Answer

Anemia due to deficiency in iron, folate, and, rarely, vitamin B-12 might be present. A low serum iron level is common. A systematic review of 18 studies comprising 2,998 patients with iron-deficiency anemia found that the prevalence of biopsy-confirmed celiac disease in these patients was about 1 in 31. [59]

The prothrombin time (PT) might be prolonged and the international normalized ratio (INR) may be elevated because of malabsorption of vitamin K.
