Blood tests are generally referred to as blood tests. Clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, bone marrow cytology tests, blood grouping and cross matching tests, and can detect hematological signs of common blood diseases. Because the blood is taken as a detection object, the blood is rich in nutrient substances such as protein, microorganisms and the like, the blood can not only provide a nutrition base for human life health, but also be a hotbed for propagation of bacteria, viruses and the like. The isolated blood is less protected by the human immune system and therefore has a higher probability of being infected with bacterial viruses. Therefore, in order to ensure safety and resistance to infection, the residual blood sample must be sterilized after the blood test is completed.
