Rhinomanometry may be used to measure only one nostril at a time (anterior rhinomanometry) or both nostrils simultaneously (posterior rhinomanometry). In anterior rhinomanometry, the patient is asked to blow his nose, sit in an upright position, and the pressure sensing tube is placed in one nostril, while the contralateral nostril is left opened.
The intradermal allergy test is more sensitive than the skin prick test, but is also more often positive in people that do not have symptoms to that allergen. [ 40 ] Even if a person has negative skin-prick, intradermal and blood tests for allergies, they may still have allergic rhinitis, from a local allergy in the nose.
The diagnosis is made on the clinical picture. Routine blood tests (complete blood count, electrolytes, kidney function, liver enzymes) are typically performed. Mast cell tryptase levels may be elevated if the attack was due to an acute allergic (anaphylactic) reaction.
It has been shown that the cilia of the congested side suspend their motility until that side decongests. Thus the cycle ensures that one side of the nose is always moist, to facilitate humidification, which is one of the three functions of the nose, the other two being filtration and warming of inspired air prior to its entering the lungs.

A validated ENS-specific, 6-item questionnaire called the Empty Nose Syndrome 6-item Questionnaire (ENS6Q) was developed as an adjunct to the standard Sino-Nasal Outcome Test 22 (SNOT-22). [20] The ENS6Q is the first validated, specific, adjunct questionnaire to the SNOT-22. It can more reliably identify patients suspected of ENS. [21]
