Whether a cold can be examined depends on the degree of the cold, as follows: 1. If there is a little cold, such as a runny nose or nasal congestion symptoms, it will not affect the physical examination; 2. If there is an obvious upper respiratory tract infection, including coughing, coughing, or even bronchitis, pneumonia symptoms, the physical examination results will often show that there are abnormal indicators of viral or bacterial infection, such as blood routine white blood cells will rise or fall, and the ratio of lymphocytes and neutrophils will also be affected. The proportion of lymphocytes and neutrophils will also be abnormal; 3. In particularly serious cases, blood biochemical tests, including liver function and transaminase indicators, will also be affected. So if you are dealing with a more important physical examination, it is best to have a physical examination after the cold has completely healed. If you just know your health condition, a comprehensive health checkup will not affect much if you have mild symptoms. And other health conditions can be ruled out by the analysis of this indicator.
