Q. Is RAT or RT-PCR more accurate when taking COVID test?
Hello doctor,
I have a question regarding a negative and positive COVID-19 test. I have received both in three days, and I am not sure what to believe. I need another opinion. Please advise.
Thank you.
Hello,
Welcome to icliniq.com.
I understand your concern. Can you please tell me in detail when were you tested positive and when negative? Have you done the RT-PCR (reverse transcription-polymerase chain reaction) or RAT test (rapid antigen tests)? What are your current symptoms, and when did you have your first symptom? What are the medications you are taking? Are you vaccinated? Please answer the above to help you better.
Thank you.
Thank you doctor,
I was dealing with normal sinus issues, mainly postnasal drip. I took a home RAT that came back negative. I then went to a testing facility and had another RAT done to be sure. That one also came back negative. Later I had more sinus issues, sneezing, runny, stuffy nose, and a little sinus pressure. After a day, I felt much better, so I did another home RAT to follow-up, and this time it came back positive. I then went to another facility to have a RAT done, and that one came back positive as well. What does that mean? I do not have any symptoms anymore. I received the Pfizer vaccine, but I am not eligible for a booster. I am not currently taking any medication. Please advise.
Hello,
Welcome back to icliniq.com.
The RAT test may sometimes show false negative or false positive, or maybe the viral load was less or the sample was not appropriately taken earlier. Still, as of now, you tested positive. If your symptoms are relieved, then there is no need to take medications, but you have to isolate yourself and follow approved guidelines for preventing COVID. If you live with someone, get them tested too. Please get appropriate medical attention on time if you have any symptoms or anything else.
Thank you.
