If IgG antibodies are positive, it indicates that the patient has been exposed to the pathogen at some point in the past and has developed an immune response. However, it does not confirm an active infection, as IgG can persist long after the initial infection has resolved. To determine if a patient is currently infected, additional testing for IgM antibodies or direct detection of the pathogen (e.g., PCR or culture) is necessary. This combination of tests helps differentiate between past exposure and active infection.

What does positive CMV Igg 28 mean?

A positive CMV IgG result indicates that a person has been infected with the cytomegalovirus (CMV) at some point in their life, and their immune system has produced antibodies against the virus. The "28" likely refers to a specific measurement or test value, but without additional context, it is difficult to interpret its significance. Generally, a positive IgG signifies past infection, while IgM antibodies would indicate a recent infection. It is important to consult a healthcare provider for personalized interpretation and implications.

What is positive CMV IGG?

Positive CMV IgG (cytomegalovirus immunoglobulin G) indicates that a person has been exposed to the cytomegalovirus at some point in their life and has developed antibodies against it. This is usually a sign of past infection and does not necessarily mean that the person is currently infected or experiencing symptoms. In healthy individuals, CMV typically causes mild or no symptoms, but it can be more serious in immunocompromised individuals or during pregnancy. Testing for CMV IgG is often done to assess immunity, especially in pregnant women or organ transplant recipients.


What can be confirmed by the rubella test?
