DIAGNOSTICS : Part 12- 24
From the Desk of Chairman

Prenatal tests are performed to detect abnormal conditions or diagnose disease in the fetus before it is born. These tests are intended to find out traits or characteristics of fetus that may have an adverse effect or threaten the pregnancy. Moreover, some parents are at increased risk of having a baby with certain problems and may like to go in for prenatal tests to know about them before the baby is born. It can help parents make decision about health care for their infant as some of the problem are manageable before birth while others can be administered special attention right after delivery. Again having information in advance would prepare healthcare staff better, and parents for delivery of a child with health problem or for the likelihood of a stillbirth.

Prenatal testing generally determines such defects as neural tube defects, Down syndrome, chromosome abnormalities, genetic disease, and often includes amniocentesis; chorionic villus sampling; single, double, triple screen test; maternal serum screen, and so on. These tests can be non-invasive or invasive.

The Special Feature in the present issue of the WISTA: Diagnostics deals with prenatal diagnosis and gives briefs on the various tests, their implications, risks and benefits. It also covers some recent patents that relate to diagnostic agents for prenatal diagnosis of preterm delivery, fetal infection and fetal damage; methods of detection of genetic disorders; and gene for identifying individuals with familial dysantonomia.

The feature on ‘Trials and Testing’ covers six diagnostic products that are at various stages of testing and development. ‘Patents for 21st Century Applications' lists sixteen recent patents granted around the world.

Other features covered are: Scan Around the Globe; In Focus; Business Trends; Awards; Experts Converge; and Knowledge Spreads.
