The letters "C" and "T" on a test, often a pregnancy test or a rapid COVID-19 test, stand for "Control" and "Test" respectively. The "C" line indicates that the test worked correctly. If you see a line on "C", it means the test is valid and the results are reliable. The "T" line is where the actual test result appears. If you see a line on "T", it means the test is positive. If there is no line on "T", the test is negative.
Here's how it works in different scenarios:
- Pregnancy Test: If you see both "C" and "T" lines, it indicates a positive result, meaning you are pregnant. If you only see a "C" line, the result is negative.
- Rapid COVID-19 Test: The "C" line indicates the test is working. The "T" line shows whether you have COVID-19. If you see both "C" and "T" lines, the result is positive. If you only see a "C" line, the result is negative.
Important Note: The specific meaning of "C" and "T" can vary depending on the type of test and manufacturer. Always refer to the instructions provided with your test for accurate interpretation.
