Comparison of clinically used viral diagnostics tests.

Virus	Method	Detection limit	Advantages	Disadvantages	Refs.
Influenza	isolation and identification of the virus	1 EID50/mL	sensitivity	time consuming	[47]
	ELISA	1.0 ng	rapid	high rate of false positive results	[48]
	RT-PCR	0.0256 HAU	specificity sensitivity	expensive complicated, highly skilled stuff	[49]
	qRT-PCR	10 copies /reaction			[50]
HBV	ELISA	0.5 pg/mL	as presented above		[51]
	qRT-PCR	18 IU/mL			[52]
HIV	ELISA	0.9–1.2 IU/mL			[53]
	qPCR	18–65 copies/mL			[54]
