Blood test

Hi I am new to the forum, I have just recevided  letter in the post this morning asking for me to go to my GP for blood test right away. I went to my colposcopy appointmemy just three days ago. 

I wasnt expecting to hear anything back That quick. Has anyone experienced this or know what the blood test could before? 



I've had something similar. I had my 6 mth follow up smear(post leetz)  6 weeks ago. I'm still waiting for the results, :( but I had a letter from my Gp requesting I go in for blood tests. Does anyone know if this is related? Does it mean the worst?
