Routine DMT blood test - unsure if flu jab timing could interfere with results!

Hi there,

Has anyone had any advice from MS nurses etc about if you need to watch out for anything when booking your routine yearly blood test (to check if your immune system is okay with DMT)?

I want to make sure my COVID/flu jabs don’t interfere with results, and don’t know if I need to make sure my actual DMT (Kesimpta) also doesn’t interfere with the results!

Have sent this question along to my MS team, but wondered if anyone had been in the same boat?

MS nurses recommended that I got the blood test before my COVID/flu jab, but said it didn’t matter if took Kesimpta (my DMT) before.

It didn’t sound like it massively matters however, but just for safety, better to not have the flu/COVID jab right before
