Prenatal Diagnosis Center and what we do


We are a group of Doctors and Professionals providing sensitive and non-intrusive care. Innovation is the cornerstone of what we do and we strive to be on the cutting edge of technology in order to provide those answers.

Dr Thiagarajah is widely published in his field and is considered an expert in the care and management of high risk pregnancies. Under his expert guidance, The Prenatal Diagnosis Center offers the earliest screening available for Down Syndrome and other abnormalities in an unborn baby. They perform first trimester screenings between 11 and 14 weeks of gestation. The screening will detect up to 95 percent of Down syndrome and other chromosome abnormalities. Dr Thiagarajah  also perform second trimester ultrasounds, preferably at about 22 weeks’ gestation, to evaluate for fetal structural abnormalities. Abnormalities of the fetal heart are among the most commonly encountered in prenatal diagnosis. Those who are at increased risk for a heart abnormality, such as diabetic mothers, those with a previous child with a heart defect, those with a family history of congenital heart disease or if they themselves have a heart defect and exposure to certain medications, can have a detailed evaluation of their baby’s heart (echocardiogram) at 22 weeks gestation. Some fetal abnormalities such as cleft lip are best illustrated using the new 3-D ultrasound technology available at their office. 



Genetic Counseling plays an important role

Couples referred to the Prenatal Diagnosis Center may receive genetic counseling. Genetic counselors are trained in clinical genetics and counseling and they have a Masters Degree in Genetic Counseling and extensive experience in providing information regarding various genetic disorders.  They are also trained in assisting with the care of individuals carrying a pregnancy affected by a birth defect as well as those at risk of a having a pregnancy with a birth defect or genetic disorder.

Prior to their scheduled ultrasound procedure, they meet with couples who are at increased risk for fetal chromosomal and structural abnormalities to further explain and clarify those risks. They take a detailed family and medical history and discuss the ultrasound examination and other possible tests. They will also discuss abnormal results and options available to the families.
