To my knowledge, scratch tests cannot.
Certain blood tests can. The one we used was called an ELISA. No test is foolproof though.

My SIL goes to a naturopath, who is in practice with his father, an ENT/Environmental Medicine doctor. They both do the intradermal testing, where they actually squirt the allergen under your skin vs. just a scratch test. The naturopath told my SIL to watch the area for 24 hours afterwards and if it showed any reaction, it was considered an intolerance (where an immediate reaction was an allergy). I have never heard of this before, and considering my DS had the same test and didn't react to any of his allergens, I don't believe it either. I think both reactions he's talking about are IgE allergies (immediate and delayed) where an IgG intolerance is a different mechanism. I thought some lab people mention on here does both an IgG and IgE test on the blood....

Check out my blog (link in sig). I've got a lot of the different types of allergy tests listed there, along with the type of allergies they will show.

That would be me. I went through US BioTek Laboratories, who does a combination IgE/IgG panel. Link to their tests. I believe the accuracy is 85%, assuming that you're not on allergy and/or asthma medications.
