From producing energy and regulating body temperature to keeping your brain, heart, and muscles working normally, thyroid hormones contribute to a wide range of functions throughout the body. It should then come as no surprise that an imbalance in these hormones can cause an endless array of symptoms and health problems. An overactive thyroid can be indicative of a potentially serious condition like Grave’s Disease, while an underactive thyroid can also lead to a host of medical issues. Biolab’s BioThyroid test package measures TSH, FT4, FT3, and TPO levels – all of the key indicators of thyroid function. If you’re experiencing unusual weight loss or weight gain, low energy, heart palpitations, excessive sweating, or any other host of symptoms, this test is vital to ruling out a potential thyroid imbalance.
