Researchers Demonstrate Value for the First Genetic Test for High Blood Pressure and Sensitivity to Salt

Two genes at most were necessary to predict with a 78 percent accuracy which people with high blood pressure (hypertension) had a low renin levels, a substance that is currently measured to help establish the diagnosis of salt (sodium chloride) sensitivity. Thus, the researchers found different genetic bases for low renin in the blood and for salt sensitivity. Salt sensitivity is defined as a greater than 10 percent increase in blood pressure following a high-salt meal.
