Serological testing for HSV-2 has a high degree of clinical accuracy
While modern automated and point-of-care serological assays demonstrate high clinical accuracy on specific platforms, test performance varies widely by manufacturer, and limitations in specificity caution against routine general population screening.
The claim is specific and falsifiable, meeting Step 0 criteria. The retrieved literature shows a mixed picture: while several modern assays (e.g., Roche, Alinity-i, and certain rapid tests) demonstrate high sensitivity and specificity for HSV-2 IgG, other widely used commercial platforms (such as DiaSorin) suffer from significant false-positive rates at low-positive index values. Additionally, clinical guidelines emphasize that test performance limitations and interpretive challenges restrict routine general population screening. Consequently, the overall evidence is contested rather than unconditionally supported.
Serological testing for HSV-2 demonstrates high accuracy on specific automated and point-of-care platforms, though performance varies by manufacturer and limitations caution against routine general population screening.

Studies such as this one demonstrate high sensitivity and specificity for several established type-specific serological assays when compared to the Western blot gold standard.

Other automated assays, such as DiaSorin, show comparatively poor performance metrics with high rates of false positives at low-positive index values.

Certain automated platforms like Roche exhibit high sensitivity and specificity (>98%) for HSV-2 IgG detection.

Recent evaluations of automated chemiluminescent immunoassays demonstrate excellent sensitivities and specificities for anti-HSV-2 IgG detection.

Clinical guidelines frequently advise against routine general population screening due to limitations in test specificity and potential psychosocial harms.
