Positive Pregnancy Test
All pregnancy tests function on the principle of detecting a specific hormonal substance in blood or in urine, substance that is present only when the woman is pregnant. This substance, human chorionic gonadotropin, is called the pregnancy hormone.
Types of tests
At present, to find out if they are pregnant or not, many women use a urine test which is quite cheap, easy to handle and can be applied at home, without medical assistance. If the result is positive, you must schedule as soon as possible for a gynecological examination. The doctor will confirm the diagnosis taking a blood test and making a pelvic examination. There are two types of blood tests: one is quantitative - which measures the precise concentration of pregnancy hormone in blood, managing to detect even the smallest quantities of this substance, and the other is qualitative- which gives a simple answer "yes" or "no" to your question, being similar to a urine test, with regards to accuracy.
Blood tests can tell you if you are pregnant in a period of 6-8 days after ovulation and urine tests can detect pregnancy in a period of about two weeks after ovulation. Home pregnancy tests can be bought from pharmacies, but also from many universal shops.
Gynecological exam after positive pregnancy test
The most important step is to be aware of the necessity of a medical consultation. Thus, after you notice that your menstrual cycle is late, it is recommended to take a pregnancy test. However, especially in the case of a positive result, you must go to a gynecologist. On this occasion, the doctor will make an anamnesis (or a medical history): he will ask you about health problems, the family diseases, the sexual and gynecological history, the first periods and their frequency. After he determines the pregnancy and confirms its presence in the uterus, he will ask you to do the following investigations: the Rh blood type, a hemoleucogram, urinalysis, glycemia. These are among others, some of the required analysis and tests that a woman must do in the first semester of pregnancy.
How sure is a pregnancy test? This type of test can be quite accurate, but several factors must be taken into consideration: the density of the urine, the test's brand, how it is used, when it is used, who uses it, etc. The quantity of pregnancy hormone in the urine is different from woman to woman; thus, some women will have a positive result a day after the period's delay, while other women have to wait more. Many pregnancy tests claim that they are 99% sure in detecting the pregnancy a day after the period's delay. But studies show that most of these tests cannot detect pregnancy so early. And when they do it, the results are very doubtful. Most of the tests confirm pregnancy a week after the period's delay or at least 7-10 days after the intercourse.
