Novel assay of competitively differentiated polymerase chain reaction for screening point mutation of hepatitis B virus

Table 3 Relationship between G1896A variant and HBV DNA level in serum

	HBeAg(+)(n = 56)		HBeAg(-) (n = 48)
	≤ 106copies /ml (n = 14)	> 106 copies /ml(n = 42)	≤ 106 copies /ml(n = 28)	> 106 copies /ml(n = 20)
AS-PCR	2	31	21	19
Competitive	2	35	23	20
AS-PCR
CD-PCR	2	2	21a	8

^aCompared with HBeAg(-) group with a level higher than 10⁶ copies/ml of HBV DNA in serum, Fisher’s exact possibility test, P = 0.0192.
