High Folate Levels

Has anyone had high folate levels during pregnancy? I'm 29 weeks and my OB tested me last week for anemia (I'm slightly anemic at 11.7, normal 12 to 15.5), and she also ran my B12 and folate levels (B12 was normal).

My folate levels came back as >22 which was flagged as high (not sure of the exact value). The NP who viewed my labs said that "vitamin levels were normal, high folate levels not concerning".

BUT... I made the horrible mistake of googling and found a study that showed an association between high folate levels at the time of birth and an increased risk of autism. It was one study, but I'm obviously freaking out about it.

I'm asking my OB her opinion on it at my next appt next week. But just wondering if anyone had any insight into this...
