Rapid Antigen Test (RAT)

Dear Patients,

The team from Carlingford Epping Surgery hopes you are staying safe and well, especially for those who are going back to the office or school. With the wide adoption of Rapid Antigen Tests (‘RAT’), following are some basic information about RAT from the NSW Health Department.  


Rapid Antigen Test (RAT) 

What happens if I get a positive RAT result? 

If you get a positive RAT result and unsure of the next step, you may follow the guideline below. 

Test result  Symptoms  Exposure risk  Next step 
Known or unknown contact  You are a confirmed case, follow the advice for people testing positive for COVID-19 
  Or  Known high risk or household contact  You are a confirmed case, follow the advice for people testing positive for COVID-19 
  No known contact  You may be a confirmed case. Take another rapid antigen test within 24 hours or have a PCR test 

What type of RAT should I use? 

The Therapeutic Goods Administration provides a full list of RAT kits approved in Australia and how to use each one correctly. Please refer to https://www.tga.gov.au/covid-19-rapid-antigen-self-tests-are-approved-australia 


How do I use a RAT kit? 

Each RAT differs slightly so please follow the instructions of the RAT you are using. NSW Health has provided a quick video on how to use a basic nasal test. Click Here to watch the video.  


Can I eat or drink before using a saliva sample RAT? 

The answer is, “No. NSW Health recommends you do not eat, drink or brush your teeth for at least 30 minutes before doing a saliva rapid antigen test. This will ensure a clean sample is taken.”

  • A negative or invalid RAT result 
  • A positive PCR test in the 28 days before your positive RAT
