What assurance do I have that the unit of blood I receive did not come from a donor with an undiagnosed case of West Nile virus?
Community Blood Center, which provides blood for more than 70 hospitals in Lawrence, Topeka and the Kansas City area, tests for West Nile virus infection in the blood it receives and distributes.
The center is one of 30 U.S. labs to use nucleic acid amplification testing to check the national blood supply for the virus, center officials said. Such testing is considered the most sophisticated method available for detecting West Nile virus.
The center has conducted more than 44,000 such tests since July 1.
