What is a serological study?
A serological study consists of analyzing the blood to detect and measure the amount of antibodies against a possible exposure to a virus or microorganism. This type of study does not require any prior preparation by the patient.
IgM antibodies or immunoglobulins are the first antibodies or immunoglobulins produced by the body when there is contact with an infectious agent. On the other hand, IgG usually indicates that the infection has already been overcome and there is protection against that virus or microorganism.
