Is it possible to get a negative ANA test because of not being in an active flare? I always have low grade symptoms like a fever and fatigue but I think I've recently discovered that the sun triggers severe flares (significant weakness like I can barely stand for a few minutes, shortness of breath, tightness in my chest, extreme exhaustion like I can sleep for 3 days through my flares, sometimes I have joint pain but it depends, and the main attraction: the horribly debilitating migraine that pulses and every time it pulses it then goes through my whole body). I've had various rashes, that was one of my earliest symptoms, a bright rash that looked like my skin was swollen all over my face after an outdoor unit in the winter in my senior year of school. I've had an ANA test shortly after I started getting sick in 2020 but im wondering if it's possible it was either too early or if I wasn't in an active significant flare if it didn't show up properly?
