To determine the hCG with an ectopic pregnancy will help test

If you think that you have a pregnancy - it is absolutely necessary to contact the doctor. Now there are many different tests that have extremely high sensitivity and give very accurate results. In the case when such a test gives negative results, and you feel all the symptoms of pregnancy - the doctor needs to be treated immediately, since this can be a sign of an ectopic pregnancy.

However, it should be clarified that at the earliest date, ultrasound may not always reveal an ectopic pregnancy. Will the test establish a pathological pregnancy? There are several opinions on this issue.

Any pregnancy test is aimed at finding out in the urine of hCG (human chorionic gonadotropin ) - this hormone is evidence that a pregnancy has come. This hormone is in the placenta, which begins to form, and not in the uterus. Hence, if the pregnancy is (including pathological), the test is obliged to show it. However, using the usual test, you can not find out whether your pregnancy is normal or pathological.

Doctors say that the amount of hCG with ectopic pregnancy is much less than with normal. Therefore, the tests may well not reveal this pregnancy and not show it. So in the absence of menstruation in due time, it is better to visit a gynecologist. The same goes for the situation when the test performed has a positive reaction, but you have bloody spotting . The doctor will assign you a transvaginal ultrasound, which involves the introduction of a vagina sensor. And if there is a need - and the required blood test.

However, there are tests that can not only determine the presence of the fetus, but also recognize ectopic pregnancy or the possibility of spontaneous miscarriage at very early stages. For example, this is the INEXSCREEN test cassette. It is used both for early detection of pregnancy from the very first moment of menstrual cycle delay, and for revealing the probability of development of pathological pregnancy. This test is based on immunochromatographic analysis. What does this mean?

All tests are based on the detection of the amount of the hormone hCG in the female urine. The INEXSCREEN test reveals a correlation of two types of this hormone: intact and modified. In a normally passing pregnancy, about 10% of the modified hormone is present in the hCG structure. The level of hCG in ectopic pregnancy is much lower than 10%, which is considered a diagnostic criterion for the appearance of pathology. This test can be called an innovation, it is quite difficult in terms of science, but in practice it is easily implemented by any woman at home. The only thing to consider is that the detection of a physiological normal pregnancy can be done already from the very first day of the onset of the delay, and the ectopic pregnancy can be determined for 1-2 weeks later.

With regard to reliability, the test for detecting the pathological course of pregnancy is reliable by 90%, and in case of threat of spontaneous abortion - by 65%. Thus, this test is a good indicator of hCG in ectopic pregnancy. For the result of this test to be the most accurate, you need to follow certain rules:

Urine for the test should be applied immediately, because during storage the conversion of hCG during ectopic pregnancy begins from one form to the opposite one, and the test result can not be very reliable.

The unpacked test cassette should be used immediately.

Before the test begins, it is necessary to thoroughly study the test instructions and to decipher the results of the test it must be used.

If you have doubtful symptoms (spotting, pain in the lower abdomen), you should consult your doctor for help, regardless of the results of testing.
