Option 1 : I am not sure if CVs know it or not, in reality, a person who has low hb count, cannot donate blood, and there is no need of a medical report and a day to tell the donor that her blood count is less. So, I feel they have changed the script after viewers spamming them for no ishra separation.
Option 2 : I feel Ishita would have requested the doctor not to disclose anything incase if there is any seriousness in her report in front of Raman seeing Raman's state of fear after the dream.
I seriously hope it is first option though somewhere I have fear that it could be second one
