The most fundamental mission of Wolfram|Alpha is to be the internet’s hub for all things computable. With this in mind, our medical data team has been combing through peer-reviewed journals, population-based surveys, and credible online health calculators to bring you the most complete, up-to-date, and easy-to-use library of medical calculations available anywhere on the web. This endeavor has been ongoing since the launch of Wolfram|Alpha more than a year ago, and can be demonstrated through queries such as “heart disease risk”, “male age 27, 175 lbs”, or “basal metabolic rate”.

Over the past couple of months, we have worked to implement over 20 new equations. For example, hematocrit levels outside the normal range are indicative of any number of health concerns ranging from dehydration to kidney disease. In circumstances where estimates of hematocrit are in need and only certain parameters are known, Wolfram|Alpha can be used to fill in the gaps and assess whether the estimated value falls within the normal range, given a number of personal attributes such as weight, height, sex, or age:

Calcium in the blood is also a very important indicator of various health conditions, including complications of various types of wounds, hyperparathyroidism, and even osteosclerosis. Given total calcium and serum protein levels, Wolfram|Alpha can estimate the blood concentration of unbound ionized versus protein-bound serum calcium: More »
