Francisco recently had his appendix removed and is now, once again, in severe pain in his abdominal region. His doctor thinks that a bacteria invaded during the surgery and was able to cause inflammation of the serosa around some abdominal organs. To confirm his diagnosis he orders what test listed below...
1) HCG level
2) Blood culture: we would find white blood (leukocytes) cells elevated
3) Lactate dehydrogenases (LDH)
4) Gastrin levels
