The difference between igm and igg

If the body is found to have igm through examination, it means that the body has been infected by the virus. However, there is no need to worry too much, because this situation also shows that there are certain antibodies in the body. If igg is found after physical examination, it means that the virus has appeared in the body and the virus has been replicating. This requires timely treatment. Let us take a detailed look at the difference between igm and igg.

First, the difference between igm and igg. IgG antibodies are the smallest type of antibodies and can be transferred to the fetus through the placenta, protecting the baby from infection during the first six months. This antibody is produced late, lasts long, disappears slowly, and has high concentration. Detection in the blood can serve as an indicator of long-term infection. IgM antibody has the largest molecular weight among antibodies and cannot be transferred to the fetus through the placenta. Antibodies are produced the earliest and are produced rapidly once infection occurs, playing an anti-infection role in the early stages of infection. But it lasts for a short time and disappears quickly.

Second, primates have four main immunoglobulins: IgG, IgM, IgA, and IgE. All immunological methods used to detect antigens can be used for antibody detection after appropriate modification, such as IFA, ELISA, RIA, LA... Due to the increased sensitivity of antigen methods and the application of PCR technology, the heterogeneity and instability of HSV antibodies in HSV-infected individuals have affected the significance of such indicators in clinical diagnosis. However, as an infection-related indicator, it is still necessary to conduct detection and in-depth research within a certain range and under certain circumstances. Currently, there are three main types of HSV-specific antibody detection: IgG, IgM and IgA.

Many people tested positive for IGM in their first blood test, but when they went to another hospital for a second test, the result had turned negative. So if you encounter a virus-positive situation, don’t be nervous, because even if you have the virus in your body, it will not necessarily be transmitted to the fetus. The probability of intrauterine infection is still relatively low! The baby himself will also have resistance.
