Final answer:
The TORCH IgM and IgG assay does not include detection of antibodies for Infectious Mononucleosis. Instead, the detection of "heterophile" antibodies is used to diagnose this condition, which is primarily associated with the Epstein-Barr Virus (EBV).
Step-by-step explanation:
The TORCH immunoglobulin M (IgM) and IgG assay is a diagnostic panel used to detect antibodies in the blood that may indicate infection by a group of pathogens known to cause congenital infections. These pathogens typically include Toxoplasma gondii, Rubella, Cytomegalovirus (CMV), and Herpes Simplex Virus. The assay does not include detection of antibodies specific for Infectious Mononucleosis, which is commonly caused by the Epstein-Barr Virus (EBV). For Infectious Mononucleosis, the detection of "heterophile" antibodies is performed instead of the TORCH IgM and IgG assay. This specific test is used to detect the presence of the heterophile antibodies in a patient's serum, which are early indicators of the disease.
