The principle of the pregnancy test

Any such test detects the presence of women in the urine of a special hormone HCG. It is human chorionic gonadotropin, which begins to be produced from the beginning of pregnancy, and gradually increase the amount. After attaching to the wall of the ovum in the uterus begins to increase levels of hCG twice every two days to 12 weeks and increasing the maximum. After an abortion or a successful resolution of pregnancy HCG detects its presence in the urine and blood of women within three weeks. This should be considered for women who have come miscarriage, but they hope to save the fetus, or, conversely, are afraid that some of the eggs remain in the uterus.

The time when it is best to test

Time of day when doing a pregnancy test, recommended by the manufacturer. It depends on the type and sensitivity of the test. If you carefully read the instructions that came with the test strips, there is written the time of the. Ink tests marked 10 mIU / ml have a high degree of sensitivity, and time for collection of urine which has no significant difference. After the urine fell on a sensitive part of the strip, the reaction begins, which will result, pregnant women or not.

The day when doing testing

To accurately determine whether a woman is pregnant with the test strips home, need to wait for the first day of the expected menstruation. If the discharge is not started, the first day of delay, you can determine the egg has been fertilized or not.

The sensitivity of the test for the presence of hCG also plays in this process the role. If the counter test strip with a sensitivity of 20-25 MIU / ml, then he can determine the presence of the embryo in the uterus from day delay. More sensitive to 10 mIU / mL, more expensive tests can determine whether a birth, a week after that was going to happen estimated fertilization. If the past week from prospective monthly, which has not started, you can buy any test sensitivity. Its result will be true.

A blood test for hCG a week after the alleged conception for a fee can be made in the antenatal clinic. Testing is carried out in the laboratory IVF clinics, centers for medical diagnostics.

What are the pregnancy tests, and how to use them

In pharmacies, you can buy strip tests or test strips. This is one of the most common tests that women are buying when they need to determine whether fertilization.

The strip is lowered to the desired mark in a jar with a morning urine. Hold there for a few seconds, then pulled out and placed on a flat surface. After a while, you can pick up the strip and look at the result. All types of tests the same principle: one bar - no pregnancy, the two strips - it is. If the test showed a negative result does not dispose of the strip in the bucket. Put it up in the evening on a flat surface. Very often, the reaction is slower than the woman wants, or hCG in the urine is not enough. Practice shows that the second strip may appear in a weak form and later. This means that the pregnancy. When to test again in a week strip will be much brighter.

Tablet tests are arranged on the same principle as the test strip. Their difference is that the test strip is contained in a tablet. For the test in mid-morning urine dripping, and after some time, watching the result.

Ink tests are sensitive tests. They are convenient in that they simply substitute under a stream of urine at any time of day or night, expect a little bit and look at the result.

How to choose a pregnancy test

Selection of the test depends on how many days have passed from the alleged conception and personal experiences. Sometimes a woman in a week after conception knows exactly what she is pregnant. Sometimes it does not know about what happened conception until a missed period she did not tell you that some changes occur to her body. If the delay is large, choose a pharmacy some special test does not make sense. Pregnancy show any of them. If you really want to define, but it took a little more than a week, it is necessary to buy a sensitive pregnancy test and satisfy their curiosity. You can refer to the laboratory and tested for HCG, which will be 100% accurate

Ectopic pregnancy and testing

Ectopic pregnancy is also determined by the test strip. If 7-8 weeks after conception, the woman felt pain in his stomach started bleeding, should immediately call an ambulance. Cheerleaders have pain pulling character and spotting a positive result. It should seek to advance the gynecologist to rule out ectopic pregnancy.
