Update Dec 2013: sold 200,000 testers in Asia since introduced in April
After FDA approval, the price is expected to be under $30 per test (single use)
- If you ask the question: Is my vitamin D level <32 ng/mL (80nmoles/L)
It essentially gives a Yes/No answer in 10 minutes.
- It is being sold some places outside of the US already
The version currently being sold shows a red line if the vitamin D level is less than 32 ng/mL (80nmoles/L).
The accuracy is +- 6ng/mL .
Just needs a drop of blood - from a finger prick.
Note: The accuracy of most quantitative testers of vitamin D is about +- 3 nanograms,
and those are far more expensive, and results often are not available the same day, much less while the patient is still in the office.
While it is technically possible for them to make a disposable tester for say 50 nanograms, they do not (currently) perceive a market.

(The blood will go into pipette all by itself)
PLACE pipette in the square hole and PRESS bulb to force the blood out
PUT 7 drops of reagent chemical in the round hole,

Two red lines = low vitamin D
One red line = good level of vitamin D
