T3 Uptake LabCorp

The T3 Uptake test from Defy Medical helps measure how well your thyroid gland is working by assessing how much thyroid hormone is binding to proteins in your blood, which can help identify thyroid conditions causing your symptoms. This test is useful because it can indicate if your thyroid hormone levels are too low or too high, providing clues to the cause of your symptoms. Getting this test can help your doctor determine the right treatment plan to address your specific condition.

Finding the cause(s) of:

• Cold intolerance: This test can help identify hypothyroidism, a condition where the thyroid doesn't produce enough hormone, often causing sensitivity to cold.
• Dry skin: Low thyroid hormone levels, potentially detected by this test, can lead to changes in skin, including dryness.
• Fatigue: This test can help uncover thyroid dysfunction, such as hypothyroidism, which is a common cause of persistent tiredness.
• Hair loss: Thyroid problems, which this test can help diagnose, are known to sometimes cause hair thinning or loss.
• Thyroid swelling: While this test measures hormone binding, it's often ordered alongside other thyroid tests to investigate thyroid gland issues, potentially including swelling.
• Weight gain: This test can help detect hypothyroidism, a condition where slowed metabolism due to low thyroid hormone can contribute to weight gain.
