The LDL Cholesterol Calculator, developed by the Ciccarone Center for the Prevention of Cardiovascular Disease at Johns Hopkins, is a free Android application that provides automated calculation of LDL cholesterol levels. This app is based on the method published by Martin and colleagues in the Journal of the American Medical Association, which has been extensively validated and recommended by major clinical guidelines.

To calculate the LDL cholesterol level, the app requires three direct measures from the standard lipid profile: total cholesterol, HDL cholesterol, and triglycerides. Unlike the traditional approach of dividing triglycerides by a fixed factor, the Martin equation used in this app matches each person with a personalized factor.

The LDL Cholesterol Calculator aims to inform users about their LDL cholesterol levels, but it does not replace clinical judgment. The results and recommendations provided by the app should be discussed with a healthcare professional for individualized therapeutic options.

Developed through research by Dr. Seth S. Martin and colleagues at the Johns Hopkins Ciccarone Center, the LDL Cholesterol Calculator is a reliable tool for assessing LDL cholesterol levels. For anyone intending to incorporate this calculator into their services, a license from the Johns Hopkins University is required.
