Due to vast limitations in hospital resources, some countries have encountered serious problems for fair access to hospital beds. An interesting letter in this journal recommended 6-minute walk test (6MWT) as a proper clinical test to determine the necessity for going to the hospital in patients with suspected COVID-19. 6MWT is a field exercise test in which, patient should walk for 6 minutes as far as possible. It is usually used to compare pre- and post-treatment conditions in many pulmonary and cardiac disorders or to estimate functional status of individuals with some pulmonary and cardiovascular diseases. This test may be applied as a predictor of morbidity and mortality in these patients. Although the idea of finding an applicable and feasible clinical test to do at home is valuable by itself, but in our opinion, there are great concerns to use 6MWT for this purpose. Here, we will discuss about some serious concerns about the practical, judicious and scientifically justified use of this test in patients with suspected COVID-19. https://fem.tums.ac.ir/index.php/fem/article/view/416 https://fem.tums.ac.ir/index.php/fem/article/download/416/291
