Question 1

what does a low igm mean?

Accepted Answer

IGM: IGM = Immunoglobulin M. Your body makes IgM antibodies when you first get infected with some sort of germ. It helps to protect you but then the levels will drop off.

Question 2

what does an igm count of 414 mean?

Accepted Answer

IgM: IgM is an antibody that is produced in response, such as to an infection, with subsequent switching to a more customized antibody such as IgG antibody (usually at day 7 to 10 after exposure).  Hence, IgM usually reflects lack of memory to an antigen and is a sign of an acute infection.  There are extremely rare conditions associated with elevated IgM but usually occur early in life.

Question 3

what do elevated levels of igm mean?

Accepted Answer

Depends: The "normal ranges" for all lab tests include 95% of the "normal" population; thus, 2.5% of people are above the upper limit, and 2.5% are below the lower limit. There's nothing to worry about if your values are a little bit above the normal range, but a very elevated IgM could be a sign of a problem. You need to check with the physician who ordered the tests to interpret your results.

Question 4

when should a igg vs a igm test be ordered?

Accepted Answer

IgM vs. IgG: Igm tests are typically ordered when an infection is thought to be present for one week or more. Igm levels often disappear within the first few months. Igg testing is typically ordered when the infection has been thought to be present for 2 or more weeks. Igg levels my stay elevated for years after an infection has resolved.

Question 5

what is the function of the extra domain in ige & igm?

Accepted Answer

Trick question: Are you studying immunology? The extra domain on ige  indicates a unique role for the C2 domain in the interaction between ige and fcri. C2 reduces the off-rate of the ige/fcri, thereby resulting in a more stable complex. It is felt that the domain on igm co-contributes to the pentamic structure production.

Question 6

my antirubella igg >400 and igm 0.91.what does it mean?

Accepted Answer

Rubella: IgG is Immune so you have immunity to Rubella.  Don't worry about the IgM.

Question 7

what are torch igg and igm tests used for?

Accepted Answer

Immune system: Igg are igm are different types of antibodies. Low levels are associated with a risk of infection. High levels can be a sign of infection or other disease.

Question 8

what causes high igg antibodies but negative igm?

Accepted Answer

Immunity: Igm is the first line of defense and reacts first, then long term immunity is provided by igg. So a positive igg and negative igm to something means an old exposure.

Question 9

what is torch test? what does igg and igm test mean?

Accepted Answer

Infectious Diseases: Torchs tests for various unusual disease such as toxoplasmosis, other, rubella, cytomegalovirus, herpes, syphilis. Mowt persons do not get these diseases but if they do-they may endanger the fetus. Ob's always test for immunity to rubella and the test for syphilis is always done. Igg is an antibody that shows that the person was exposed at one time. Igm looks for a recent infection.

Question 10

if my wife is vaccinated with rubella, why igm positive?

Accepted Answer

Should be positive: Igm is the immunoglobulin noted for coming out early in response to any illness or vaccine, it fades over time while igg come out a bit later and stays up longer. If your wife had a rubella vaccine a positive IgM indicates she had a good response to the vaccine and future pregnancies will not be at risk.
