From the beginning of the 7th day of pregnancy, in the urine of pregnant women will be able to detect a specific hormone-human chorionic gonadotropin (HCG for short), usually in the hospital for urine pregnancy test is it. Currently sold in early pregnancy test strip or very early pregnancy test strip is also determined by rapid detection of HCG in urine pregnancy or not.

In the General case, there are two kinds of results in detection of early pregnancy test strip: detection of urine drop in paper in the hole, as in the control region appears as a colored ribbon of paper (paper red, some paper blue), negative, has not been pregnant, conversely, as in the detection area markedly ribbons, the positive, have been pregnant.

2, if the pregnancy is just beginning, or such as ectopic pregnancy, ectopic pregnancy, HCG levels in the low, detection of urine aside 3 minutes more (typically takes only 1 minute), you must carefully identify whether there is a weak positive-detection-area band loomed only.

3, in exceptional circumstances, such as hydatidiform mole, choriocarcinoma, is high HCG levels in urine detection instead of the positive.

4, after 3 months of pregnancy, HCG levels, urine testing sometimes appear negative, or weak-positive.

5, positive results are not necessarily the pregnancy. Because in addition to pregnancy to nourish somatic cells to secrete HCG, some tumor cells such as Mole, choriocarcinoma, bronchial carcinoma and renal cell carcinoma, or secretion of HCG.
