Hi,
I am currently travelling abroad till the 12 of Jan. Yesterday, I tested because I have a yellow fever vaccine booked for tomorrow and surprise! It was positive. Today I did a second and I got the same result. Obviously I am not going to do the vaccine and I'll contact my GP to understand what the next steps are. Meanwhile is there any possibility that tests are false positive? I have pcos and endometriosis. Should I do a blood test?
