Rosalynn Yalow

Rosalynn Yalow was an American medical physicist who won the Nobel Prize in Physiology or Medicine in 1977 for developing a method to measure tiny amounts of hormones and other chemicals in the blood. Her technique, called immunoassay, allows doctors to diagnose and monitor diseases like diabetes more accurately. Yalow’s work revolutionized medical testing by enabling precise and early detection of health conditions. Her contributions significantly advanced medical science and improved patient care, making her one of the most influential scientists in the field of clinical diagnostics.
