An Observational Study on the Utility of Lab Parameters in Evaluating the Severity of Patients in South India with Covid-19.

Laboratory testing has been extremely helpful in determining the severity and determining the course of treatment for COVID-19 patients. Our aim has been to look for variables of patient's clinical and laboratory profile for two weeks and to observe their significance. Observational, Cross-sectional study. Data from the clinic and laboratory were compiled on Google form after informed consent from the patient. Statistical analysis was done using the Mann-Whitney U and unpaired t test. Population statistics included 202 patients (1 week) and 161 patients (2 week), with the mean age of 61 ± 18 years. Most patients fell under the mild category (SPO2 >94%). High body mass index ( = 119) and hypertensive ( = 98) were the most common comorbidities observed. Diabetes, cardiovascular and respiratory diseases are the other comorbidities studied in this study. Hypoalbuminemia ( = 194) is the most deranged laboratory parameter in mild category, followed by lymphopenia ( = 109). In severe category also, hypoalbuminemia ( = 13) was deranged more. Other laboratory parameters included are CRP, D-Dimer, neutrophil and lymphocyte count. This study showed that albumin is a good predictor for estimating the severity of COVID-19 patients especially in the first week of their admission.
