Collaborative study to establish a proficiency panel of hepatitis B surface antigens for evaluating in vitro diagnostics.

Abstract
Hepatitis B virus (HBV) infection is a critical health issue. In hospitals, in vitro diagnostic devices (IVDs) are used to detect HBV infections. The Taiwan Food and Drug Administration has prepared a candidate hepatitis B surface antigen (HBsAg) proficiency panel as an analytical standard to evaluate the sensitivity of the postmarketing surveillance of HBV IVDs. The sensitivity and stability of the proficiency panel, which comprises 5 HBsAg positive sera (SN-A to E) and 1 negative serum, was determined by a collaborative study involving 8 collaboratories. The potency of the candidate proficiency panel was consistent among all collaboratories. The potencies of sera SN-A to E in semiquantitative and quantitative analyses were 2.823-0.011 and 2.229-0.009 IU/mL, respectively. The mean coefficients of variation (CV) of intra and interday precision among the collaboratories were <7%. Accelerated degradation and long-term storage tests were used as stability assays. The candidate HBsAg proficiency panel exhibited good stability under different storage conditions, while all CVs were <6%. In conclusion, this candidate HBsAg proficiency panel is credible and reliable. Therefore, it can be used for postmarketing surveillance of HBV IVDs and quality assessment by clinical researchers and IVD manufacturers.
