Prenatal testing and diagnosis are gaining a strong foothold in a progressively developing country like India, and an estimated boom in the market of noninvasive prenatal testing is predicted by the year 2024. Having said this, every technique needs an adequate amount of supplementation to increase its worth and that is where genetic counseling proves to be indispensable. Postdiagnosis, the women classified as high-risk individuals likely to give birth to infants inflicted with congenital and structural anomalies are appropriately counseled regarding the clinical aspects of the disease, life expectancy associated with the same, and the consequences associated with the decision to go ahead and conceive the child. Genetic counseling is majorly done for Down syndrome as the other aneuploidies have a highly reduced life expectancy. Although there are a variety of techniques available for testing various chromosomal anomalies, information regarding the appropriate time of the test and emphasis on pre- and posttest counseling is usually not supplied to primary physicians. A considerable amount of confusion dominates the decision of which test should be employed for testing of which anomaly as an array of rather efficient techniques has been identified. Furthermore, there is no nation-wide consensus of the timing and nature of these screening protocols. Moreover, ambiguous guidelines along with an impending lacuna in terms of awareness have led to India being at the backseat of the era that has ushered in tons of technological advancement in this field.
