A member asked:

On an igg blood test does that determine the time frame of when i would have gotten it ? if i have it now and its at a low value does that mean its been around for some time ?

The IgG means you had whatever you are testing at some point in the past but it does not indicate when you had the infection (if an infection is what is being measured). A positive IgM would mean it is more recent. Good luck!!
