Abstract:
OBJECTIVE To study the phenomenon of hepatitis B surface antigen(HBsAg) and antibody(HBsAb) both positive in blood samples.METHODS Using electro-chemo-luminescence immune system E170 to detect HBsAg and HBsAb in clinical samples and retest the both positive cases by another two reagents for HBsAg and another three reagents for HBsAb.RESULTS All 7332 samples showed 140 both HBsAg and HBsAb positive(1.9%) and 73 of them were retested for HBsAb by another three reagents which gave altogether 24 positive results,which was not related to each other.Those gave higher HBsAb value by E170 showed higher positive rate by Abbott reagent.CONCLUSIONS HBsAg and HBsAb both positive results are not rare.It may be due to the interactions between the patient and the infected hepatitis B virus.Besides,the quality of reagents and correct lab operating procedures may also affect the test results.
