Affiliation and essence of SARS CoV2 (COVID-19) on blood parameters of infected patients: A retrospective study.

Background: Till date, SARS CoV2 (COVID-19) is a pandemic viral infection in the world with the main and strong impact on respiratory airway, but this virus can affect any system of the human body.

Aims: This research is aimed to dictating the effect of SARS CoV2 infections on hematological, biochemical, and arterial blood gas parameters by using their mean values.

Settings And Design: This retrospective study was included a total no. of 97 SARS CoV2 positive patients from 27 March to 15 May 2020. All positive patients were consented and took all the significant details.

Materials And Methods: We review the total 97 COVID-19 positive patients after obtaining all the hematological and other relevant clinical data from laboratory and medical records. The subjects were tabulated into three categories named; admitted (Gp A), discharged (Gp B), and expired (Gp C) patients and compared their hematological, biochemical parameters, and arterial blood gas analysis by using blood or serum and processed by proper methods.

Statistical Analysis: The data was cleaned, edited, checked for completeness, and processed then entered in SPSS version 20 statistical software.

Results: Blood samples were collected of all positive patients. Most of the patients had X-ray changes. Blood parameters showed that patients who were expired (Gp-C) suffered from anemia, lymphopenia, leucoytosis, neutrophilia, and thrombocytopenia with high ALT, pCO and low pO than admitted and expelled patients.

Conclusions: Result from this study provides that WBC count, absolute lymphocyte count, neutrophil count, and pO were independently associated and an important forecaster of mortality from SARS CoV2. All healthcare provides to regularly monitor above parameters indicators of COVID-19 infected patients to improve their quality of life and to reduce the risk of mortality rate.
