Customer Reviews

What is the Vitamin D Test Kit Plus used for?

The Vitamin D Test Kit Plus is designed to measure 25-hydroxyvitamin D (25-OH Vitamin D) levels from a blood sample. It helps evaluate a pet's vitamin D status using laboratory analysis.

How does the Vitamin D Test Kit Plus work?

The kit includes the materials needed to collect and submit a blood sample for laboratory testing. Once the sample is analyzed, the results provide your pet's 25-OH Vitamin D level to help your veterinarian assess vitamin D status.

Why is measuring 25-OH Vitamin D important in pets?

25-OH Vitamin D is the primary marker used to evaluate vitamin D status. Measuring this level provides valuable diagnostic information that can assist veterinarians in assessing and monitoring a pet's nutritional and clinical needs.

Is the Vitamin D Test Kit Plus intended for at-home diagnosis?

No. The Vitamin D Test Kit Plus is designed for sample collection and laboratory analysis, with results intended to be interpreted by a veterinarian as part of a complete clinical evaluation.

How long does shipping take, and is shipping free?

Consumer orders ship free with no minimum purchase and typically arrive within 3–5 business days. Wholesale orders qualify for free shipping on purchases over $300. Tracking information is emailed as soon as your order ships, so you can follow its delivery progress.

Vitamin D Test Kit for Dogs and Cats

Rx Vitamins Vitamin D Test Kit PLUS+ is a canine and feline sample-collection kit used for laboratory measurement of 25-hydroxyvitamin D (25-OH Vitamin D). The kit is designed to help veterinarians evaluate a pet's vitamin D status as part of a broader clinical and nutritional assessment.

This is not an instant home diagnostic test. Samples are collected using the included materials, submitted for laboratory analysis, and the results are intended to be interpreted by a veterinarian.

Measures 25-OH Vitamin D

The Vitamin D Test Kit PLUS+ is designed to measure 25-hydroxyvitamin D, the primary laboratory marker used to evaluate vitamin D status.

Testing can provide useful information for veterinarians reviewing a dog's or cat's nutritional and clinical needs.

For Dogs and Cats

The Vitamin D Test Kit PLUS+ is intended for canine and feline patients.

It can be used as part of a veterinary wellness or nutritional assessment when vitamin D status needs to be reviewed.

Mail-In Laboratory Testing

The kit is designed for sample collection and laboratory submission rather than immediate at-home interpretation.

After the sample is prepared, the included preaddressed return envelope can be used to send the sample for laboratory analysis.

No refrigeration is required according to the current product instructions.

What Is Included in the Kit?

Each one-patient kit includes:

Spot Saver Card
Sample Transfer Pipette
Patient Information Card
Plastic Bag with desiccant
Preaddressed return envelope

Optional Testing Panels

The Vitamin D Test Kit PLUS+ also allows optional testing to be added through the laboratory.

Depending on the selected panel, additional tests may include:

Vitamin B12
Folate
Magnesium
Inflammation testing
Degenerative joint disease testing
Cancer risk assessment

Optional tests are selected on the requisition form and may be invoiced separately by the testing laboratory.

Essential Vitamins Panel

One available combination includes Vitamin D, Vitamin B12, folate, and magnesium.

This option allows multiple nutritional markers to be evaluated from a single testing workflow.

Essential Wellness Panel

The Essential Wellness Panel can include Vitamin D, Vitamin B12, magnesium, and inflammation testing.

This provides a broader laboratory view than Vitamin D testing alone.

Joint Health Panel

An optional Joint Health Panel can pair Vitamin D testing with degenerative joint disease testing.

This is an additional laboratory testing option rather than a diagnosis provided by the kit itself.

Full Wellness Panel for Dogs

A broader canine wellness panel may include Vitamin D, Vitamin B12, magnesium, inflammation, degenerative joint disease testing, and cancer risk assessment.

Optional panel availability and charges should be confirmed through the current requisition form and testing laboratory.

Is This an At-Home Vitamin D Test?

The kit can be used to collect and submit a sample, but it is not an instant at-home diagnostic test.

The sample must be analyzed by a laboratory, and results should be interpreted by a veterinarian as part of a complete clinical evaluation.

Why Test Vitamin D in Pets?

Measuring 25-OH Vitamin D allows a veterinarian to assess a pet's vitamin D status using laboratory data.

The result can help guide discussions about nutrition, supplementation, and follow-up testing when appropriate.

Vitamin D Testing and Supplementation

Vitamin D supplementation should not be started or adjusted based on guesswork.

Laboratory testing can help a veterinarian determine whether supplementation is appropriate and whether follow-up testing is needed.

Stratford also carries Rx Vitamins liquid Vitamin D3 products for dogs and cats, including standard and higher-concentration formulas intended for veterinarian-guided use.

One Patient Test per Kit

Each Vitamin D Test Kit PLUS+ is intended for one patient test.

Multiple-count options may also be available for veterinary practices that need testing kits for more than one patient.

Veterinary Interpretation Is Recommended

Vitamin D laboratory results should be reviewed in the context of the pet's health history, diet, medications, supplements, and other clinical information.

The test kit should not be used as a substitute for veterinary diagnosis or professional interpretation.

Rx Vitamins Vitamin D Test Kit PLUS+

Rx Vitamins Vitamin D Test Kit PLUS+ is a mail-in laboratory testing kit for dogs and cats designed to measure 25-hydroxyvitamin D and support veterinarian-guided assessment of vitamin D status.

The kit includes sample-collection and mailing materials and also allows optional laboratory panels to be added when broader testing is needed.
