What is the toxoplasma IgG and IgM antibody test?

Igg will also appear and usually stay for life, suggesting you overcame the creatures. However, they may still be alive and dormant, to re-emerge should you become immunocompromised. ...Read more

IgG means old infxn: Igg is a measure of prior infection - so the elevated igg levels are to be expected. As long as the igm is negative (which indicates current/active infection), you have cleared the infection from 2 months ago. Your igg levels will always be elevated going forward. Make sure you ask your physician to clarify the labs - they know you the best. ...Read more

Likely protected: In acute infection, igm is initially elevated alone, and then igg is positive within a couple of weeks. Igg remains positive for your lifetime, but igm can persist for months to years. I would say that this new pregnancy is protected, but given the outcome of your prior pregnancy, you must discuss this in consult with a high-risk OB to confirm what I am saying! ...Read more

Currently 8 weeks pregnant with Toxsoplasma values IGG 90 (Positive) and IGM 1.54 (positive). Had an history of toxoplasma @ 2008, should we continue?

Discuss with OB: You need to discuss this with your OB, with probably a referral to a Maternal Fetal specialist to discuss the risk. A weekly positive IgM is possible from a prior exposure and not from a recent infection. Your MD may want to follow titers to see if they are changing. The IgG titer reflects antibodies you have from the prior infection in 2009. ...Read more

Toxoplasmosis: Misinterpreting a positive IgM can be minimized with confirmatory testing. Despite the wide distribution of commercial test kits to measure IgM antibodies, these kits often have low specificity and the reported results are frequently misinterpreted. In addition, IgM antibodies can persist for months to more than one year. The test used and the lab may influence results. ...Read more
