The article mentions testing for each one separately.
But I don't know if it is available for people outside research communities, etc.
The folic acid/folate thing is rather new, and comes to attention because of food fortification with folic acid (synthetic), and the
new attention on the DNA polymorphisms that genetically hamper
methylation of B12 and folic acid. These things are all happening at once, and it takes time to reach clinical physicians seeing patients.
I don't have an answer for the folic acid/folate question yet.
