Thanks for your advice Hopeful, it is a mental adjustment to not 'freak out' at such levels
We are all just a bit cautious about platelets I guess because my sister sustained retinal haemorrhaging which lead to pretty serious visual impairment after contracting a vomiting bug all those years ago. Being a child at the time too I am not even sure what her levels were to compare to now... No one knew to keep her in an isolation ward back then either..
I didn't know about the refractory issue so thank you for letting me know about that too
