Seronegativität

Seronegativität refers to the absence of antibodies against a specific antigen in a person's blood. This term is commonly used in medical and scientific contexts, particularly in the diagnosis of infectious diseases. The absence of antibodies indicates that the person has not been exposed to or has not developed an immune response to the particular pathogen. For example, in the context of HIV testing, a seronegative result means that the person does not have detectable antibodies against HIV, suggesting that the person is not infected with the virus. However, it is important to note that a seronegative result does not provide a definitive diagnosis of absence of infection, as it may take several weeks for antibodies to develop after initial exposure to a pathogen. Therefore, seronegativität is often used in conjunction with other diagnostic tests and clinical evaluations to determine the presence or absence of infection.
