Yes, there are advanced blood tests that can be done as well as an Covid antibodies test. I got sick 17 months ago & have been treated all this time for food poisoning which ultimately caused nausea, gerd, & gastroparesis. My swab tests were negative, I had no lung issues, no cough, no fever so the 4 diff DRs I saw (& 3 ER visits) never connected the dots!!!

Last month…I found a DR who is specializing in Long-Haul Covid symptoms. She ordered 11 blood tests & 6 came back ‘abnormal!’ My immune system is totally tanked.

She was able to confirm that I have Long-Haul since my Covid antibodies are still at 5619. Apparently, 5000-20,000 is considered high. Who knows how high they were 17 months ago!

There’s just so much Providers don’t know just yet & personally I’m ready to stop being a Guinea pig!!!
