Slightly low platelets have little effect on regular medical examinations, and general entry-level medical examinations or civil service medical examinations are mainly designed to screen for infectious diseases. However, it should also be noted that if you join a company or go to the military to join the military, etc., the physical requirements are high, which may affect whether to pass. If the platelets are just a little low and other blood indicators are not abnormal, it means that there is no major health problem and the company will not reject it because of this. If the platelets are too low, it will seriously affect the blood clotting in the body and may lead to frequent bleeding or even spontaneous bleeding, which endangers the health. You must go to the local regular hospital for detailed examination to exclude whether there are serious blood system diseases such as hypersplenism, primary immune thrombocytopenia, aplastic anemia, leukemia, etc. If they exist, they should be hospitalized for regular treatment and should not be ignored.
