Repeated freeze/thaw cycles can denature an antibody, causing it to form aggregates that reduce the antibody's binding capacity.
CMV AB IGM refers to the presence of IgM antibodies against cytomegalovirus (CMV). IgM antibodies are produced early in the immune response to a current or recent CMV infection. Detection of CMV IgM antibodies can aid in diagnosing an active CMV infection.
That you have an acute Rubella infection and have developed IgM antibodies.
IgM IgG
IgM is produced upon initial exposure to an antigen. For example, when a person receives the first tetanus vaccination, antitetanus antibodies of the IgM class are produced 10 to 14 days later. IgM is abundant in the blood.
The presence of IgM antibodies indicate acute infection, mostly from Parvovirus and Rubella in babies.

antibodies against dengue virus which appear in the body in response to infection after Ig M antibodies
Some examples of antibodies include IgA, IgM, IgG, and IgE. Antibodies are a form of proteins that make up the immune system of the body.
There are five immunoglobulin classes (isotypes) of antibody molecules found in serum: IgG, IgM, IgA, IgE, and IgD. IgA (immunoglobulin A) IgD (immunoglobulin D) IgE (immunoglobulin E) IgG (immunoglobulin G) IgM (immunoglobulin M)
The ELISA test for IgM and IgA is a laboratory technique used to detect the presence of immunoglobulin M (IgM) and immunoglobulin A (IgA) antibodies in a patient's serum. IgM antibodies are typically produced early in an immune response, indicating a recent infection, while IgA antibodies are primarily found in mucosal areas and indicate local immune responses. This test is often used in diagnosing infections or autoimmune diseases, providing valuable information about the patient's immune status.
It's a test of antibodies, often to determine if infection is recent. For instance, Varicella IgM will give you a hint if the patient recently had chicken pox.
The varicella-zoster virus (VZV), which causes chickenpox and shingles, is primarily targeted by IgM antibodies during the initial immune response to an acute infection. IgM antibodies are produced shortly after the onset of infection and indicate recent exposure to the virus. Their presence can be used to help diagnose active varicella or shingles. However, IgG antibodies are typically measured to indicate past infection or immunity.
