Question 1

does igg and igm indicate if a person is being tested for a herpes zoster infection?

Accepted Answer

Not sure: of your question. If Igg zoster antibodies are low, there may not be immunity; if Igm is high, it is an indication of acute infection. So if these tests are being run, that is why.

Question 2

antibodies for varicella zoster igg positive, and varicella igm negative, means immunity for shingles or just for chicken pox?

Accepted Answer

Both: Varicella and zoster are the same virus. Chickenpox occurs with the first exposure to the virus and zoster is the re-activation of the virus that has been lying dormant in the body as a result of some significant stress to the body.

Question 3

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 4

what does anti hbcag-igm non reactive means?

Accepted Answer

Negative: It means you do not have an acute (or recent) infection of hepatitis b virus.

Question 5

what is  a large amount of  igm in your blood

Accepted Answer

Its an antibody.: Antibody types in your blood include igg, IgA and igm.  When there is a generalized increase in antibodies, which can happen with inflammation, it's call "polyclonal."  if there is a single antibody molecule that is increased, it's "monoclonal".  That can be either benign (monoclonal gammopathy of undetermined significance) or a sign of cancer, usually a lymphoma, diagnosed by bone marrow biopsy.

Question 6

what does it mean if igm and iga levels drop lower?

Accepted Answer

IgM and IgA: Low levels of IgA and IgM may mean that you have an immune deficiency.  If they are only slightly low and your igg is normal and you are able to respond to vaccines and do not have a lot of infections, there may be nothing to worry about.  We need a lot of history and additional blood tests to understand what any particular level of antibodies in the blood means.

Question 7

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 8

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 9

how dangerous can an elevated igm level in a 4 year old be?

Accepted Answer

It depends: It depends on how high the level is.  Normal igm levels vary depending on age.  A high igm level at one age may be normal at another age.  If the level is borderline elevated i would not be concerned. If it is 5 times the upper limit of normal then i would go to a hematologist.

Question 10

what do you recommend if i have elevated igm levels in a 4 year old?

Accepted Answer

IgM levels: Elevated IgM levels to what?? Igm elevation usually means an active infection or a recent immunization. These levels are specific, though. For instance, if you contracted measles, the IgM level to measles rises over the first few weeks, and then usually disappears by 6-8 weeks after illness. So if child had shots or was recently sick, I'd want to see IgM levels rise for that specifically
