Vitamin Toxicity Differential Diagnoses

  • Author: Mark Rosenbloom, MD, MBA; Chief Editor: Asim Tarabar, MD  more...
 
Updated: Dec 05, 2015
 
 

Diagnostic Considerations

Differential diagnosis in vitamin toxicity can include the following:

  • Ciguatera toxicity
  • Fluoride toxicity
  • Iron toxicity
  • Osgood-Schlatter disease

Vitamin E

An elevated international normalized ratio (INR) may result from excessive doses of warfarin anticoagulants. Vitamin K deficiency and liver failure can prolong the prothrombin time (PT) and raise the INR.

Vitamin A

The skin pigmentation seen in carotenemia is also observed with the consumption of large amounts of colored fruits and vegetables.
