chorionic , auch: choroidal

Chorionic villi cells can be collected in one of two ways.

See, the normal rabbit test is chorionic gonadotrophin in urine.

It is probably not the human chorionic gonadotropin itself that causes the nausea.

The first test, called chorionic villus sampling, is offered at about 9 to 11 weeks of pregnancy.

With chorionic villus sampling, the cells can be analyzed immediately.

You would need a diagnostic test, such as a chorionic villus sampling, to find out if there is a problem.

This process may take about four months and can be monitored by checking human chorionic gonadotropin levels.

A major question has been the comparative safety for the fetus of the chorionic test and amniocentesis.

Meanwhile, some doctors began offering chorionic villus sampling later in a pregnancy.

Diagnosis is made in the first trimester by chorionic villus sampling.

Eventually, the syncytiotrophoblasts come into contact with maternal blood and form chorionic villi.

Chorionic villi are a rich source of stem cells.

The chorionic villi create a large surface to maximize the exchange that takes place between the two blood supplies.

Because early amniocentesis and late chorionic sampling are so new, there are no studies on their safety.

Women had to have a negative result on a test of serum beta human chorionic gonadotropin at screening.

To perform the genetic test chorionic villous sampling, or to obtain a blood sample from the baby.

Some of the chorionic villi will now disappear, leaving others to grow and become the placenta.

Amniocentesis or chorionic villus sampling can be used to screen for the disease before birth.

Human chorionic gonadotropin is an autocrine growth factor for the blastocyst.

Mammals do not necessarily have the same human chorionic gonadotropin released from their embryo.

Antibodies raised against human chorionic gonadotropin are used in over the counter pregnancy tests.

Within the next nine months, the investigators hope to have enough data to determine whether the chorionic test is as safe as amniocentesis.

He said it began when women would come in just after the period when chorionic villus sampling normally is used.

The chorionic villus cells are checked for problems.

It is done by evaluating cells from chorionic villus sampling or amniocentesis.
