Thyroid Lab Tests (A-Z)
This test is used to measure the amount of Iodine in the blood. Too little or too high of Iodine in the blood may play an important contributing factor in thyroid disease and conditions.
Measures the amount of parathyroid hormone and calcium. PTH helps regulate calcium, vitamin D, and phosphorus levels in the blood and bones.
Measures the amount of intact parathyroid hormone to evaluate parathyroid function and abnormal calcium levels.
Measures the level of Reverse T3, that may inhibit the action of the T3 hormone.
This Ayumetrix at home test kit measures the amount of Reverse T3 to help evaluate thyroid function.
Measures the amount of freely circulating triiodothyronine (T3) to evaluate thyroid function.
Measures the total amount of triiodothyronine, T3, to evaluate thyroid function.
Measures the amount of proteins in the blood that are capable of carrying a thyroid hormone.
This Ayumetrix at home test measures the amount of freely circulating triiodothyronine (T3) to evaluate thyroid function.
Measures the amount of free thyroxine (T4) to evaluate thyroid function.
This Ayumetrix at home test kit measures the amount of free thyroxine (T4) to evaluate thyroid function.
The Thyroglobulin Antibody test may be ordered when an individual has symptoms of a thyroid disorder or to evaluate treatment of thyroid cancer.
Measures the amount of thyroid peroxidase (TPO) antibodies to help understand the cause of thyroid disorders.
This Ayumetrix at home test kit measures the amount of thyroid peroxidase (TPO) antibodies to help understand the cause of thyroid disorders.
Measures T3 Uptake, T4 and T7
Measures the amount of thyroid-stimulating hormone (TSH) to evaluate thyroid function

Does Thyroid Testing Makes Sense for Me?
Your thyroid gland, located in the front of your lower neck, produces hormones that regulates your mood, energy levels, and metabolism. It produces two main hormones, T3 (triiodothyronine) and T4 (thyroxine), that influence a wide range of critical functions.
Feeling tired all the time? Do you have sudden weight gain or weight loss for no clear reason? These are both common symptoms of hypothyroidism. Experiencing persistent dry skin? Is your heart rate fast? These all are signs that you may have a thyroid problem such as:
- hyperthyroidism (overactive thyroid)
- hypothyroidism (underactive thyroid)
- thyroiditis (inflammation of gland)
- Graves' disease (a common cause of hyperthyroidism)
- Hashimoto's disease (a common cause of hypothyroidism)
- thyroid nodules (a common cause of producing too much thyroid hormone, either T3 or T4)
- thyroid cancer
According to the American Thyroid Association (ATA), thyroid disorders affect more than 20 million Americans, with more than 60% being unaware of their condition. The ATA recommends thyroid testing via a blood test for adults every 5 years starting at age 35. Thyroid screening is also prescribed for women during pregnancy and the postpartum period. Studies show women to be eight times more likely than men to experience a thyroid problem.
We measure your levels of thyroid hormones starting with thyroid stimulating hormone, commonly known as a TSH test. Measuring TSH levels is typically the first step to evaluate thyroid function. If abnormal levels of TSH are indicated, medical advice is normally to follow up with a T4 test (total T4 or free T4 levels). Other recommended follow up testing include t3 tests and measuring thyroid antibodies, particularly thyroid peroxidase (TPO) antibodies.
Health issues may be a result of pituitary gland function or there may be other factors contributing to a thyroid condition. In some cases, a thyroid scan using radioactive iodine may be utilized to diagnose the problem. However, the easiest first step to determining the cause of a thyroid problem is a thyroid blood test.
What do my thyroid test results mean?
Thyroid function tests are laboratory blood tests that measure your thyroid hormone levels and compare them to a normal range which can vary across laboratories. View sample thyroid test results with lab variations, ranges and explanations. Thyroid blood test results are a valuable tool for individuals with certain thyroid health concerns.
Following is a simplified summary of normal ranges for each of the thyroid hormones:
- TSH: between 0.4 and 5.0 milli-international units per liter (m IU/L). But, many scientists and doctors believe that some individuals do have thyroid malfunctions with a TSH above 2.5 instead of 5.0
- T3: between 80 and 180 nanograms per deciliter (ng/dl)
- T4: between 4.6 and 12.0 micrograms per deciliter (ug/dl)
- Free T4: between 0.7 and 1.9 ng/dl
