HEV infection leads to an estimated 3.3 million symptomatic cases of viral hepatitis and 70,000 deaths in human populations each year. Therefore, a rapid and accurate method for detecting HEV in serum or stool samples is essential. In this study, we aimed to develop and evaluate two methods for the rapid and convenient detection of HEV RNA: reverse transcription recombinase-aided amplification with lateral flow dipstick (RT-RAA-LFD) and quantitative real-time reverse transcription recombinase-aided amplification (qRT-RAA). We optimized the reaction conditions and assessed their sensitivity and specificity. The RT-RAA-LFD assay completed its reaction at 39\u00b0C within 15 minutes, achieving a 95% limit of detection (LOD) of 247 copies\/\u03bcL. The qRT-RAA assay, completed at 42\u00b0C within 20 minutes, had a 95% LOD of 25 copies\/\u03bcL. Both assays demonstrated no cross-reactivity with other porcine pathogens and exhibited strong specificity. In testing 245 porcine bile and fecal samples, the RT-RAA-LFD assay showed a kappa value of 0.943 (\n              <jats:italic>P<\/jats:italic>\n              &lt; 0.001) with a 97.14% (238\/245) coincidence rate compared with quantitative reverse transcription PCR. Similarly, the qRT-RAA assay achieved a kappa value of 0.976 (\n              <jats:italic>P<\/jats:italic>\n              &lt; 0.001) with a 98.78% (242\/245) coincidence rate. In conclusion, these two RT-RAA assays show promising potential as effective diagnostic tools for broad and efficient screening of swine HEV in veterinary clinics.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>IMPORTANCE<\/jats:title>\n            <jats:p>Hepatitis E virus (HEV) is a globally widespread zoonotic pathogen that poses a significant public health risk.
