Results of hepatitis B serologic tests of all study subjects (𝑛=72).

Serologic test	Result	Number of study subjects (%)	Interpretation
HBsAg; Anti-HBsAb; Anti-HBcAb; Anti-HBeAb	Negative; Negative; Negative; Negative	26 (36.1)	Susceptible
HBsAg; Anti-HBsAb; Anti-HBcAb; Anti-HBeAb	Negative; Positive; Positive; Positive	4 (5.6)	Immune due to recent infection
HBsAg; Anti-HBsAb; Anti-HBcAb; Anti-HBeAb	Negative; Positive; Positive; Negative	3 (4.2)	Immune due to remote infection
HBsAg; Anti-HBsAb; Anti-HBcAb; Anti-HBeAb	Negative; Positive; Negative; Negative	35 (48.6)	Immune due to hepatitis B vaccination
HBsAg; Anti-HBsAb; Anti-HBcAb; Anti-HBeAb	Positive; Negative; Positive; Negative	1 (1.4)	Acutely infected
HBsAg; Anti-HBsAb; Anti-HBcAb; Anti-HBeAb	Negative; Negative; Positive; Negative	3 (4.2)	(1) False positive Anti HBc, therefore susceptible; (2) Window period; (3) Resolved infection with waning titers of Anti-HBs; (4) Occult HBV infection (low levels of HBsAg)
