Questionnaires containing the index tests and reference tests were distributed to blood donors at blood banks between June and December 2021 in Region Zealand, Denmark. The index tests were the two questions \u2018Have you had troublesome sweating?\u2019 and \u2018Have you ever had troublesome sweating?\u2019, which were used to create six single-item algorithms for classifying PHH.

The algorithms with the highest combined sensitivity and specificity were algorithm 2 with a sensitivity of 0.94 (95% CI 0.77\u20130.99) and specificity of 0.94 (95% CI 0.92\u20130.95), and algorithm 5 with a sensitivity of 0.94 (95% CI 0.80\u20130.99) and specificity of 0.92 (95% CI 0.90\u20130.94).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>With high diagnostic accuracy, these items allow for the identification of individuals with and without PHH, which may prove useful in epidemiological research.
