
3. The anti-TPO test also helps monitor the progression and effectiveness of treatment for autoimmune disorders. 
4. Additionally, the test helps assess the risk involved in thyroid disorders in the future. 
5. Nevertheless, the test distinguishes between autoimmune disorders and other causes of thyroid dysfunction, such as goiter. 

Purpose of the Anti-TPO Test

The thyroid antibody test is used to detect the hypothyroidism or hyperthyroidism condition. Hypothyroidism is referred to as an underactive thyroid gland, while hyperthyroidism is referred to as an overactive thyroid gland. The test is used for the following purposes-

• The test helps to detect Hashimoto's Thyroiditis, which leads to decreased thyroid hormone production.
• This helps to detect the condition called hyperthyroidism that may lead to Graves' Disease. 
• High anti-TPO levels suggest an autoimmune cause for thyroid dysfunction, helping differentiate it from other causes like iodine deficiency.
• The test can be used to monitor the effectiveness of treatment for Hashimoto's disease. 
• In some cases, anti-TPO antibodies may be associated with fertility issues in women.
• In some cases, anti-TPO antibodies may be associated with fertility issues in women.
• If you have a family history of thyroid problems, the test might be used to assess your risk. 
• The thyroid anti-TPO test confirms whether you have already been treated for thyroid cancer. 
• The test also helps identify hypothyroidism. It is a condition that occurs due to reduced thyroxine hormone synthesis. 
• The test also helps assess the possible risk involved in the fetus in pregnant women with thyroid illness. 
• The anti-TPO helps determine whether you have an autoimmune thyroid condition or a non-autoimmune goiter. 
• Nevertheless, the test helps detect idiopathic myxedema. Although rare, it is an extreme form of hypothyroidism that occurs when the mucopolysaccharides accumulate in the skin and tissues, leading to swelling (edema). 

When should I get this anti-TPO test?

The anti-TPO test is done to diagnose an autoimmune condition affecting the thyroid. It is thyroid antibody testing, and you should get it done in the following circumstances: 

• Unexplained reason for hyperthyroidism: A physical exam and a thyroid hormone test may confirm the presence of an overactive thyroid, which may indicate Graves’ disease. Additionally, ultrasound and radionuclide thyroid scans may also be performed to diagnose Graves’ disease. 
• Subclinical hypothyroidism: The test also helps find out if they have high TSH and normal FT4 levels. Such conditions will lead to more severe hypothyroidism or remain subclinical without clear symptoms. 
• Goiter: The Thyroid gland enlarges abnormally, even if your thyroid hormone levels are normal. Your healthcare provider may suggest testing for TPOAb. 
• To monitor the treatment for thyroid cancer, The anti-TPO test may be suggested to monitor if the autoimmune thyroid diseases are progressing and the effectiveness of the treatment. 

What does the Anti-TPO test measure?

The Anti-TPO test measures antibodies in your blood, specifically targeting Thyroid Peroxidase (TPO), an enzyme your thyroid gland produces. These antibodies are called anti-thyroid peroxidase Antibodies. Your body starts making antibodies when your thyroid cells become damaged. The presence of anti-thyroid antibodies increases your risk of thyroid disease.

Your immune system doesn't attack healthy tissues. However, in autoimmune thyroid disorders, the immune system mistakenly produces antibodies that target the TPO enzyme, disrupting its function and potentially affecting thyroid hormone production. Thyroid peroxidase is an enzyme also stimulated by TSH. 

Preparation for the Anti-TPO test

The anti-TPO blood test is simple and, hence, does not require any special preparation. Here is what you must know and follow before the test- 

• No fasting is required. The anti-TPO blood test requires no fasting. You can eat and drink as per your daily routine.
• Medications- Consult all your medications and supplements with your doctors; they might affect your test results. 

Wear comfortable clothing. If you have any concerns about the anti-TPO test, consult your doctor before the test.

The procedure of the Anti-TPO test

Here is the step-by-step procedure of the Anti-TPO blood test-

• Step 1- The phlebotomist will tie a tourniquet or the band around your arm to locate the vein. 
• Step 2- Next, the healthcare provider will clean the arm area with an antiseptic solution to minimize the risk of infection.
• Step 3- After that, he will use a sterile needle to collect the blood. You might feel slight pain when the needle enters. 
• Step 4- He will collect the blood into a vial or tube. You might feel a slight pulling sensation during this step.
• Step 5- Once enough blood is collected, the phlebotomist removes the needle and applies pressure to stop bleeding. 
• Step 6- Next, he will put a bandage or cotton gauze at the puncture site to stop bleeding.

The entire procedure usually takes less than 10 minutes. You might feel slight discomfort or bruising at the puncture site, but this is normal.

What do the Anti-TPO test reports indicate?

After the sample collection, the blood test reports will be available within 24 hours. The test results are complex to interpret as the normal results may vary from different laboratories. Consult your test reports with your doctor. Here is what your anti-TPO blood test results may show-

If your test results show abnormal levels of thyroid antibodies, it might be due to an autoimmune disorder.

• Negative Result- The Anti-TPO normal range is less than 9.0 IU/mL. This indicates a low concentration of thyroid peroxidase antibodies in your blood. 
• Positive Result- A positive Anti-TPO test result indicates the presence of antibodies against thyroid peroxidase. This can be associated with autoimmune thyroid disorders- 

Hashimoto's Thyroiditis- This is the leading cause of hypothyroidism (underactive thyroid).

Graves' Disease- This condition can cause hyperthyroidism (overactive thyroid).

TPO antibodies are present in more than 90% of patients with hypothyroidism and 10% who do not have thyroid problems. These antibodies are high in 95% of Hashimoto's thyroiditis patients and 70% of Grave's disease. Even if you don't have thyroid disease, you might have TPO antibodies. 

Who should take the Anti-TPO test?

Your doctor may advise the thyroid antibody test to identify the following situations:

• Hypothyroidism (underactive thyroid)- Fatigue, weight gain, feeling cold, dry skin, hair loss, irregular or heavy periods, depression.
• Hyperthyroidism (overactive thyroid)- Weight loss, anxiety, insomnia, rapid heartbeat, heat intolerance, diarrhea, hand tremors.
• Subclinical hypothyroidism- If TSH is high and FT4 is normal, then testing for TPO will help to identify whether it's the beginning of hypothyroidism. 
• Goiter- This is the abnormal enlargement of the thyroid gland. Your doctor may recommend TPOAB testing if you have a goiter, even if your thyroid hormone level is normal.
• Abnormal Results on Other Thyroid Tests- If your thyroid function tests, like TSH (Thyroid Stimulating Hormone), show abnormal levels, further diagnosis with an Anti-TPO test might be needed. 

What are the common symptoms of Thyroid?

Your doctor may advise the thyroid antibody test to identify the following situations:

Common symptoms for Hashimoto's Thyroiditis:

• Weight gain
• Depression
• Joint Pain
• Fatigue
• Hair loss
• Low tolerance to cold

Common symptoms of Graves disease-

• Weight loss
• Bulging eyes
• Tremors
• Anxiety
• Swollen thyroid
• Low tolerance to heat
• Swollen thyroid (Goiter)

What is the risk associated with the anti-TPO test?

The risks associated with the anti-TPO test are as follows: 

• The risk involved with the anti-TPO test is that people with TPO antibodies are at a higher risk of thyroid disease after pregnancy. 
• As the anti-TPO test is a standard blood test, some possible risks include pain, bruising, or bleeding at the puncture site. Additionally, in rare cases, prolonged bleeding may also occur if you are taking blood-thinning medications. Consult your doctor to get immediate medical treatment.
