Regular health checkups are crucial for preventing chronic illnesses. Dr. Rocio Salas-Whalen highlights five life-saving blood tests: Lp(a) for heart disease risk, ApoB for assessing LDL particle impact, ApoE for Alzheimer's predisposition, OGTT/HbA1c for diabetes detection, and CMP for organ function. These tests can identify risks long before symptoms manifest, empowering individuals to take proactive health measures.
