Pregnancy Test Online Free Quiz – The abbreviation hCg stands for human chorionic gonadotropin. This hormone is formed in healthy women during pregnancy in the mother cake (placenta). The hCG concentration increases soon after fertilization in the blood and urine and reaches its maximum between the seventh and twelfth gestation weeks. This hCG reduces the pregnancy test in the urine. For example, the test can be purchased without prescription at the pharmacy. The reliability of such a urine or rapid test is over 95 percent.
What to look for when purchasing the pregnancy test?
The shelf life date must not have expired. Otherwise, the available tests are comparable from one brand to the next, but they differ in their application. Also the time until a result is displayed and the representation of the result can vary: Therefore, always read the instructions carefully when testing a new brand!
How does a conventional pregnancy self-test proceed?
The usual pregnancy tests refer to pregnancy from two weeks after the fertilization of the ice or from the first day of the missing menstruation. The hCG contained in the urine triggers a chemical reaction with the enzymes present on the test strip. To do this, hold the test strip in the urine stream. The morning urine is most suitable, because the hCG enriches itself overnight. According to the hCG content, a discolouration results in the result window. Most common: two strips = pregnant, one strip = not pregnant. Please note when reading the time window, when the result is displayed reliably and how long: in some tests, the display will be inaccurate after an hour.
Especially in the first days of pregnancy, drinking large amounts of fluid before the test can lead to a negative result even though a pregnancy exists. This dilutes the concentration of hCG in the urine so that it does not reach the necessary threshold value for a positive test result.

What methods do pregnancies show earlier?
Early tests use so-called immunochromatography with antibodies against hCG. They are able to detect even the smallest amounts of hCG in the urine four days before the absence of the monthly hemorrhage, but the error rates are correspondingly high. The female doctor can also determine the pregnancy by means of a blood test, already six to nine days after the fertilization of the fertilized ice. The laboratory also determines the exact concentration of hCG in the blood. This allows conclusions to be drawn about the time of fertilization: the hCG values ??initially double about every 2.5 days until they settle at their maximum of approximately 45,000 international units / liter.
The determination of the hCG can also be useful in the further course of the pregnancy, for example, if the suspicion of an abortion or an ileitis pregnancy is given.
How much does a pregnancy test cost?
Pregnancy tests already exist at around four euros. A little more cost digital tests, which display the result in written form.
When should a positive pregnancy test go to the doctor?
If the test result is positive, the Federal Institute for Risk Assessment (BfR) recommends the use of folic acid and iodine. Before taking the medicine, the mother should consult the physician, as, for example, certain thyroid diseases may be a counter-indication of an iodine intake. Combination preparations with iodine and folic acid are available at the pharmacy. (Note: BfR recommends that an adequate supply of iodine and folic acid should already be taken when a pregnancy is desired. An additional supply of folic acid should commence no later than four weeks before the planned conception, according to BfR.) In order not to jeopardize life, Avoid alcohol and smoking as much as possible.
Despite the fairly high reliability, the mother should seek a female doctor after a positive pregnancy test in order to confirm the results and to carry out the pregnancy care. If symptoms such as bleeding from the vagina or pelvic pain are present, a timely appointment is recommended. Likewise with chronic illnesses with medication intake. In the case of freedom from complaints, however, it is generally sufficient to present oneself within the next one to two weeks. In addition to blood and urine tests, the doctor can also use ultrasound as an optical detection device.
