What does the c and t mean on a hospital pregnancy test?

A pregnancy test measures the level of human chorionic gonadotropin (hCG) in a person's urine. The hCG hormone helps to keep an egg implanted in the uterus and support the early development of the fetus.

"C" stands for "control" and "T" stands for "test." The test line (T) will show up if hCG is detected in the urine. This indicates that the person may be pregnant. The control line (C) should always show up, regardless of whether or not hCG is present in the urine. This is to ensure that the test is working properly.
