VITAMIN D, 25 Hydroxy

Description

The Vitamin D, 25 Hydroxy (25-OH Vitamin D) test measures the level of 25-hydroxyvitamin D in your pet’s blood — the most reliable indicator of your dog or cat’s overall vitamin D status. Vitamin D plays a critical role in calcium and phosphorus regulation, bone health, immune function, and muscle performance in pets. This test is available with convenient at-home sample collection in Hyderabad.

What Is the Vitamin D, 25 Hydroxy Test?

Unlike in humans, dogs and cats cannot synthesise adequate vitamin D through sun exposure alone — they rely almost entirely on dietary intake. The 25-hydroxyvitamin D test measures the storage form of vitamin D in the bloodstream, giving your veterinarian a clear picture of whether your pet has optimal, deficient, or toxic levels of this essential nutrient.

When Is This Test Recommended for Pets?

Your veterinarian may recommend a Vitamin D, 25 Hydroxy test for:

• Investigating bone disorders such as rickets, osteomalacia, or unexplained fractures
• Evaluating muscle weakness, stiffness, or generalised lethargy
• Pets with chronic gastrointestinal disease (IBD, EPI, malabsorption) that may impair vitamin D absorption
• Monitoring pets on vitamin D supplementation to check for toxicity or under-dosing
• Investigating suspected vitamin D toxicity — which can cause life-threatening hypercalcaemia in dogs
• Pets fed home-cooked or raw diets that may be nutritionally incomplete
• Routine nutritional screening for senior pets or those with chronic illness
• Supporting management of immune-mediated diseases or chronic infections, as vitamin D plays a key role in immune regulation

Signs That May Indicate Vitamin D Deficiency or Toxicity in Pets

• Deficiency: Bone pain or deformity, muscle weakness, poor growth in young animals, dental abnormalities, immune suppression
• Toxicity: Vomiting, lethargy, loss of appetite, excessive thirst and urination, weakness, kidney failure — can be caused by accidental ingestion of vitamin D-containing rodenticides or supplements

What Does the Test Measure?

• Serum 25-hydroxyvitamin D (25-OH Vitamin D) concentration
• Reflects total body vitamin D stores from both dietary intake and supplementation
• Helps differentiate between deficiency, sufficiency, and toxicity
• May be used alongside calcium, phosphorus, and PTH (parathyroid hormone) levels for a complete mineral metabolism panel

Sample Type & Preparation

• Sample type: Serum (routine blood draw)
• Fasting: Generally not required, but your vet may advise it for combined panels
• Special notes: Inform your vet of any vitamin D or calcium supplements your pet is currently receiving
