Accurate and Early Diagnosis of Monkeypox Crucial for Controlling Epidemics

Strategic Insights -

A recent study emphasizes the significance of prompt and accurate diagnosis in controlling monkeypox outbreaks. Conducted by researchers at the Shenzhen Center for Disease Control and Prevention, the study aimed to evaluate the performance of three commercial monkeypox diagnostic assay kits. The researchers tested the kits on 117 clinical patient specimens, artificially created positive samples, and virus cell culture supernatant.

Key Takeaways:

  • The study assessed the analytical and clinical performance of the MolecisionTM Monkeypox Virus qPCR Assay, Biorain Monkeypox Virus ddPCR Assay, and MAGLUMI® Monkeypox Virus Ag (chemiluminescence immunoassay, CLIA) Assay.
  • The Biorain Monkeypox Virus ddPCR Assay had a limit of detection (LoD) of 3.89 CCID50/mL, while the MolecisionTM Monkeypox Virus qPCR Assay had an LoD of 15.55 CCID50/mL.
  • The MAGLUMI® Monkeypox Virus Ag (CLIA) Assay had an LoD of 0.500 pg/mL.
  • The accuracy of the MolecisionTM Monkeypox Virus qPCR Assay was comparable to the Biorain Monkeypox Virus ddPCR Assay, and the MAGLUMI® Monkeypox Virus Ag (CLIA) Assay demonstrated high sensitivity.
  • The specificity of all three MPXV diagnostic assays for clinical specimens with potential cross-reacting substances was 100%.
  • The study provides valuable insights into the clinical application of monkeypox assays, supporting efforts to mitigate and control the spread of monkeypox.

Statistics:

  • 117 clinical patient specimens were tested in the study.
  • The Biorain Monkeypox Virus ddPCR Assay and MolecisionTM Monkeypox Virus qPCR Assay had the following limits of detection:

+ Biorain Monkeypox Virus ddPCR Assay: 3.89 CCID50/mL.

+ MolecisionTM Monkeypox Virus qPCR Assay: 15.55 CCID50/mL.

  • The MAGLUMI® Monkeypox Virus Ag (CLIA) Assay had a limit of detection of 0.500 pg/mL.
