A group of Indian scientists have developed a new device to instantly test hemoglobin in blood.
The device is portable, low-cost, and easy-to- use, and capable of testing hemoglobin from a single drop of blood in less than 30 seconds. In a conventional set up to measure hemoglobin, a clinician is required to draw blood for testing. The sample has to be transported to a lab where test results are accessible to a doctor after almost 4 hours.
With the new device, researchers say, the test can be performed in a clinic itself and results obtained immediately. Hemoglobin testing important to detect anemia particularly during pregnancy as it can increase the risk for preterm delivery. The device can be useful in rural areas where lab facilities may not be available.
