Urgent ask for help. my moms d dimer value is 948. i am very concerned as she has received covid vaccine without having prior blood work done. she took it 2 weeks ago. pls suggest what further evaluation she needs. thank you so much?

We need to know what is normal D-Dimer for your lab. What made Drs order one in the first place. There is no reason to have bloodwork before vaccination unless something was going on.

Context is essential for isolated abnormal lab tests. Specifically symptoms and physical exam findings help in putting the puzzle together. While not likely, a connection between the vaccine and her D-dimer results cannot be ruled out.
