Complimentary Prescreen for Obesity and Weight Loss Research Studies

Obesity is upstream of many other conditions including those affecting the heart, liver, kidneys, and more. These assessments may lead to discovery of other study opportunities you may qualify for, including others that utilize the same investigative product that is tested for weight loss.

Are you overweight?

Do you have Type II Diabetes?

Do you have high Cholesterol?

You may be suffering from Fatty Liver Disease!

If you want to know how healthy your liver is, come get your FREE liver scan with the McAllen Research Healthy Liver Program.

The McAllen Research Healthy Liver Program is a free, public health service dedicated to the early detection and prevention of fatty liver disease. Fatty liver disease may lead to nonalcoholic steatohepatitis, which is the fastest rising cause of cirrhosis or liver damage among Latinos.

We also offer FREE, non-invasive liver test called Fibroscan for all patients along with other ongoing studies.
