What is implication homogeneous ANA 1:320, compliment 4 high 44, sed rate and c-reactive protein often elevated and vitamin d low?

Several causes. The vitamin d is probably a seperate problem and should be treated by a supplement. The other lab you reported can be a sign of an autoimmune disease as well as many other diseases. You should discuss the cause with your doctor.
Possible autoimmune. Ana+ with high ESR and CRP can mean lupus or other autoimmune disease. Vit d is unrelated and should be replaced with supplements. High c 4 is not a problem.
