Amniocentesis is a test during pregnancy that removes a small amount of fluid from the sac around the baby to look for birth defects and chromosome problems.
|
 |
Amniocentesis is a procedure used to diagnose fetal defects in the early second trimester of pregnancy . A sample of the amniotic fluid, which surrounds a fetus in the womb, is collected through a pregnant woman ' s abdomen using a needle and syringe.
|
|
First, the fetus is located with ultrasound. A thin needle is then inserted into your belly. The doctor keeps the needle from touching the fetus by watching the screen.
|
 |
Amniocentesis is an optional procedure offered to women during pregnancy in order to obtain more information about a developing fetus. A doctor uses a thin, hollow needle to remove a small sample of amniotic fluid from around the developing baby.

|
 |
Amniocentesis is an optional but reliable procedure offered to pregnant women in order to obtain more information about a developing fetus in the second trimester of pregnancy . It is primarily offered to pregnant women who are at increased risk, based on their age, family history, or other factor, of having a child with a genetic condition.

|
|
A medical test that involves withdrawing a sample of fluid from the amniotic sac surrounding the fetus in the abdomen of the pregnant woman. Amniocentesis is a procedure used to detect the presence of genetic disorders such as Down syndrome and spina bifida in a fetus.

Blood pressure measurement is the non-invasive measurement of the pressure exerted by the circulating blood on the walls of the body ' s arteries. Purpose The purpose of non-invasive blood pressure measurement is to detect any changes from normal values, which may indicate disease.
|
|
A review of the methods and technology available for home monitoring, which can be an important aid to lowering your blood pressure.
|
 |
Measurement of the pressure exerted by the circulating blood on the walls of the blood vessels , especially the arteries. Purpose The purpose of blood pressure measurement is to establish a baseline and detect any abnormalities from the normal state.
|
|
Did you know you can purchase your own blood pressure monitor and check the reading yourself at home?
|
|
You can take your own blood pressure reading using a digital monitor.

Echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than x-ray image and involves no radiation exposure.
|
 |
Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart ' s valves and chambers as well as the flow of blood through the heart.

|
|
An echocardiogram (echo) is an imaging test. It helps your doctor evaluate your heart. Here is how it works.
|
|
Echocardiography is a diagnostic test that uses ultrasound waves to produce an image of the heart muscle and the heart ' s valves. Purpose Echocardiography is used to diagnose certain cardiovascular diseases, and is one of the most widely used diagnostic tests for heart disease.

Chorionic villus sampling (CVS) is the removal of a small piece of placenta tissue (chorionic villi) from the uterus during early pregnancy to screen the baby for genetic defects.
|
|
Chorionic villus sampling (CVS) is a prenatal procedure for the removal by needle of chorionic villi and culture and examination of the fetal cells obtained. The cells are used in tests for genetic and chromosomal abnormalities of a fetus as early as 10 to 12 weeks of gestation.
|
|
Detailed information on chorionic villus sampling, including potential risks and benefits
|
 |
Chorionic villus sampling (CVS), also known as chorionic villus biopsy, is a prenatal test that can detect genetic and chromosomal abnormalities of an unborn baby. Purpose Chorionic villus sampling is performed on pregnant women who are at risk for carrying a fetus with a genetic or chromosomal defect.
|
|
CVS is a test that helps you learn if a fetus has health problems. The test is most often done between weeks 9 and 11 of pregnancy.
|
|
Fluorescent in situ hybridization (FISH) is a powerful technique used to identify the presence of specific chromosomes or parts of chromosomes through the attachment (hybridization) of fluorescent DNA probes to available chromosomal DNA. The fluorescent DNA sequence used to attach to the cellular DNA is called the probe and is created in the experimental laboratory.

Detailed information on what type of testing is available to determine whether a child has a genetic birth defect
|
|
During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

Serum calcium is a laboratory test to measure the amount of calcium in your blood. All cells need calcium in order to work. Calcium helps build strong bones and teeth. It is important for heart function, and helps with muscle contraction, nerve signaling, and blood clotting. Calcium can also be measured in the urine. See: Calcium - urine test
