The exact preoperative tests depend on your age, medical history, medications, BMI, smoking status, and whether you are having breast augmentation alone, liposuction 360 alone, or both together. Common tests before elective surgery often include a CBC, basic metabolic or comprehensive metabolic panel, pregnancy test when applicable, and sometimes coagulation studies. Depending on your history, your surgeon or anesthesiologist may also request an EKG, chest X-ray, medical clearance, or additional labs such as A1c, thyroid testing, or nicotine testing. For breast augmentation, an MRI is not routinely required before surgery for most patients who do not already have implants and have no breast symptoms. Breast imaging may be recommended based on age, personal or family history, a breast mass, abnormal exam, or your local screening guidelines. In those cases, mammogram or ultrasound is more commonly used first. MRI is usually reserved for specific indications, such as evaluating implant rupture in someone who already has silicone implants or clarifying certain breast findings. For liposuction 360, your surgeon will also consider the planned volume, anesthesia type, and overall safety. Ask your surgeon for a written pre-op checklist tailored to your procedure and health history, and make sure all testing is reviewed before surgery.
