Area of Science:

  • Medical diagnostics
  • Virology
  • Immunology

Background:

  • Herpes simplex virus (HSV) serologies are crucial for diagnosis.
  • Traditional HSV tests often lack type specificity.
  • Newer glycoprotein G-based assays offer improved type specificity.

Purpose of the Study:

  • To review the performance characteristics and limitations of glycoprotein G-based, type-specific HSV serologies.
  • To inform clinicians about available type-specific HSV tests in the US market.
  • To highlight the continued presence of inaccurate HSV serologies.

Main Methods:

  • Literature review of performance data for glycoprotein G-based HSV serologies.
  • Analysis of FDA-approved tests in the United States.
  • Evaluation of product insert information for marketed HSV serologies.

Main Results:

  • Several glycoprotein G-based HSV serologies are FDA-approved for adult use.
  • Market changes necessitate awareness of remaining test sources and claims.
  • Inaccurate HSV tests utilizing crude antigen preparations are still available.

Conclusions:

  • Glycoprotein G-based HSV serologies represent advancements in type-specific diagnosis.
  • Clinician awareness of test accuracy and limitations is critical.
  • Careful selection of HSV serology tests is essential to avoid misdiagnosis.
