Blood Tests

Common Types of Blood Tests

- Complete blood count (CBC): Measures red blood cells, white blood cells, and platelets.
- Basic metabolic panel: Assesses electrolyte and glucose levels.
- Coagulation factors: Evaluates the ability of blood to clot.
- Autoimmune and immune-system tests: Detect specific antibodies and proteins related to autoimmune diseases.

Fasting Requirements

For most blood tests, fasting for up to 12 hours is required. Consult with your doctor for specific instructions on medications that can be taken the night before.

Hormone Imbalances

- Thyroid-stimulating hormone (TSH): Controls thyroid hormone secretion. High levels indicate hypothyroidism (underactive thyroid), while low levels suggest hyperthyroidism (overactive thyroid).
- Testosterone: A sex hormone produced by both men and women. Low levels can lead to various health issues, including abdominal obesity, bone problems, and heart disease.

Causes and Symptoms of Hormone Imbalances

Hormone imbalances can disrupt health and well-being. Thyroid imbalances can cause a range of symptoms or none at all. Testosterone imbalances can manifest as reproductive issues, mood changes, and physical changes (e.g., unwanted hair growth).
