Dataset Information

Rapid one-tube RPA-coupled CRISPR/Cas12a-based RID-MyC assay for the diagnosis of fungal keratitis.

ABSTRACT:

Purpose

This study introduces and evaluates the single-tube rapid identification of mycoses using CRISPR (ST-RID-MyC) assay. This novel diagnostic tool combines recombinase polymerase amplification (RPA) with CRISPR/Cas12a for the rapid and precise diagnosis of fungal keratitis (FK).

Design

Prospective cross-sectional study.

Methods

Corneal scrapings from 61 patients with suspected microbial keratitis were collected at the Cornea Department of a Tertiary Eye Care Center. The study assessed the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the ST-RID-MyC assay. Additional measures included concordance rates with traditional diagnostic methods and the time to diagnosis.
