I had a Hida scan to evaluate my gallbladder. The EF is 97%. What could cause an elevated EF of my gallbladder? I have suffered from symptoms of what my doctor thought might be lactose intoerance but I drink skim milk daily without problems. I am 30 years old and 5 4 and weight 145 pounds. I have no other significant past medical history.
