                &lt;/td&gt;
                &lt;td&gt;Allergy&lt;/td&gt;
                &lt;td&gt;A propensity for hypersensitive reaction(s) to a substance.  These reactions are most typically type I hypersensitivity, plus other &amp;quot;allergy-like&amp;quot; reactions, including pseudoallergy.&lt;/td&gt;
              &lt;/tr&gt;

                &lt;/td&gt;
                &lt;td&gt;Intolerance&lt;/td&gt;
                &lt;td&gt;A propensity for adverse reactions to a substance that is judged to be not allergic or &amp;quot;allergy-like&amp;quot;.  These reactions are typically (but not necessarily) non-immune.  They are to some degree idiosyncratic and/or patient-specific (i.e. are not a reaction that is expected to occur with most or all patients given similar circumstances).&lt;/td&gt;
              &lt;/tr&gt;
