A pregnancy test stick with one bar generally indicates that the person is not pregnant.

What does a pregnancy test stick with one bar mean?

If two bars appear on the pregnancy test stick, it may indicate pregnancy. If only one bar appears, it means that the person is not pregnant.

1. Not Pregnant

Only one control line appears, indicating that the person is not pregnant.

2. Pregnant

Two lines appear, both the control line and the test line are colored, and the test line is clearly visible, indicating pregnancy. If the control line is clearly visible but the test line is faintly colored, it may indicate pregnancy. Please use a new pregnancy test stick to collect morning urine for retesting after 2 days.

3. Invalid

If no control line appears within 5 minutes, it indicates that the test is invalid or failed.

It is important to note that when the pregnancy test stick shows "two bars", it does not necessarily mean that the person is pregnant. Besides the presence of human chorionic gonadotropin in urine that can cause two bars on the pregnancy test stick, certain tumor cells or molar pregnancy in women may also cause the pregnancy test stick to show "two bars".

How to interpret the pregnancy test stick?

1. Two red lines on the pregnancy test stick

One line is located in the test area (T) and the other is located in the control area (C). This is a positive result, indicating pregnancy.

2. One red line on the pregnancy test stick

Only one purplish-red band appears in the control area (C), and no purplish-red band appears in the test area (T). This is a negative result, indicating that the person is not pregnant.

3. One deep and one shallow line on the pregnancy test stick

One line is relatively shallow in the test area (T), and the other line is darker in the control area (C). This is a weak positive result, indicating a possibility of pregnancy.

4. No red line on the pregnancy test stick

No purplish-red band appears in the control area (C), indicating incorrect operation or deteriorated reagent strips.

The results of pregnancy tests are not 100% accurate. To confirm pregnancy, it is recommended to undergo blood tests, ultrasound, and other auxiliary examinations at a local hospital. When reading the pregnancy test stick, it is important to clearly identify the control line and test line. If the control line does not appear, it means that the test is invalid or failed.
