Every animal is unique. As such, even if they are eating a “complete and balanced” diet, there is still potential they are short on one or more essential vitamins.  Testing is simple and cost effective using the VDI Essential Vitamins test.  This blood test checks Vitamin D, Vitamin B12, Folate, and Magnesium levels.  

A blood sample from the patient is applied to a device and simply mailed by common carrier. The device easily crosses international borders without custom declarations. Dosing information is provided on the report detailing the results and patient-specific dosing required for the cat or dog, along with recommended supplements that can be found at such as RX D3 & RX B12.

Directions for The Pet Owner:

  • Take this kit (unopened) to your veterinarian with your pet
  • Give to vet staff & discuss the need for a serum blood draw
  • Provide contact information to vet staff
  • Don't worry, there are directions & information on the included card that direct veterinary staff as to the next steps!

*Not an at-home test.  Requires a serum blood draw from a vet clinic.

*Fasting recommended (8 hours)
