On a pregnancy test, the "R" typically stands for "Reference" or "Control" and indicates that the test is working properly. The "C" is the "Control" line that must appear to confirm the test is valid. If the "R" or "C" line appears, it means the test has functioned correctly, while the "T" line (Test) indicates the presence of the pregnancy hormone hCG if it appears alongside the "C" line.
