Two days later I took my son in for another CBC and his count was down to 11,000. The hematologist asked that I bring my son back three days later to get his count again. Only 4,000 at that time so we decided to have another round of IVIG. My hematologist mentioned that sometimes it can take up to 3 tries of IVIG until the body responds.
Two days later his petechiae has faded and his platelets are at 50,000! We are praying that the second IVIG did the trick and that his body will take over after the IVIG wares off in several weeks. Hopefully this is an acute case.
Will up date after my appt next week with the hematologist.
