How soon can a pregnancy test detect pregnancy?

Pregnancy refers to gestation. A test strip refers to an early pregnancy test strip, which can detect pregnancy generally 10-15 days after conception. If the early pregnancy test strip indicates pregnancy, further examination is needed at the hospital for professional doctors to make a judgment. Generally speaking, about 10-15 days after conception, which is four weeks after the last menstrual cycle, a home pregnancy test strip can be used to detect whether a woman is pregnant. This is because after the fertilization of the egg, the body starts to secrete human chorionic gonadotropin (hCG), which can be detected in urine. However, the sensitivity of test strips may vary by brand. It is recommended to carefully read the instructions and follow the guidance for use. If the test result is negative but pregnancy is suspected, it is advisable to take the test again after a week or follow the doctor's guidance in case of delayed menstruation. During pregnancy, maintaining a balanced diet, engaging in moderate exercise, and avoiding exposure to harmful substances are crucial. Pregnant women should ensure adequate intake of protein, vitamins, and minerals while maintaining moderate physical activity to promote the healthy development of the fetus and their own physical condition. Meanwhile, they should avoid smoking, drinking alcohol, and exposure to harmful chemicals, follow the doctor's advice, and undergo regular prenatal checkups to ensure the health of both mother and baby.
