Pregnancy test: An attempt to determine whether a woman is pregnant or not
Reasons for testing
We conduct pregnancy testing in the following cases:
- Know the presence or absence of pregnancy.
- Diagnosis of some abnormal conditions that may raise levels of human gonadotropin (HCG) in blood and urine, such as benign and malignant placenta.
- Monitoring pregnancy progress during the first three months of pregnancy (quantitative testing only);
- Quantitative testing is used for part of the Down Syndrome screening tests.
- The test may be required regularly to monitor the efficacy of treatment in some cases and to detect the recurrence of related tumors.
- The pregnancy test is performed ten days after the absence of the menstrual cycle in the woman (although
There are tests that can detect the pregnancy before, about a week after fertilization), or when the doctor believes that the symptoms in the woman suggest ectopic pregnancy, placenta, or germ cell tumors (benign tumors) And malignant), in the testis in males or ovaries in females.
And laboratory blood tests
To find out pregnancy can detect the hormone with an accuracy of 100% and early can be up to 7 days after pregnancy and also helps this test that determines the date of pregnancy by measuring the amount of the hormone.
Blood test and quantity, usually called beta-hcg, means that even the minimum level will be detected the most. Another type of blood test is sometimes called human chorionic gonadotropin (hcG). This is a test that just gives a yes or no answer on whether you are pregnant.
No matter what the results of laboratory tests, the most accurate diagnosis requires a medical examination also because the arrival of negative results wrong is not excluded at times, especially at the beginning of pregnancy. The test and medical examination should be repeated approximately one week later. If the results of pregnancy are repeated negative as the menopause continues, the woman must present the order to the doctor in order to exclude an ectopic pregnancy.
Blood pregnancy analysis takes from one to two hours
