Is negative a sign of pregnancy?

In medical testing, "negative" typically refers to a result in which the specific target being tested is not present or is below the detectable level. Regarding pregnancy testing, such as urine pregnancy tests or blood human chorionic gonadotropin (hCG) tests, a "negative" result means that there is currently no detected sign of pregnancy.

However, negative results are not always absolutely accurate. The test may yield false-negative results for various reasons, such as performing the test too early, when hCG levels may still be too low to be detected in early pregnancy, or due to improper testing methods. If the initial test result is negative but pregnancy is still suspected, it is recommended that women repeat the test one week after the expected menstrual period has been missed. It is also important to ensure the use of high-quality, reliable testing kits and to follow the instructions carefully for the most accurate results.

Therefore, a negative result usually indicates that pregnancy was not detected, but it is not absolute and should be interpreted according to the specific circumstances.
