Entry-level physical examinations can be performed during the physiological period. The routine items of entry-level physical examinations include internal medicine, surgery, ophthalmology, otorhinolaryngology, stomatology and items of blood sampling and laboratory tests, such as blood glucose, blood lipids, liver function, kidney function and blood routine. In addition, there are also front and side views of the chest, electrocardiogram, and ultrasound examinations of the liver, gallbladder, pancreas, spleen, kidney and breast. Basically, all of the above items can be checked during the physiological period, but it should be clear that routine urine examination should be postponed. However, it is necessary to postpone the routine urine test because it is likely to contaminate the urine specimen during the physiological period, resulting in a false positive result for red blood cells in the urine. In addition, gynecological vaginal examinations should not be performed during the physiological period. Therefore, it is important to know these precautions in advance and to communicate with the health check staff.
