A team from the Indian Institute of Technology Madras (IIT-Madras) has created a groundbreaking test designed to detect pre-eclampsia in pregnant women. This simple and portable device can identify the condition in just 30 minutes using a tiny drop of blood.
Pre-eclampsia is a serious pregnancy complication that usually occurs after the 20th week of pregnancy. It is characterized by high blood pressure and can lead to severe health issues for both mothers and their babies. Globally, it affects 2 to 8 percent of pregnancies and can result in approximately 46,000 maternal deaths and about 500,000 fetal or newborn deaths each year, according to the World Health Organization.
The new test, developed by Professor V. V. Raghavendra Sai and Dr. Ratan Kumar Chaudhary, uses advanced fiber optic technology to measure levels of a protein called placental growth factor (PlGF). This biomarker is crucial for diagnosing pre-eclampsia before it becomes life-threatening.
The technology is designed to be user-friendly and cost-effective. Traditional methods for detecting pre-eclampsia often require complicated and expensive laboratory equipment, making it difficult for women, especially in rural or underserved areas, to receive timely care. The IIT Madras device is palm-sized and can be easily used in a clinic without needing large machines or long wait times for results.
“Early detection of pre-eclampsia is vital, as timely treatment can reduce the risk of severe health complications for both mothers and infants,” said a spokesperson from the research team. The device has successfully passed several validation stages, including clinical evaluations, paving the way for its potential commercialization.
Not only is this development significant for managing pregnancy-related health, but the technology also holds promise for detecting other diseases, including cancers and tuberculosis. This versatility underscores the innovation’s potential to enhance healthcare in regions lacking adequate medical resources.
The research findings have been published in the journal Biosensors and Bioelectronics, marking a significant advancement in prenatal care and offering hope for better health outcomes for mothers and babies everywhere.
