GENERAL INFORMATION
Expected TAT 2-5 Days  
Clinical Use If a newborn child has a significantly low platelet count and the physician suspects neonatal alloimmune thrombocytopenia purpura (NAIT), a serum platelet antibody test should be ordered on both the mother and the child (patient). The work up for NAIT is best accomplished by not only evaluation for platelet reactive antibodies but also typing maternal and paternal platelet glycoproteins.
