This is true for IgE allergies, but many (sometimes life-threatening) mast cell reactions don't involve IgE and are very difficult to diagnose, since tryptase levels are very hard to measure properly, and the specific variant (alpha) of tryptase is relevant, and that pretty much requires a genetic study only available from one source right now.
It is always good to find triggers - but these can be very numerous (often secondary or transient) in MCAS (mast cell activation syndrome.) Tough job, if MCAS is at work.

I forgot to mention that both daughters had blood in the stools after eating allergens. This is commonly connected with cow's milk protein intolerance but can happen with other allergens.
