'University of California at San Francisco biochemist Dr. Joe DeRisi developed the revolutionary ViroChip, which tests for all known animal and human viruses'. This test is done once with just one blood sample ! This is amazing, saves me so much time and money. Apparently cfs-ers usually have about 30-40 ongoing infections at the sametime while normal pple have only about 3-4. Does anybody know how one can test for this ? Thank you !!
