TORCH is a group of infections. If any of these infections are acquired in pregnancy
(especially in the first trimester of pregnancy), they can result in congenital malformations in the baby.
Your report - a positive IgG
with a negative IgM - suggests that you may have been exposed to these infections sometime in the past. It does not indicate recent infection. It is unlikely that your recent abortion
was due to any of these infections.
Hope this helps.
