What is Non Invasive Prenatal Test (NIPT)?
Non-Invasive Prenatal Test (NIPT), also known as non-invasive prenatal screening is a highly accurate test that is conducted to determine if your baby is at risk for genetic abnormalities such as Down syndrome, Edwards syndrome, and Patau syndromeas early as 10th week of gestation. This test is done by screening a blood sample from the mother to pinpoint the baby’s risk for disorders and chromosomal abnormalities.
During pregnancy, tiny pieces of cell-free DNA (known as fetus’ DNA) passes into the mother’s bloodstream. The non-invasive prenatal test analyzes the cell-free DNA to obtain information about the genetic health of your developing baby. This test can also reveal the sex of your baby in the first trimester. This test is considered noninvasive as it utilizes a blood sample from the mother and does not pose any risk to the fetus.
This test is very accurate, especially in determining cases of Down syndrome. It can also predict whether the risk of genetic disorders is high or low. However, Non-Invasive Prenatal Test is still a screening test—not a diagnostic test. This means that it can only determine if there’s an increased risk for a genetic condition, but it cannot diagnose a genetic condition with certainty.
How non-invasive prenatal test is done?
This test doesn’t involve any complicated procedures. Maternal blood is drawn by a phlebotomist and sent to a specific lab where it will be analyzed for results. Once the results have been obtained, they will be sent to your doctor. It usually takes 10-14 days to get the results of your NIPT. The doctor may pair them with the results of your first trimester to determine whether further testing is needed.
Who should get a non-invasive prenatal test?
This test is recommended for persons with risk factors for certain genetic conditions. This may include persons with a family history of chromosomal abnormality and those aged 35 or older at delivery. It may also be recommended for a person who has had a baby previously with a chromosomal condition.
How much does the non-invasive prenatal test cost?
Typically, the cost of NIPT ranges from PHP 21,500-P38,500. However, this may vary depending on where the test is performed.
If you’re considering getting a non-invasive prenatal test, you should first consult with your doctor.
