When the COVID-19 pandemic started, we had insufficient knowledge of clinical clues. The flu-like presentation of COVID-19 makes the management of patients presenting to the emergency service challenging. Our study retrospectively investigated the parameters of neutrophil, lymphocyte, platelet R in 349 moderately and severely COVID-19 PCR+ patients, with or without HR-CT findings. As a result, the CRP, D-dimer, troponin, ferritin, and NLR values were determined to be significantly higher, and the lymphocyte count was significantly lower in the patients with CT involvement, consistent with the literature. Our study aimed to give an idea regarding possible tomographic involvement with the blood tests we performed in COVID-19 PCR+ patients during their first presentation to the emergency service, thus contributing to both the cost-effectivity and the literature on behalf of our district and serving as a guide for the outcome.
