The TORCH Panel - IgG test is your "immunity check." It measures the long-term "memory" (IgG) antibodies for the full range of TORCH infections. A positive IgG result is good—it means you are immune, either from a past infection or vaccination (like for Rubella). This is a critical, foundational part of pre-pregnancy planning, as it confirms you are protected. This test is a key component of our complete TORCH Profile, giving you a clear picture of your long-term immunity.
