The preoperative quadruple test will usually produce results if there is a problem. The preoperative quadruple test includes Hepatitis B penta (or surface antigen only), Hepatitis C, Syphilis, and HIV. Commonly known as the infectious disease series, by perfecting the test, can maximize the doctor in the operation, because of ignorance and unnecessary harm, in the postoperative period can also be clear in the fever with or without the factors of the above diseases. The results of the four preoperative tests will come out, regardless of whether there is a problem or not, and the results must be reported before the surgery. If there is a problem with the results of the tests, the results must also be produced so that the doctor is aware of the results and to avoid the negative consequences of an injury resulting in an infection. It is only used for emergency life-saving surgery when it is not clear whether the person being examined has an infectious disease or not, and the medical staff must be careful when handling it to avoid injuries.
