It is acknowledged that many clinicians may not be in a position to distinguish the mechanism of a particular reaction. Often the term \"allergy\" is used rather generically and may overlap with the use of \"intolerance\" - in practice the boundaries between these two concepts may not be well-defined or understood. This data element is included nevertheless because many legacy systems have captured this attribute. Immunological testing may provide supporting evidence for the basis and causative substance , but no tests are 100% sensitive or specific for sensitivity to a particular substance.
