A positive blood test is an indication that an abnormal result may have occurred in the blood test in question. A positive blood test result is comparable to a negative result, and is a qualitative judgment indicating that there may be an abnormality in the test, which needs to be analyzed depending on the specific test. For example, in hepatitis B penta test, syphilis test, AIDS test and other infectious diseases test, the blood positive represents that the patient may be infected with the relevant germs or viruses, and may show some uncomfortable symptoms as well as the corresponding systemic clinical symptoms. For people with positive blood should go to the hospital in time for diagnosis and treatment, according to the specific test indicators, to choose the appropriate treatment program for treatment and improve the prognosis.
