Understanding your Vitamin D Rapid Test results
To help you understand what steps to take once you have received your results, we’ve put together this page to help you interpret what your results may mean and what you may want to do with these results. Remember: you should always consult a medical professional before making changes to your diet and lifestyle.
Before you continue its important that you have:
- Read the ‘instructions for use’ leaflet included in your kit
- Taken the test according to instructions
- You have interpreted your results against the colour card provided
Interpreting your results
Once you have collected your sample and performed your test, you must wait 10 minutes after applying your sample into the test cassette, before you read the results. From there, it’s essential that you compare the test (T) line , intensity with the “vitamin D colour card” provided with the kit to get an indication of the vitamin D level in your blood. Do not interpret the result after 20 minutes.
