A study at the University of Nebraska Medical Center found that a device can significantly reduce the contamination of blood cultures and potentially reduce risky overtreatment and the unnecessary use of antibiotics for many patients.  During a blood draw, skin particles that contain bacteria can lead to false results.  Dr. Mark Rupp is the chief of the UNMC Division of Infectious Diseases and was the lead author of a study on a device called an ISDD

Rupp says those false positive readings in blood tests can cause a lot of problems.

The study shows that using the ISDD reduced the false positive rate by 88%.
