If you have experienced a pregnancy loss, you have probably asked “Why did this happen?” and “Could it happen again?” Here you will learn about a test that can provide some answers about one of the most common causes of pregnancy loss.
What causes a miscarriage?
Spontaneous pregnancy loss happens more frequently than you might think. In fact, it occurs in 15-20% of pregnancies where the woman knows that she is pregnant. Most miscarriages occur during the first seven weeks of gestation, and although there are many different causes for pregnancy loss, the most common is a chromosomal abnormality in the fetus, which can prevent the baby from growing properly. Chromosomal abnormalities account for more than half of all miscarriages.
A chromosomal abnormality is not caused by anything that you did or didn’t do either before or during the pregnancy. Most chromosomal abnormalities happen by chance, and the risk of a chromosome problem happening again in a subsequent pregnancy is low.
What is Chromosomal Microarray Analysis for Pregnancy Loss?
Find answers about the causes of pregnancy loss.There are several genetic tests that can be performed on fetal tissue after a miscarriage to help understand if the spontaneous pregnancy loss occurred as a result of chromosomal changes. Chromosomal Microarray Analysis is a comprehensive genetic test that can detect both large and small changes in chromosomes.
Chromosome analysis can be especially important for patients who experience repeated miscarriages. The test results can either help reveal an underlying genetic cause of spontaneous pregnancy loss, or rule out chromosomal errors, which allows you and your doctor to pursue other types of testing.
When can Chromosomal Microarray Analysis be performed?
The test is usually performed at the time of spontaneous pregnancy loss, after a D&C procedure or after home collection of miscarried tissue.
