问题:
早孕试纸与着床有关系吗

回答:
新颖、方便的早早孕试纸问世后,妇女在家中自测尿液,即可获知自己是否怀孕,确实广受欢迎。那么,该怎样识别早孕试纸呢?

 从妊娠的第7天开始,孕妇的尿液中就能测出一种特异性的js人绒毛膜促性腺js(简称HCG),通常在医院进行的尿妊娠试验检查的就是它。

 目前市售的早早孕试纸,也是通过尿液迅速检测其中的HCG,灵敏度很高。

 在一般情况下,早早孕试纸检测结果有两种:将尿液滴在试纸上的检测孔中,如在试纸的对照区出现一条有色带(有的试纸显红色,有的试纸显蓝色),表示未受孕,反之,如在检测区出现明显的色带,则表示阳性,说明发生妊娠。这种检测具有快速、方便、灵敏、特异性高的优点,可避免与HCG有类似结构的其他糖蛋白js引起交叉反应。但是,自测早早孕的妇女必须记住:早早孕试纸只能作为一种初筛检查。你在试用时要注意以下几个方面:

 1、您购买的试纸如果存放时间过长(1年以上),或试纸受潮,且未注意保存在正常室温条件下(不应冷臧),就可能失效,出现检测结果假阴性。

 2、如果妊娠刚刚开始,或者有异位妊娠(宫外孕)的可能,体内HCG水平一般偏低检测的样品需静置3分钟以上(一般仅需1分钟),并必须仔细辨认是否有弱阳性检测区色带仅隐隐出现。

 3、在极端的情况下,如葡萄胎、绒癌、体内HCG水平会过高,尿液检测反而不显示阳性。

 4、妊娠3个月后,HCG水平下降,尿液检测有时会出现阴性,或弱阳性。

 5、阳性结果也并非意味着百分之百妊娠。因为有些肿瘤细胞如葡萄胎、绒癌、支气管癌和肾癌等,也可分泌HCG。我们还遇到过子宫内膜增生患者出现HCG检测阳性。

 因此,育龄妇女出现停经,不要仅仅依靠一次早早孕纸自测来判断自己是否妊娠。为保险起见,可以在3天后再测一次。当然,最可靠的还是及时到医院进行全面检查,尤其是弱阳性者,以便采取措施。

Question:
Early pregnancy test strip and implantation related to you

answer:
Innovative and user-friendly after the advent of early pregnancy test strip, self-test the urine of women at home, you can learn if they are pregnant, really popular. So, how to identify early pregnancy test strip it?
pregnancy
from the beginning of the 7th day, the urine of pregnant women will be able to detect a specific hormone human chorionic gonadotropin (referred to as HCG), usually in the hospital for urine pregnancy test is it .
At present, the market
early pregnancy test strip, but also through the rapid detection of the urine HCG, high sensitivity.

Under normal circumstances, the early pregnancy strip test results, there are two: The trickle of urine testing in the paper on the hole, as in the control zone in the paper there is a ribbon (marked in red and some paper, some significant blue paper ), indicated that they are not pregnant, on the contrary, as evident in the test area of the ribbon, then positive, that the occurrence of pregnancy. Such testing is fast, convenient, sensitive, highly specific, it can be avoided with a similar structure of HCG glycoprotein hormone caused by other cross-reactive. However, the self-test early pregnancy women must bear in mind: early pregnancy test strip can only be used as a screening examination. When you try to pay attention to the following areas:

1, you buy the paper if stored too long (more than 1 year), or damp paper, and did not pay attention to the preservation of normal room temperature (not cold Zang) may fail false-negative test results occur.

2, if the pregnancy has just begun, or ectopic pregnancy (pregnancy) the possibility of a general low level of in vivo detection of HCG in the sample to be holding more than 3 minutes (usually takes only 1 minute), and must be careful to identify whether there is weakly positive - detection area Ribbon appears only faintly.

3, in extreme cases, such as hydatidiform mole, choriocarcinoma, the body will be too high HCG levels, urine testing but not positive.

4, after 3 months of pregnancy, HCG levels, urine testing is sometimes there will be negative or weakly positive.

5, the positive results of pregnancy does not mean {bfb}. Because some tumor cells such as hydatidiform mole, choriocarcinoma, bronchial cancer and renal cell carcinoma, but also can secrete HCG. We also encountered in patients with endometrial hyperplasia testing positive for HCG.

Therefore, menopausal women of childbearing age appears not to rely solely on a paper early pregnancy to determine whether self-rated pregnancy. For insurance purposes, can be measured in the first three days later. Of course, the most reliable or timely manner to the hospital to conduct a comprehensive inspection, especially in weak positive, to take measures.
