My blood test said I have a milk allergy (moderate), but I still drink milk. Could the blood tests have been wrong? Could it weaken my immune system?

Irrelevant test . Unfortunately, food allergy testing by skin test or blood test is not very predictive.

Allergy RAST/blood (IgE) test reports no milk allergy. Is it possible I could still be allergic to dairy? Suffering from thick nasal mucus.
