Anti TPO test cost with insurance
Most of the health insurance policies in the U.S. cover the cost of the anti-TPO test. However, the coverage offered by private health insurance companies and national health insurance programs like Medicare and Medicaid varies widely. So we recommend you to check the coverage of your plan with the insurance company before getting tested.
Our anti-TPO testing providers do not accept any health insurance plan. But, on request, they can provide you with an itemized receipt containing all the details like the name and code of the test, and CPT code which is necessary for insurance reimbursement purposes.
What is a TPO antibodies test?
TPO refers to thyroid peroxidase. It is an enzyme found in the thyroid gland that plays an important role in the production of thyroid hormones. Anti TPO antibodies are produced by the immune system against the enzyme when the immune system mistakenly attacks the healthy thyroid cells and this is known as an autoimmune response. This can result in an autoimmune thyroid disorder causing chronic inflammation or tissue damage of the thyroid gland.
Why is an anti-TPO test done?
An anti-TPO test is mostly done to detect and diagnose autoimmune thyroid disorders. Your physician will order an anti-TPO test if you show signs and symptoms of Hashimoto’s disease (an autoimmune disorder in which the thyroid gland is destroyed gradually) or Grave’s disease (an autoimmune disorder that causes hyperthyroidism or overactive thyroid) or if other thyroid tests like TSH test (thyroid-stimulating hormone) and TFT (thyroid function test) indicate low or high thyroid hormone levels.
Symptoms of Hashimoto’s disease
- Sensitivity to cold
- Abnormal weight gain
- Body pain
- Pain in the joints
- Irregular menstrual periods
- Loss of hair
Symptoms of Grave’s disease
- Abnormal weight loss
- Puffiness in the eyes
- Shaking hands
- Sensitivity to heat
- Rapid and irregular heartbeat
- Swollen thyroid
- Sleeping trouble
An anti-TPO test will also be ordered when a pregnant woman has autoimmune thyroid disorders to assess the thyroid gland of the baby.
Thyroid peroxidase antibodies normal range
The normal range of TPO antibodies is less than 35 IU/mL (international units per milliliter).
How is the thyroid antibodies test performed?
During this test, a lab technician or a phlebotomist will cleanse the area to be injected with a disinfectant and wrap an elastic band around the upper arm to make the vein visible and pool with blood. He/she then injects a needle to draw a sample of blood and collects the sample in a vial (a glass container) or a test tube. After the blood sample is drawn, you will be asked to apply pressure on the puncture site with a cotton ball to stop bleeding. The collected blood sample is then sent to the laboratory for further testing.
It takes less than 5 to 10 minutes to perform this test.
Is there any special preparation required before the test?
There is no special preparation required for an anti-TPO blood test. But it is very important to inform your physician if you are on any medications as they may interfere with the results and result in an inaccurate diagnosis.
Are there any risks to the test?
There are no possible risks or complications in the TPO antibodies test. But sometimes after the blood sample is drawn, you might feel dizziness, slight pain, bruise, soreness, or redness in the injected area for a very little period.
What does the TPO antibodies test result mean?
If your test results are negative, it indicates that TPO antibodies are not present in the blood and the symptoms of thyroid disorder are not caused by an autoimmune disease. Even though the test results are negative, if your physician suspects of you having an autoimmune disease in the future, you will be asked to take an anti-TPO test at regular intervals.
If your test results are positive, it indicates that TPO antibodies are present in the blood and you have an autoimmune thyroid disorder. Your physician will prescribe some medicines to treat and manage autoimmune thyroid disorders.
