- Several governments no longer give free vitamin D tests
- Beware - hospital/govt tests often cost $150-$250
- Blood is typically drawn at a lab or hospital
- Low-cost Vitamin D testers (two yes-no tests for 11 dollars) - 2024
- Tests can also be made at home - blood spot is mailed in
- Test results from both are available in 1-5 days
- Test results from both 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 a blood test is to make sure you are getting enough vitamin D
- Rarely will the test find that you are getting too much vitamin D
- You may want to have a loading dose followed by 3 months on maintenance dose, then get a vitamin D test to confirm that you are taking enough

Study of accuracy and repeatability of vitamin D blood spot test Sept 2014
Results There was good agreement between measurements of 25OHD from DBS and plasma; R2 = 0.73 from a regression of plasma concentration on DBS concentration. The within-batch and between-batch intraclass correlations from the 500 replicate measurements were 0.82 (95% confidence interval, 0.80, 0.85) and 0.73 (95% confidence interval, 0.68, 0.78), respectively.
