Thyroid Tests
Thank you for shopping our thyroid tests. A properly functioning thyroid is crucial to healthy living. A cheap blood test can help diagnose thyroid disease and prevent it. A thyroid-stimulating hormone or TSH lab test can help determine whether you have either hyperthyroidism or hypothyroidism, both of which can interfere with your appetite, heart rate, and energy levels. Order a thyroid blood test today and see whether or not your thyroid is operating at an optimal level! Thyroid tests are among the most important health screens a patient can complete, as more than 12% of Americans will develop some form of thyroid condition in their lifetime, and more than 20 million of us are currently living with some variation of thyroid disease. Thyroid tests from Walk-In Lab are some of the most affordable health screens on the market and should be a part of any annual preventive health exam. A number of these tests are also used as thyroid cancer blood tests to monitor the effectiveness of treatment. Order online without insurance or a doctor's order. Feeling tired? Not sleeping well? Gaining or losing weight for no apparent reason? These are just some of the possible side effects of hyper or hypothyroidism. Choose from either blood, urine, or saliva TPO tests from Walk-In Lab to help you determine if your levels are normal. Some panels include a complete blood count (CBC), complete metabolic panel (CMP), and other vital screens that can uncover other, unrelated health issues.
