The fact that the menstrual period does not start in the expected period may be an early sign of pregnancy. Delayed menstruation in women who are sexually active requires a pregnancy test.
What are the Pregnancy Test Types? How and when a pregnancy test is done? During this period, various changes occur in the blood circulation of the mother, both in her own hormone table and as the newly formed embryo stimulates the preparation of the environment for attachment. According to the changes that occur, the pregnancy test to be done at the appropriate time will give more accurate results. There are two ways to do a pregnancy test. In both tests, the beta infrastructure of human chorionic gonadotropin (HCG), whose production increases with the implantation of the embryo in the mother's womb, is determined.
This period must pass for the embryo placed in the uterus to attach to the uterus, for the proliferating embryo cells to secrete the pregnancy hormone called "B-hCG hormone" and for this hormone to reach a detectable level in the mother's blood. Pregnancy tests applied before 12 days will show a negative result whether or not a pregnancy has occurred. For this reason, the diagnostic power of early tests by acting impatiently is insufficient.- Urine pregnancy test: It is easy to apply. The result is learned in a few minutes. The result is learned by interpreting the color change of the test strip dipped in urine at home. The presence of two lines in the middle of the bar (plus sign or beep on some test strips) means that the pregnancy test is positive, that is, a pregnancy is present. In order to get a correct result, the expected menstrual date must pass. If the pregnancy hormone that the embryo can produce does not reach the amount that will be released in the urine, it shows a negative result even though there is pregnancy.
- Pregnancy test in blood: reliably indicates positivity from Even if it is done before the expected menstrual date, it gives the result with 97% accuracy. Disadvantage; It should be done under laboratory conditions and by taking blood from a vein. b for the result You may have to wait a few hours. Advantage; It shows the presence of pregnancy 1 week-12 days earlier than the urine test.
What Should the ß-hCG Level Be for a Positive Pregnancy?
- B-hCG hormone level is over 10 in the presence of pregnancy.
- Because the B-hCG hormone level in the blood doubles every two days, the test result can be 50 or even 100.
- However, a positive B-hCG hormone test is not an indication that the pregnancy is intrauterine or healthy.
Where the pregnancy test is (urine or blood) What should be done?
- Pregnancy hormone (β-hCG) starts to rise in the mother's blood first and can be detected in the urine after a while.
- Urine pregnancy tests become positive only after a certain period of time.
- Therefore, if the urine pregnancy test is negative, there is either no pregnancy or the pregnancy is in the very early period.
- If the urine tests are positive, there is pregnancy.
- Blood pregnancy tests are very sensitive.
- In addition, blood tests do not only give results in the form of presence or absence, they also contribute to the determination of the week of pregnancy by giving the numerical value of the hormone level.
Ultrasound Evaluation Pregnancy How long after the test should it be done?
In the early period when the pregnancy test starts to give positive results, the gestational sac is too small to be seen on ultrasound yet. A gestational sac can be detected in the ultrasound evaluation to be performed approximately 10-15 days after the pregnancy test.
What are the Early Signs of Pregnancy in the Mother?
From the first day of pregnancy, an intense preparation begins in the body of the expectant mother. Over time, some symptoms may raise the suspicion of pregnancy. The most common of these are:
- Nausea,
- Inguinal pain,
- Tenderness in the breasts,
- Weakness (or sleepiness),
- Frequent urination.
