Worried about Panorama results!!

Lucy
I took blood test on September 6th and I have been waiting since then for results. I thought I'd give it some time due to how long they told me it would take but I called the doctors office today and they told me the  test came back with "no result" and for me to go tomorrow for more blood for a retest. An hour later they called me back saying the doctor wanted to review the results with me at my appointment on Friday. Now I'm worried they are bad results!!
