YBL Native CA 72-4 salient features

  • Purity percentage: Low cross contamination for CA 125, CA 19-9, CA -15-3, CEA, AFP and Ferritin was observed and cross contaminants are reported as activity of cross contaminants/activity of CA 72-4 in U/ml. The passing criteria is < 25% however, YBL tries to restrict the levels to <10% for cross contamination.
  • Stability data: CA 72-4 low cross (part pure) is stable for 3 years at 2-8° C based on the real time stability study.
  • Testing Method: ECLIA
  • Testing Platform: Roche-cobas
  • Viral testing: The viral marker test for HBs-Ag, Anti-HCV and Anti-HIV (I and II) was done using CLIA (US-FDA Approved). The antigen was also tested for the absence of viral DNA/RNA for HBV, HIV (I) and HCV using PCR technology.
