Aim: Ongoing investigations have proposed that chest figured tomography checks could be utilized as an essential screening or symptomatic apparatus for COVID illness 2019 (Coronavirus) in pandemic areas. Purpose: To play out a meta-examination to assess symptomatic execution measures, counting prescient qualities, chest CT and Reverse Transcriptase-Polymerase chain reaction (RT-PCR). Materials and Methods: MEDLINE and Embase looked at COVID 19 concentrates for the results and additionally particularities of CT testing and RT-PCR testing at Mayo Hospital, Lahore from February 2020 to July 2020. The combined impact characteristics and consistency were analyzed by using unusual impact models. Results: The pool of results for Chest CT was 97% (96% CI: 92%), 97% (I4=96%), and 87% (96% CI: 80%, 97%, and I2=93%) of Chest CT. RT-PCR was 97%. For Chest CT filters, the Positive Predictive value increased from 2.7% to 35.8%, while the Negative Predictive value ranged from 95.4% to 99.8%. The PPV was between 49.7% and 99.8% for the RT-PCR, while the NPV was between 96.8% and 97.8%. CT was determined by the distribution of ailment duration, the number of comorbidity patients, and the number of asymptomatic patients (all p<0.05). The misfortune of RT-PCR with the magnitude of old PCR (p=0.02) was adversely associated. Conclusion: In comparison, the chest CT test for patients with suspected illness was not very normal in the region of COVID–19 (1–23.8%) (2.6–31.8% of the suspected illnesses).
