How soon does DH appear after ingestion?

[smalltownslackermom]

That's my 1st question.
also, is there any info as to when the skin test is valid.
with the bloodtest we are told that we must eat gluten for at least a month or two b4 a bloodtest would be valid, right? is there a similar standard for DH?

Thanks for any pointers - I wasn't finding much by googling...

The IgA levels in the skin can take a long time [months/years] before it goes away.

So, any skin testing should be valid for a while after being GF. Note: I don't have any facts to back me up on this, so I may not be correct.

If you look thru this DH forum, there is info on testing for DH.
