Wondering if you are pregnant can be nerve-wracking. Knowing ahead of time of what to expect with pregnancy testing can help ease some of your anxiety. Here we provide information on what you can expect for pregnancy testing at your doctor’s office.
There are two main types of pregnancy tests that can let you know if you’re pregnant: urine tests and blood tests. One tests the blood for the pregnancy hormone, hCG. And you need to see a doctor to have a blood test. The other checks the urine for the hCG hormone.
Urine Pregnancy Testing
Doctors can perform urine pregnancy tests (UPT) in their office and is usually the first step in diagnosing a pregnancy. After the urine testing, the doctor can perform even more pregnancy tests such as a blood test and sonogram.
More often, you may take a home pregnancy test (HPT) to quickly determine pregnancy. If a home pregnancy test is positive and you have decided to continue with the pregnancy, you should call us as soon as possible. We can use a more sensitive test such as blood testing along with a pelvic exam to make sure you are pregnant. Seeing us early in your pregnancy will help you and your baby to stay healthy.
If a home pregnancy test is positive and you have decided not to continue with the pregnancy, you should call us as soon as possible. We will do another urine pregnancy testing (UPT) for their records and a sonogram to determine how far your pregnancy has progressed and discuss options that best suit your circumstances.
Blood Pregnancy Testing
Blood tests are done at our office, but are used less often than urine tests. These tests can detect pregnancy earlier than a home pregnancy test, or about six to eight days after ovulation (when an egg is released from the ovary). But with these tests, it takes longer to get the results, usually 2-3 days, than with a urine pregnancy test since they must be sent to a lab.
Two types of blood pregnancy tests are available:
A qualitative blood test simply checks to see if hCG is present. It gives a “yes” or “no” answer. Doctors often order these tests to confirm pregnancy as early as 10 days after a missed period. Some tests can detect hCG much earlier. A qualitative blood test is seldom used to quickly confirm pregnancy since it takes a few days longer. A combination of urine pregnancy test and sonogram which can be performed same day is a good method to detect pregnancy in the doctor’s office.
A quantitative blood test (beta hCG) measures the exact amount of hCG in your blood. It can find even very low levels of hCG. Because this pregnancy test can measure the concentration of hCG, it may be helpful in tracking any problems during pregnancy. The quantitative blood test is often used to rule out a tubal (ectopic) pregnancy or to monitor a woman after a miscarriage when hCG levels fall rapidly.
All pregnancy tests, whether it is EPT, First Response, ClearBlue or at your local doctor’s office, work by detecting a particular hormone in the urine that is only there when a woman is pregnant. This hormone is called human chorionic gonadotropin, or hCG, also called the pregnancy hormone.
hCG is made when a fertilized egg plants itself in the uterus. This happens approximately six days after the egg and sperm unite. But in 10% of women, implantation, when the fertilized egg attaches to the uterus, does not occur until later, after the first day of the missed period. The amount of hCG quickly builds in your body with each day you are pregnant.
The question often arises, what is the difference between a home pregnancy test done at home and a urine pregnancy test performed at a doctor’s office? The difference is not in the test itself but in the ability of the person who reads the test confidently.
A sonogram or ultrasound is a test done during pregnancy that uses reflected sound waves to produce a picture of a fetus. The picture is displayed on a TV screen and may be in black and white or in color. The pictures are also called a sonogram, echogram, or scan, and they may be saved as part of your medical record. Sonogram (sono) can determine the gestational age or estimate age of the fetus. Therefore, it can give you approximately how far you are in your pregnancy; find out if you are pregnant with more than 1 fetus and the gestational age or estimate age of the fetus.
Transvaginal (in the vagina) sonogram is generally done early in a pregnancy to determine fetal age or to detect a suspected ectopic pregnancy.
For a vaginal sonogram, you do not need a full bladder. The vaginal transducer, which resembles a thick wand, is usually covered with a latex sleeve or condom and a vaginal lubricant, such as K-Y Jelly. If you are allergic to latex, tell the health professional before having the test. You will lie on your back with your hips slightly raised. The transducer will be inserted gently into your vagina, and then it will be moved and rotated to adjust the view displayed on the monitor. There is normally no discomfort involved with a vaginal sono. You may feel a light pressure when the transducer is moved in your vagina. And there are no known risks associated with a vaginal sono, either to the mother or fetus.
