These tests are commonly used in the evaluation of thyroid function and related conditions. If you have concerns about your thyroid health or other medical issues, it's important to discuss your symptoms and test results with a healthcare provider, who can provide you with a proper diagnosis and treatment plan if necessary.

1. Thyroid Total: This typically refers to a blood test that measures the total amount of thyroid hormones in the blood. It usually includes both thyroxine (T4) and triiodothyronine (T3). These hormones are produced by the thyroid gland and play a crucial role in regulating the body's metabolism.

2. Thyroid Free: This usually refers to the measurement of free thyroxine (FT4) and free triiodothyronine (FT3) in the blood. These are the active, unbound forms of T4 and T3 that are available to the body's cells for use. Free thyroid hormone levels are often a better indicator of thyroid function than total levels, as they reflect what's available for use.

3. Glucose: This is a measure of the concentration of glucose (sugar) in the blood. It's commonly used to diagnose and monitor diabetes, as well as to assess how effectively the body is managing blood sugar levels.

4. Hemoglobin: Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Hemoglobin levels are often tested to check for anemia or other blood disorders.

5. Anti TPO (Thyroid Peroxidase Antibodies): This test measures the level of antibodies against thyroid peroxidase in the blood. Elevated levels of anti-TPO antibodies are often associated with autoimmune thyroid diseases, such as Hashimoto's thyroiditis and Graves' disease. These antibodies can attack the thyroid gland and disrupt its normal function.
