In what way you can determine if a baby has toxoplasmosis?

Blood tests: Diagnosis can be confirmed by detecting a positive blood test called the IgM assay for toxo in the first 6 months. An IgG assay may pick up moms transferred material and would not be specific for baby.The IgM would be produced by the baby in response to an infection. Suspicion & need for testing may arise from exam findings.

Blood Test: Serology(igm, igg antibodies) , polymerase chain reaction assays(pcr), histopathology.
