Advantages and disadvantages of the methods for the diagnosis of conjunctivitis.

Adenoviral Keratoconjunctivitis
	Advantages	Disadvantages
Cytologic examination	rapid	quite limited for the clinic
(mononuclear cells)		auxiliary diagnosis
Genetic testing	rapid	require the well-equipped laboratory
(e.g., nested-PCR, real-time PCR)	high sensitivity
Test kit (e.g., Capilia Adeno Eye®)	rapid	limited accuracy
(virus antigen)	easy-to-perform
Allergic Conjunctivitis
	Advantages	Disadvantages
Cytologic examination	rapid	quite limited for the clinic
(eosinophils)	confirmed diagnosis
Serum testing	confirmed diagnosis	time-consuming
(allergen-specific serum IgE)		require the well-equipped laboratory
Test kit (e.g., Allerwatch®)	rapid	limited accuracy
(total tear IgE)	easy-to-perform

PCR, polymerase chain reaction.
