Patient's question:
NoDoctor's answer:
If a child has low platelet counts from birth, it may be related to platelet antibodies, but if the symptoms are severe at birth, it doesn't seem like the case based on your description. If the child's platelet counts dropped after exposure to blue light, it might be related to the blue light exposure. As long as the child is not bleeding, it is not serious. Platelets are constantly regenerating and have a certain lifespan, so once the antibodies from the mother are gone and blue light exposure stops, the platelet counts should recover with the regeneration of new platelets. It could also be another condition, such as an autoimmune or infectious disease, and further specific tests are needed.
