Abstract
COVID-19 is an emerging disease that has spread globally and causes death in many countries. The pathogen of this disease is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The public health laboratory is very important for the confirmation of pathogens in order to prevent and control the disease. The purpose of this retrospective study was to find out the positivity rate and turnaround time of SARS-CoV-2 laboratory detection in Bangkok. 156,730 samples were tested from 1st May to 30th September 2021. The pooled positivity rate was 20.4. rRT-PCR method yielded a higher positivity rate than the Ag-RDT method at 28.6% and 13.6%, respectively. The rate of reports within 1 day was 73.4%. The age group with the highest positivity rate was 0 to 15 years old. Cough, fever, and runny nose were the symptoms with the highest positivity rates. The public health laboratory must be prepared the sufficient resources for accurate and early detection of epidemics caused by dangerous communicable diseases.
