Clinical Validation Data for Integrated TORCHes Pathogen Detection System

210 clinical samples were used to validate an integrated diagnostic system for TORCHes pathogens. The system achieved near-perfect agreement with commercial qPCR (Kappa = 0.965–1.000), with all discrepant results confirmed correct by Sanger sequencing. The dataset supports the evaluation of sensitivity, specificity, precision, and stability metrics for the novel method.

Use Cases

• Validate the diagnostic sensitivity and specificity of the integrated system using the 210 clinical sample results compared to qPCR.
• Analyze the stability of freeze-dried microspheres over a 1-year room-temperature storage period using stability testing data.
• Assess the limit of detection (LoD) for each pathogen, such as the 200 copies/mL for HSV-I/II, HCMV, and TOX.
• Evaluate the repeatability of melting temperature (Tm) measurements using the reported intra- and inter-batch coefficient of variation (CV) of 0.03–0.18%.
• Compare the automated interpretation results from TORCHes-MCAv1.0 software with manual interpretation to verify 100% concordance.

Strengths

• Clinical validation involved 210 samples, providing a substantial basis for method evaluation.
• The system demonstrated high analytical sensitivity with limits of detection as low as 200 copies/mL for several pathogens.
• Freeze-dried reagents showed excellent stability, confirmed to be storable at room temperature for 1 year.
• Validation metrics include specific quantitative results like Kappa agreement scores (0.965–1.000) and Tm CVs (0.03–0.18%).

Limitations

• The dataset is contained within a 1.3 MB document file, limiting structured, machine-readable analysis.
• The sample size of 210 clinical specimens may be insufficient for detecting rare pathogen subtypes or low-prevalence conditions.
• The data is specific to the validation of a single prototype system and may not generalize to other diagnostic platforms or sample populations.
