IgG tests and chlamydia?

Question

in my health class i learned that IgG tests are different from IgM tests (or something like that) in that the IgG tests for past exposure and the other tests for the actual presence of the infection being tested for (chlamydia). if an IgG test comes up positive can someone have had exposure to chlamydia without actually contracting it? i also learned that it is about 60% effective in comparison to a vaginal probe or urine test at 90-98% effective. if anyone has insight let me know with as much detail/information as possible

Answer 1

Yes, IgG denotes past infection, IgM denotes current infection.

In the case of chlamydia, you can be exposed to the bacteria, develop immune response to it, but never actually get sick. This is the basis for an infectious dose -- enough pathogen needs to be present to cause illness. anything less just gets squelched by your body's defenses.

Your use of the word "effective" is inappropriate here, but I get your point. You meant to say ACCURATE, which is a measure of how true a result it. A positive IgG is prone to false positives because past exposure does not necessitate past infection. Moreover, infection with or exposure to similar bacteria in the past can result in cross reactivity in the immune assay. IgG may be a very reliable test, but its accuracy is only 60%.

beside, IIRC, the test for clamydia (and gonorrhea) is a culture, not an immunoblot.

Answer 2

IgM and IgG are aspects of your immune gadget universal as immune globulins. customarily, your body will produce IgM first, in the course of the "acute" (it really is, lively) area of the an infection. IgG is produced later and lasts longer. So, in case you've been those days dealt with, that is smart that your IgG degrees are nonetheless severe. in the journey that your IgM is now unfavorable, try to be superb. yet possibly you ought to make sparkling this with the well being care specialist who did the attempt - i imagine it is going to positioned your ideas comfy to finish that.
