Introduction

In general, a single line indicates not pregnant. Pregnancy tests or early pregnancy test strips detect pregnancy by measuring the level of human chorionic gonadotropin (hCG) in urine. If a person is pregnant, hCG levels rise and will show two lines during testing. A single line may indicate that the level of hCG in the urine has not reached the threshold required for a positive result, so it usually means the person is not pregnant.

Generally, a single line on a pregnancy test indicates that you are not pregnant. If you experience any discomfort, it is recommended to seek medical attention at a正规 hospital promptly. The detailed explanation is as follows:

Pregnancy tests, such as test strips or sticks, detect the presence of human chorionic gonadotropin (hCG) in urine. When a woman is pregnant, hCG levels rise, resulting in two lines appearing on the test. A single line usually means that the level of hCG in the urine has not reached the threshold required for a positive result, indicating that pregnancy is unlikely. However, there are special circumstances: testing too early, before hCG levels have risen sufficiently after conception; or issues with the test strip's quality or incorrect usage may lead to false-negative results.

If you suspect you might be pregnant despite a single line on the test, wait a few days and retest, or go directly to a hospital for a blood hCG test and an ultrasound examination to confirm whether you are pregnant. In daily life, maintain a healthy lifestyle, practice good personal hygiene, eat a balanced diet, and engage in moderate exercise to support overall well-being.

Is it normal for an antigen test to show only one line?

The term "antigen" may refer to the SARS-CoV-2 antigen test. Generally, in a SARS-CoV-2 antigen test, the meaning of a single line depends on its location. If the single line appears in the C region, the result is normal; if it appears in the T region, the result is abnormal. The novel coronavirus primarily spreads through respiratory droplets. After infection, patients may experience symptoms such as fever and cough.

First pregnancy test showed two lines, second showed one line

If you have any concerns, it is recommended to consult a doctor. When using a pregnancy test strip, wash your hands first, then place the test strip into a clean container.

My period is 9 days late, but the pregnancy test strip shows only one line. Should I still go for a blood test?

In general, if a woman's period is delayed by 9 days and the pregnancy test strip shows only one line, she may or may not need to get a blood test, depending on the specific circumstances. If a woman has had regular unprotected sexual intercourse, a 9-day delay in menstruation with a negative urine test could be due to early pregnancy, when hormone levels are still too low for the test strip to detect.

One line indicates how long ovulation has occurred

In general, a single line on an ovulation test strip cannot directly indicate how long ovulation has occurred. This result may suggest that the ovulatory phase has not yet begun, has already passed, or that ovulation did not occur. The interpretation should be combined with the testing time and menstrual cycle. For more accurate determination of ovulation timing, it is recommended to combine basal body temperature monitoring and changes in cervical mucus.

Is a faint and a dark line on a pregnancy test stick a sign of impending menstruation?

Under normal circumstances, a pregnancy test stick showing one dark line and one faint line is usually not a sign of an upcoming menstrual period, and may indicate pregnancy.

What does it mean if a pregnancy test strip shows one dark line and one light line?

Hydatidiform mole is a disease formed by the abnormal development of a fertilized egg. This condition may lead to elevated levels of human chorionic gonadotropin (hCG), resulting in a pregnancy test strip showing one dark and one faint line.
