Early detection of abnormalities helps in ensuring safe pregnancy. PreNatal screening is usually conducted between 11 to 14 gestational weeks. It consists of blood tests and ultrasonography to estimate the risk of chromosomal conditions such as Down’s Syndrome.
Effective testing helps prevent infections during pregnancy. IDT helps in early detection and treatment of infectious diseases such as toxoplasmosis, rubella (German measles), herpes simplex, syphilis, etc. Often, a blood sample is sufficient to carry out this test.
Some abnormalities require an advanced level of screening other than existing screening options. Non-Invasive Prenatal Screening (NIPS) is a genetic test that screens common genetic conditions. It has a high detection rate of 99% for Down’s Syndrome.
