Vitamin D Test Kit for Dogs and Cats

Vitamin D is not manufactured in the skin of dogs and cats, as it is in human beings. They get all of their vitamin D from their food, or from dietary supplements.

In studies it has been found that most dogs and cats have insufficent levels of vitamin D in their blood.
Insufficient doesn't mean deficiency. A vitamin D deficiency will cause Rickets which is associated with bony deformities.
Insufficiencies of Vitamin D has been associated with a number of serious diseases in dogs and cats,
such as many types of cancer, inflammatory bowel disease, heart disease, kidney disease, inflammatory hepatitis, auto-immune disease,  and even feline oral resorptive lesions (FORLS)

By determining your pet's baseline Vitamin D it allows us to administer a safe and effective amount of vitamin D3 as found in the product by RxVitamins, RxD3 for dogs and cats.

You can very simply place the tasteless drops of vitamin D in olive oil onto your pet's meal and they will never know that you taking care of their health preventatively and easily.

If you are feeding a home made diet, this test is ideal for determining how much vitamin D to give your pet.

If you change your pet's diet, or add dietary supplements that contain vitamin D, such as cod liver oil with naturally occuring vitamin D, you will have to retest its vitamin D levels to be sure you are giving it enough, and not too much.

How to do it: Take the test kit to your veterinarian who will draw a blood sample from your pet. They will clot the blood and spin it to get the serum.

Have the veterinarian follow the instructions in the kit. They will need 1 ml of serum for the test preferentially, but if only 1/2 ml of serum is collected that can also be used. The pipet included in the kit will allow the veterinarian to draw up enough serum to fill one of the two wells. If there is enough serum they can fill the second well also. Several other tests are available from this test kit from VDI Laboratories, including a canine C reactive protein and calcium, but these will need to be requested from VDILabs and paid for through their website or customer service telephone line ( and 805 577 6742) 

Your veterinarian can view the instructional video on YouTube if they follow this link:

In 10-12 weeks following the first Vitamin D test  you will need to recheck the vitamin D levels to insure that your pet has reached a level of sufficient vitamin D to protect their health. If there are changes in supplements that add more vitamin D to your pets daily amount, or a diet change, you will need to redo the test in order to readjust the daily dosage you are giving.
