In the context of a pregnancy test, "C" typically stands for "Control" and "T" stands for "Test." These markings are found on the result window of the pregnancy test device.
Control Line (C): This line indicates that the test has been conducted correctly and that the control solution or sample has moved through the test properly. It serves as a confirmation that the test is working correctly, regardless of whether the result is positive or negative for pregnancy.
Test Line (T): This line appears if the test detects the presence of human chorionic gonadotropin (hCG), a hormone produced by the placenta during pregnancy. The appearance of this line indicates a positive result, indicating that pregnancy has been detected.
When interpreting the results of a pregnancy test, it's important to follow the instructions provided with the test kit and to understand the meaning of each line to accurately determine the result.
