How to Interpret 25 OH D3 Test Results

25 OH D3, also called Calcidiol or 25-hydroxyvitamin D3, is the primary form of vitamin D found in your blood. This test measures and calculates the concentration of 25 OH D3 in your body. The results are then used to determine if you have a deficiency or sufficiency in vitamin D.

Why should you take a 25 OH D3 test?

Vitamin D plays an essential role in maintaining healthy bones and teeth by regulating calcium absorption. A lack of vitamin D can lead to various health problems such as osteoporosis, rickets, and even cancer.

What are the possible levels for my results?

According to most laboratories, here are the possible interpretations according to ng/mL:

  • Less than 10 ng/mL: Severe deficiency
  • Between 10-20 ng/mL: Mild deficiency
  • Between 20-30 ng/mL: Insufficient levels
  • Between 30-100 ng/mL: Optimal levels
  • Above 100 n/mL: Excessive levels

These numbers may vary depending on where you live or what laboratory processed your sample.

I have low vitamin D levels; how do I increase it?

There are two primary ways people can increase their vitamin-D intake; either through sunlight exposure or diet/supplementation.

Sunshine has long been known as the most straightforward way of increasing Vitamin-D production naturally. This is because when exposed to UVB light from direct sunlight rays within specified hours daily over some time increases chemical conversion that produces Vitamin-D.

Also beneficial will be incorporating foods rich with Vitamin-Ds like fish oil/oily fish , mushrooms and milk/fortified products into one’s regular diet.

Supplements may also help boost vitamin-d concentrations although professional consultation before taking any supplements is advised.

Is there such a thing as having too much Vitamin-D?
