INTERPRETING THE RESULTS POSITIVE (Two coloured lines appear in control region and test region) One purple line next to “C” and. one purple line next to “T” Indicates COVID-19 posi ve.
If your result is positive, you will see 2 lines on the test. A pink line next to C and a pink line next T. This means you have a positive COVID-19 result. If your result is negative, you will see one line next to C. If you have a void result, you will see a line next to T.
If a test line (T) is visible together with a control line (C), this means that the result is positive. Look carefully at the result: The test should be considered positive if two lines are visible - even if they are faint. A positive test result means it is very likely that you have COVID‑19.
Look very closely for line next to “T”. This line can be very faint. Any visible pink/ red “T” line is a positive result when the “C” line is also present. Repeat testing does not need to be performed if patients have a positive result at any time.
only the “C” position, this indicates a negative test. If you see a line appearing at. only the “T” position, the test is invalid.
If you see any line on your COVID test, err on the side of caution and take precautions to avoid spreading the virus to others. While a dark line that shows up quickly is a sign that there's more virus in your body, even a faint line can be positive (and may turn darker if you test again in the coming days).
Distinct and consistent color bands appear on the Control (C) and Test (T) regions. Color intensity of the bands may vary according to concentration and level of hCG development. The test line is usually slightly weaker in intensity in comparison to the control line.
This is what the test “window” looks like in the strip after 30 minutes. “C” stands for “control” – this is to make sure the test is working. “T” stands for “test” – this is where your sample result will appear.
Positive Result
A red line appears in both the test line region 'T' and the control line region 'C'. A Positive result indicates the presence of SARS-CoV-2 antigen in the sample. Even if the test line is weak or incomplete it should be interpreted as a positive result.
*Do NOT read results before 15 minutes or after 20 minutes as it may give inaccurate results. line appeared first or how faint the lines look. If only the control line (C) is present, the result is negative. If both control line (C) and test line (T) are present, the result is positive.
A positive rapid antigen test is highly indicative that you have COVID-19, and you are required to self-isolate, in accordance with guidance. A confirmatory PCR test or any follow-up testing is not necessary after a positive rapid antigen test.
The bottom line can be very faint. Any pink/purple line visible here indicates a positive result.
If you have 1 line by C, and 1 line by T this is called a positive result. The lines can be bright or faint. You have COVID-19. If you have 1 line by C, and no line by T this is called a negative result.
Antigen tests look for pieces of proteins that make up the SARS- CoV-2 virus to determine if the person has an active infection. Serology looks for antibodies1 against SARS-CoV-2 in the blood to determine if there was a past infection.
Reading the results
A positive result: Two lines on control (C) and test (T). Negative: One line on control (C). Invalid: No lines or only a test line mean the results are invalid and it needs to be taken again.
1. Negative result:The presence of only the control line (C) and no test line (T) within the result window indicates a negative result. 2. Positive result: The presence of the test line (T) and the control line (C) within the result window, regardless of which line appears first, indicates a positive result.
If the extracted specimen contains SARS-CoV-2 antigens, a pink-to-red Test Line, along with a blue procedural Control Line will appear on the Test Strip indicating a positive result. If SARS-CoV-2 is not present, or is present at very low levels, only a blue procedural Control Line will appear.
you have COVID-19. The result is positive even if the second line is very faint. Isolate for 7 days and follow the advice at www.coronavirus.vic.gov.au/checklist-cases. Report your result to the Department of Health at www.coronavirus.vic.gov.au/report or on 1800 675 398.
One coloured line should be in the control line region (C), and another coloured line should be in the test line region (T). Two lines, one next to C and one next to T, even faint lines, show the test is positive.
Find result window and look carefully for two lines. Positive Result: If you see two lines, Control (C) line and Test (T) line, this means COVID-19 was detected. If positive, please contact your doctor or local health department immediately and follow local guidelines for self-isolation.
You are most infectious (or contagious) in the first 5 days after your symptoms start. You can also spread COVID-19 in the 48 hours before your symptoms start. If you never have symptoms, consider yourself most infectious in the 5 days after you test positive.
Two lines – even faint lines – indicate the test is positive. The test has failed and should be retaken.
People with moderate or severe COVID-19 should isolate through at least day 10. Those with severe COVID-19 may remain infectious beyond 10 days and may need to extend isolation for up to 20 days.
If I Have COVID-19, How Long Am I Contagious? According to the CDC, if you have mild to moderate COVID-19, you may be contagious for 10 days from the first day you noticed symptoms. If you were severely affected or critically ill from COVID-19, you may stay infectious for up to 20 days from the start of your symptoms.
Note: A Control (C) line may appear in the result window within a few minutes but a Test (T) line may take as long as 15 minutes to appear. Note: After 20 minutes the result might become inaccurate. Note: Be careful not to spill the Tube contents.
