Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is one of the most important causes of thrombocytopenia in otherwise healthy, term-born infants [1]. During fetal life, the fetal platelet count rapidly increases and reaches a constant normal level, equal to adults, by the end of the first trimester. Therefore, the definition of a normal platelet count and thrombocytopenia in fetuses and neonates is equal to adults. Normal platelet counts range from 150–450 × 109/L and a (fetal or neonatal) platelet count below the 5th percentile, 150×109/L, is defined as thrombocytopenia [2]. Further classification into different degrees of thrombocytopenia can be made into mild (100–150 × 109/L), moderate (50–100 × 109/L), severe (<50 × 109/L), and very severe thrombocytopenia (<20–30 × 109/L).
