Test identifies any infection from any sample in hours
Scientists from the University of California, San Francisco developed the test, which requires no special handling or processing for each specific bodily fluid and uses next-generation DNA sequencing technology. It accounts for all DNA in a single sample. The test uses a new analytical software application to compare DNA sequences in the sample to genomic databases that cover all bacterial, viral, parasitic, or fungal infections from any species.

Procalcitonin test signals infection in heart attack patients
As an important marker for inflammation in the body, a blood test for PCT is useful for systemic bacterial infections and sepsis. But its value for detecting infection in patients with acute ST-elevation myocardial infarction (STEMI) -- an area of unmet need -- has been unclear. One key question is whether it is specific enough for infection, or whether levels would increase due to cardiac injury -- a limitation of other inflammatory biomarkers such as C-reactive protein (CRP) and white blood cell counts.

Sequencing test spots dangerous infections early in kids with cancer
The prospective study of 47 patients evaluated the sensitivity and specificity of the plasma microbial cell-free DNA sequencing (mcfDNA-seq) Karius test for identifying bloodstream infections three days prior to symptoms. The subjects were younger than 25 with relapsed or refractory leukemia treated at St. Jude Children's Research Hospital in Memphis, TN.
