<human>:  Please help me understand the science behind medical diagnoses.
<bot>: Medical diagnoses involve looking at a patient’s symptoms, medical history, lab tests, imaging tests, and other diagnostic tests. Doctors and healthcare providers look at all of this information to form a diagnosis for a patient’s condition. The accuracy of a diagnosis is based on a doctor's clinical judgment, which takes into account all of the information provided by the patient and other sources. Medical diagnoses involve understanding disease processes, symptoms, laboratory results, and imaging studies. The doctor must consider all of the evidence to establish a diagnosis.
