Does anyone know anything about a low platelet count? Basically my son who is 4 has autism, we went to rainbow house yesterday for blood tests which in our area is the hospital that deals with childhood disabilities. The blood tests were taken due to my son being very pale/ tired over the last few weeks and they added in genetic testing at the same time which is why it was this hospital originally for the test. Anyway that was 11am yesterday. 5:30pm yesterday I then got a phone call from the main hospital in our area who had said the lab had called them with my sons results and the doctor said he had severely low platelets and had to go in for another blood test. Took him up for it and came home, an hour later I got a call to say the test didn’t work and to take him in this morning for another test. We’ve just got home and said we’d be phoned with the results. I know absolutely nothing about platelets and Google isn’t much help, it’s just worrying me that we had to take him to hospital the same day of the result? My son is still very much fatigued all day, he bruises easily and just not been himself for a while. What could this be? I’ve been given no information at all apart from his platelet and red cell count being low.
