Ana titer of 1:320, psoriasis, raynauds, major fatigue, easily bruise, low platelet count, positive anticardiolipin iga level, neg igg & igm . what could it be?

You can have lupus, you have some symptoms, fatigue, low platelets, and Raynaud's phenomenon, and the high ANAs titer. The coexistence of Lupus and psoriasis is rare but not impossible.

I am thinking maybe 50 different things and not enough room to list them. Focus a bit an resubmit more information.

ANA of 320 is moderately elevated but nonspecific and has to be interpreted in the context of your clinical picture.. This is best done by a rheumatologist. Your RA can cause this degree of ANA elevation. You have an autoimmune disorder but the main issue here us whether you have Lupus. The rheumatologist will sort this out and may order further testing.
