Checking your body for toxin levels requires a medical evaluation and specialized tests. Medical professionals can assess your exposure history and symptoms to determine the need for testing. Specific diagnostic tests often include blood and urine analysis to measure the presence and concentration of certain toxic substances.   These diagnostic procedures provide valuable information about your body's toxin levels and allow the doctor to accurately identify any potential health risks associated with exposure. It's essential to consult with a skilled healthcare provider who specializes in toxicology and environmental health to discuss your symptoms and concerns.
