Monitoring

Patients should be instructed about the need for monitoring the neonate and infant for signs and symptoms of anaemia. Infants affected by Rh incompatibility, even those successfully treated in utero, may develop late anaemia commencing 1 week to 3 months after birth, due to the continued presence of circulating antibody-coated fetal red blood cells that continue to be haemolysed. The importance of neonatal follow-up cannot be overemphasised, with assessments of the infant's haemoglobin once or twice a week until 3 months of life.[63]
