A person can find studies in relation to the testing of Agent Orange on NCBI, CDC and the U.S Department of Veterans Affairs. A study that was done on the health status of 897 U.S. Army Chemical Corps who were exposed to Agent Orange was published by NCBI in 2006.
NCBI, which stands for National Center for Biotechnology Information, concluded that the veterans stood a higher risk of acquiring various diseases such as hypertension and diabetes. The CDC, which stands for Centers for Disease Control and Prevention, and the Department of Veterans Affairs also carried out various studies on Vietnam veterans who were exposed to Agent Orange. The department's study whether there is a connection between hypertension, COPD and other chronic respiratory diseases with Agent Orange is still ongoing as of February, 2015.
