Blood Test for Many Cancer Types as Supplement to Screening
Recent study results from the Annals of Oncology suggest that the Galleri blood test, an assay (a laboratory procedure for assessing or measuring the presence, amount, or activity of a target entity) that can detect up to 50 types of cancers, may become a useful oncology screening procedure.
The Galleri blood test may establish a new method for screening individuals for multiple cancers with a single blood test.
The blood test uses next-generation sequencing (a genetic testing procedure) to analyze the arrangement of circulating cell-free DNA (DNA levels are elevated in cancer) from a blood sample. The Galleri blood test has a cancer specificity detection rate of 99.5% but the overall sensitivity of the test for any stage of cancer was only 51.5%. The Galleri blood test may establish a new method for screening individuals for multiple cancers with a single blood test, in contrast to the traditional clinical scenario wherein only individual cancers are screened. Currently, the test has not been approved by the U.S. Food and Drug Administration and will cost $950.
