The presence of two bars on the morning pregnancy test paper or pregnancy test stick is not necessarily pregnancy, there may be a false positive result, or there may be some pathologic factors that cause HCG elevation. Using pregnancy test paper or pregnancy test stick to test urine is a common clinical method to detect early pregnancy. If there are two bars, it can only say that there is a higher chance of pregnancy, but it is not certain that you are pregnant. The accuracy of early pregnancy test paper or pregnancy test stick is not 100%, sometimes there may be false negative or false positive results, or even invalid results. Therefore, if there are two bars, it is recommended to take a blood test for HCG, which can determine whether you are pregnant or not. If a woman has some gynecological malignant tumors, such as trophoblastic tumors, the urine test with early pregnancy test paper may show positive results.
