Rt-pcr For Covid-19 (8)

Reverse transcription-polymerase chain reaction for COVID-19 is the benchmark test due to its precision and trustworthiness. First, the sample, either nasal or nasopharyngeal, is collected from the respiratory tract. It is then sealed and sent to the laboratory to extract the SARS-CoV-2 virus's genetic material, and the thermal cycler multiplies it. Finally, fluorescent color is produced, indicating a positive report. Results are usually given within 24 hours. One shortcoming is that it shows a positive result even after becoming non-contagious.
