Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare immune disorder. FNAIT occurs when the baby’s platelets are attacked and destroyed by the mother’s immune cells in her blood stream. It is estimated that FNAIT can occur every 1 in 1,000 live births. This immune response can develop when the mother’s blood is exposed to her baby’s blood, either during development of the fetus in the womb or when the baby is being born. FNAIT can occur in a woman’s first pregnancy and/or in subsequent pregnancies.
