Not all infectious diseases can be detected through blood tests; different testing methods should be chosen depending on the type of disease.
Syphilis, HIV, hepatitis B, and hepatitis C can be detected through blood tests. Patients can go to a reputable hospital for testing. Blood tests and complete blood counts can determine whether an infectious disease is present in the body. Gonorrhea, chlamydia, genital warts, and mycoplasma require tests of local secretions and are generally not detectable through blood tests. Therefore, the testing method for infectious diseases must be analyzed specifically based on the patient's disease type.
In daily life, if there are people with infectious diseases around you, try to avoid direct or indirect contact with them to prevent infection and the spread of the virus. At the same time, if you have an infectious disease, try to self-isolate and avoid going to crowded public places.
