Vitamin D (25-Hydroxy) Test: What It Measures and Why It Matters

The 25-hydroxy vitamin D test is the best way to measure your body’s vitamin D stores.

What the Vitamin D test measures

Why we check it at Serene

Vitamin D supports bone strength, muscle function and immune health, and low levels are common, especially in the winter months. Low vitamin D can add to fatigue and weakness, and it matters for bone health alongside hormones.

At Serene Med Spa in Hudson, Ohio, every hormone and wellness plan starts with Labcorp lab work reviewed by a board-certified physician.

What your results can mean

Higher than normal

High levels are almost always from taking too much supplement and can be harmful, so doses should be guided by testing.

Lower than normal

Low levels are common in people who get little sun, have darker skin, carry extra weight, have digestive, kidney or liver disease, or have had weight-loss surgery.

Normal ranges vary by lab, age and sex. Your physician reads every result together with your symptoms, history and other tests.

How to prepare

No fasting is needed. Tell us if you take vitamin D supplements.
