Generally Bilirubin levels are not associated with Vitamin D and Vitamin B levels apart from new borns / infants. While your Vitamin D levels are within normal range, Bilirubin is slightly elevated. This can be due to some recent infection, excessive alcohol intake or gall stones. While this condition usually resolves on its own, I suggest you get an ultrasound abdomen done to rule out any liver disease. Also avoid alcohol and fried/spicy foods for a while. Repeat LFT after 2 weeks if no symptoms or after 1 week if you get any symptoms like pain in the abdomen or indigestion or nausea
