If a woman does a pregnancy test Pregnancy tests - early diagnosis , It should be understood that the information content of the urinary test depends on when it was made. Not at all stages of pregnancy, he has an equal diagnostic value. The question of when to do a pregnancy test, you must go to a specialist, the physician will be able to explain to the woman all the points related to the test. The correct approach is when a woman visits a doctor first, and then do the test. In everyday practice, the opposite situation occurs.

What to diagnose pregnancy

Currently, there is one of the easiest and affordable methods of diagnosis of pregnancy - urinary test. It depends on the ability of a test system responsive to the presence of the hormone in the body, which can be produced only in the presence of pregnancy (chorionic gonadotropin hormone, or hCG). Test strips coated with specific reagent, which in the presence of the hormone in the urine color changes.

Since egg fertilization before entering into the uterus takes an average of five to six days. Once implantation has occurred, the future placental cells begin to produce the hormone hCG. In the blood, this hormone can be detected by a blood test in the seventh, the ninth day after conception Conception - as the emerging life . In urine it is diagnosed later. As gestational age increases, there is an increase of concentration of the hormone in women. Knowing these nuances can properly diagnose pregnancy using urine test. If women do not have regular menstruation delay, the descriptiveness of the urinary test is the lowest, and to do it does not make sense.

Optimal timing of the urine test

The most important point for urinary test is the presence of the delay. Do not do the test, when the delay is only one or two days. You have to wait for a week and then do the test. On a very small stage of pregnancy at a delay of one day urine test does not have diagnostic value. If there is a need to establish a pregnancy in this period, it is necessary to determine the content of the hormone hCG in the blood as urine analysis is informative. Urinary test is best done under the following conditions:

• the presence of a delay for at least five days;
• if there is a delay of one or two days, the test should be repeated after a week. In this case it is possible to obtain the most correct result given the fact that the body of the pregnant woman will increase the content of HCG hormone;

Since the concentration of the hormone has a tendency to steady growth almost to the end of the first trimester (up to ten weeks), it helps in carrying out the dynamic control of pregnancy. If a woman is made of uric test with a small delay, or even prior to the expected menstrual period, the repeated carrying out the test only allows you to find out the fact of pregnancy, but does not allow for quantitative control of the hormone hCG and assess its growth dynamics.

Of great importance is holding a urinary test to exclude ectopic pregnancy or ectopic. If the doctor suspects a woman's development of the ovum outside the uterus, it is necessary to make one of the most accessible diagnostic tests - urine. In this situation, a positive pregnancy test Positive pregnancy test: how to evaluate the results   It will be the signal for further, more in-depth survey tool woman. If during the test is weakly positive study (clearly expressed the second band), it may also be a confirmation of the pregnancy, so women should be examined in its entirety, so as not to miss the fact of complicated pregnancy. In doubtful cases it is better to make a blood sample and determine the level of hCG in the blood of women that will already be a confirmation of pregnancy. In the future, we will need to determine where it develops in the uterus or outside.
