||Composed of three modules - laboratory medicine, diagnostic imaging, and ECG. Students gain competence in assessing and interpreting diagnostic tests, and learn basic clinical laboratory determinations and values and their correlation with normal and disease states. Practical sessions are given in urinalysis, hematology (CBC, hematocrit), and microbiology (Gram staining, pure culture techniques, antibiotic spectrum). Imaging modalities and their role in clinical medicine are introduced, with emphasis on conventional radiography and some discussion of ultrasound, CT, and MRI. Included are studies of the chest and abdomen, GI series, GU radiology, examination of extremities, and mammography. Basic concepts in ECG interpretation are taught, including principles of ECG tracings, rate and axis determination, and recognition of abnormal tracings.
