    This study introduces a rapid enzyme immunoassay for detecting herpes simplex virus type 1 (HSV-1). The assay shows high specificity but its sensitivity for HSV-1 detection is influenced by sample storage duration.

    Area of Science:

    • Virology
    • Immunology
    • Diagnostic Assays

    Background:

    • Herpes simplex virus type 1 (HSV-1) is a common human pathogen.
    • Rapid and accurate diagnostic methods are crucial for timely clinical management.
    • Existing diagnostic techniques may have limitations in speed or sensitivity.

    Purpose of the Study:

    • To evaluate the performance of a novel enzyme immunoassay for the rapid detection of HSV-1.
    • To determine the specificity and sensitivity of the assay using clinical samples.
    • To assess the impact of sample storage conditions on assay sensitivity.

    Main Methods:

    • Enzyme immunoassay utilizing solid-phase immobilized HSV-1 specific antibodies.
    • Detection of HSV-1 in laboratory preparations and clinical samples.

  • Comparison of immunoassay results with tissue culture isolation methods.
  • Evaluation of sensitivity based on varying sample storage durations (frozen).

    • Main Results:

    • The enzyme immunoassay detected HSV-1 in laboratory preparations at levels >= 50 50% tissue culture-infective doses.
    • Clinical sample testing yielded a specificity of 95%.
    • Sensitivity was significantly affected by storage time: 46% compared to initial tissue culture when stored for 3-6 months, but 89% compared to re-isolation from the same samples.
    • The assay detected HSV in 7/10 positive samples stored frozen for <= 2 weeks.

    Conclusions:

    • The developed enzyme immunoassay offers a rapid and specific method for HSV-1 detection.
    • Assay sensitivity is dependent on sample storage duration, with shorter storage periods yielding better results.
    • Further optimization may be needed to enhance sensitivity for long-term stored samples.
