Biomarkers assist healthcare suppliers establish, monitor and decide threat for illness — together with coronary heart illness, the main reason for dying for ladies within the U.S.
Biomarkers additionally play a giant function within the improvement of medicines and therapy choices for well being circumstances akin to most cancers. Right here’s extra on the fascinating world of biomarkers, and what it is advisable learn about biomarker testing.
What’s a biomarker?
A biomarker is a organic substance or signal that may be measured to judge well being and illness. Biomarkers will be molecules, proteins, genes and different traits present in blood, physique fluids or tissue.
One instance of a biomarker is blood glucose (sugar). Excessive or fluctuating blood sugar ranges is an indication of diabetes. A healthcare supplier can use the blood sugar ranges to maneuver ahead with a prognosis and the most effective therapy plan to handle the situation.
