Overview of vitamin D testing
- Blood tests for just vitamin D cost from $50 to over $100
- Cost of vitamin D measurement might be lower if made with other blood tests
- Several governments are no longer permitting free vitamin D tests
- Test is typically performed at a testing lab, but several companies sell tests you can do at home
- Test results are often available in less than 3 days
- Test results typically have a reliability/repeatability/consistency of plus or minus 5 percent
- Example: 30 ng it could really be 28.5 ng to 31.5 ng
- The primary purpose of the blood test is to make sure you are getting enough vitamin D
- Rarely will the test show that you are not getting too much vitamin D
- You may want to have a loading dose and followed by 3 months on maintenace dose then get a vitamin D test to confirm that you are taking enough
April 2012 Costs of vitamin D tests are dropping $46

As of 2010 and 2011 many governments are no longer permitting free vitamin D testing unless you already have broken bones, etc.
The number of people and doctors requesting tests had increased 10X since year 2000 and the costs were getting too high
Suspect that the costs of not adding vitamin D exceed the costs saved by not testing.
