Pregnancy diagnostic.
Menstruation delay is usually caused by pregnancy. If menstruation didn’t come on the day then beginning from the next morning you may take temperature in the gut rectum. Usual clinical thermometer is led into the gut rectum on the 2 cm deep for 5-7 minutes after the wake-up and you don t have to get up. If basal temperature is more than 37 degrees in stability that can affirm possible pregnancy. However the lower temperature indicators can be met too especially with spontaneous pregnancy interruption threat.
If there is a menstruation delay of 1-2 days and more you may use early diagnostic pregnancy test. (most of tests on sale today determine pregnancy on the first day of menstruation delay) It s simple in use and reliable enough. The result exaction will be higher if to do examinations 2-3 times. The principal work of the tests is: when it contacts the pregnant woman urine two transverse lines have to appear on it. First is a control line meaning that test is OK and the second - affirming about existence of Chorionical Gonadotropine (CG) and that says about woman pregnancy. If there is not - no pregnancy.
In spite of the external distinctions of the tests there is a reaction on specific hormone in the basis of the effect (CG) which begins to produce in the woman organism and the disintegration products. Hormone and disintegration products are exuded with urine. And the chemical reactive by which the plate is saturated interacts with them. It is better to take the morning urine portion for examination. The problems come just when one or two lines become pale eroded and hardly readable. It s better to buy a new test in this situation. And much better to buy a *streaming test*. It costs more expensive but more reliable than line-tests. Talking about better time for testing++it s often written in the instructions that tests work already on the 7th day after conception which usually happens in the middle of the cycle. We do not think it is true because the CG level is not big enough this time. It is better to use test when the critical days had to begin. In case of this the result is usually exact.
More difficult and at the same time more reliable methods of pregnancy determination are based on the taking the hormone level in the woman organism by the laboratory way. You hand over blood from your vein and get your result in the some time. In that case more specific hormone level is determined - The Trofoblastic B - Globulin which gives more reliable information and first of all about hypothetical pregnancy period. The laboratory method is much more reliable though it takes more time.
The one reliable method of pregnancy determination is the ultra-sound research (USR) of small pelvis organs. Depending on the research methodic it can be Tran abdominal ( means through the straight peritoneum wall) and Tran vaginal ( when sensor is led into the vagina) moreover the last variety gives more information. But using these methods it s possible to get information about pregnancy existence and its localization beginning from 2.5-3 weeks period.
Some time passed by from the beginning of menstruation delay, you feel yourself good, the pregnancy test gives the plus-result. Should you go to gynecologist? - Yes, you should. First of all to make sure that pregnancy is uterine.
Tests and analysis for early pregnancy diagnostic give the same result when pregnancy is uterine or non-uterine. That s because the fertilization happens out of the uterus cavity and the fertilized egg-cell has to get the implantation place through the uterine tube. And if on the way of the egg there are the barriers like contractions in the uterine tube or the fertilized egg-cell moves through the uterine tube too long time and fetus is too big for the uterine tube gap it does not get into the uterus cavity. The echoscope or non uterine pregnancy happens. That s why if you have even little doubts do all tests and analysis for early determination of pregnancy and visit your gynecologist if the result is affirmative. If the pregnancy test gives negative result and the menstruation delay goes on visit gynecologist - endocrinologist to know the reasons of the menstruation cycle disfunction.
