I couldn’t go to the lab due to Covid19, so I did an at home/mail in test for RA through a company called ImAware. It came back with 234 u/ml for CCP IgG. I went to my doctors lab about a month later to get tested and my CCP IgG level was 0.5 u/ml, so negative. Both tests showed negative RF.
Is it possible for a test to be positive and then negative a month later? Is the first lab I used inaccurate? I’m so confused, has anyone else had this happen?
