No, a positive test result was associated with only one long COVID symptom: "A serology test result positive for SARS-COV-2 was positively associated only with persistent anosmia (odds ratio, 2.59; 95% CI, 1.57-4.28), even when restricting the analyses to participants who attributed their symptoms to COVID-19 infection" The study conclusion says so: "Although our study cannot determine the direction of the association between belief and symptoms, our results suggest that further research regarding persistent physical symptoms after COVID-19 infection should also consider mechanisms that may not be specific to the SARS-CoV-2 virus. From a clinical perspective, patients in this situation should be offered a medical evaluation to prevent their symptoms being erroneously attributed to COVID-19 infection and to identify cognitive and behavioral mechanisms that may be targeted to relieve the symptoms.23"
