A Prospective Cohort Study on Suspected COVID-19 Patients undergoing Nasopharyngeal Swab PCR and HRCT
Nasopharyngeal Swab PCR and HRCT in COVID-19 Patients
Objective:To Determine the Specificity, Accuracy and Sensitivity of HRCT in Diagnosis of Covi-19.
Methods: Prospective cohort study was done with 181 participants who were suspected for COVID-19 infection and were followed to evaluate PCR and HRCT reporting in patients with clinical symptoms.
Results: 86.8% of patients had a dry cough, followed most commonly with shortness of breath. 65 (35.9%) of patients had ground-glass opacities of haze on HRCT followed by 47 (26 %). who had consolidations present. 147 (81.2)patients had a positive PCR whereas 34 (18.7%) was negative had an HRCT that was suggestive of having COVID-19 pneumonia.
Conclusion:In conclusion clinical symptomatology, HRCT findings and PCR all should be used in a triple examination. It is concluded that a positive PCR test is very specific and used to make diagnosis for Covid-19. CT has a higher sensitivity but a lower specificity, thus helping with disease diagnosis and therapy.
