Two bars means pregnancy?

The pregnancy test strip is used to test the early stage of pregnancy after the embryo has successfully implanted. In the displayed result, one bar means no pregnancy, which is negative, but two bars are positive, indicating pregnancy. Since the pregnancy test strip reflects pregnancy based on the reaction of the test reagent to urine, some deviations are inevitable. So, does two bars mean pregnancy?

Does two bars mean pregnancy ?

1. Symptom signs: In addition to the influence of HCG produced by pregnancy, some tumors such as choriocarcinoma, bronchial cancer and renal cancer, as well as hydatidiform mole can also secrete HCG if there are "two bars" on the pregnancy test stick.

2. If the pregnancy test stick expires or is not stored properly, resulting in moisture and a positive result, it will appear as "two bars". Otherwise, the pregnancy test stick will only have one green line. Comparison line C shows that there is no dark purple band in the test area T, which is interpreted as a negative result, generally indicating no pregnancy. If there is display information in the only detection area T, but no display information in the comparison line C, the result is invalid and cannot be used as a basis for distinguishing whether the woman is pregnant.

3. Generally, pregnancy test sticks will display data regardless of whether the result is accurate or not. However, if there is still no response within five minutes of using the pregnancy test stick, it means that you have been operating it improperly during the use process, or there is a problem with the quality of the pregnancy test stick itself. Therefore, no data is displayed, which means that this pregnancy test is invalid or unsuccessful.

Reasons for a weak positive pregnancy test stick

1. There is too little HCG in the early stages of pregnancy. The key to detecting pregnancy with a pregnancy test stick is to accurately measure the component of human chorionic gonadotropin (commonly known as HCG) in urine.

2. "Ectopic pregnancy" causes a slightly low HCG value. If the pregnancy test stick is used for pregnancy testing after the menstrual period is delayed for a long time, but the data of "one deep and one shallow" still appear, you need to be alert to the possibility of ectopic pregnancy.

3. There is a possibility of "ectopic pregnancy". If the pregnancy test stick shows one dark and one shallow color, and no test results are found in the next few days, it may be an ectopic pregnancy. To put it simply, advanced pregnancy refers to the fusion of sperm and egg. The trophoblast layer can produce a small amount of HCG, but the test tube embryo does not continue to grow normally afterwards, that is, the fertilized tube embryo fails to implant, resulting in results from "one deep and one shallow" to "undetectable". In fact, this is not a successful pregnancy.

The two bars on the pregnancy test stick are partly caused by the cause of pregnancy, but partly are the result of other diseases in the human body. Therefore, in addition to the pregnancy test stick, you need to go to the hospital and communicate with the doctor to conduct other relevant tests to confirm the cause. Treat related diseases promptly to avoid delays in treatment and threats to your health.
