The Galleri\u00ae multi-cancer early detection test<\/h2>\n
\n

Cancer screening saves lives, but 70% of cancer deaths are caused by cancers without recommended screening tests.*1,2<\/sup> The Galleri<\/a>\u00a0multi-cancer early detection (MCED) test can help find these cancers. With a simple blood draw, Galleri can detect more than 50 types of cancer before symptoms appear \u2014 when they can be easier to treat and are potentially curable.3<\/sup><\/p>\n

The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood. False positive and false negative results do occur.<\/sup><\/span><\/p>\n

The Galleri test increases the number of cancers detected seven-fold when added to standard of care screening for breast, cervical, colorectal, and lung cancers and has the lowest false positive rate of any MCED test**.3,4,5,6<\/sup><\/p>\n

The test is especially sensitive to many of the deadliest cancers that are typically caught too late \u2014 like pancreatic, liver, and ovarian*** \u2014 and about half of Galleri-detected cancers are found at an early stage.3,6<\/sup><\/p>\n

The Galleri test identifies DNA in the bloodstream shed by cancer cells and does not predict future genetic risk for cancer.<\/sup><\/p>\n <\/div>\n Visit Galleri site<\/span>Visit Galleri site<\/span><\/a> <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n\n\n

The Galleri test delivers results you can trust <\/div>\n

People who don\u2019t have cancer have a very low likelihood of receiving a Cancer Signal Detected test result with Galleri. Galleri has a false positive rate of just 0.4%\u2014 the lowest of any available MCED test ** \u2014 helping to minimize unnecessary procedures and exposure to radiation.3,6<\/sup><\/p>\n

People who receive a Cancer Signal Detected test result with Galleri have a high likelihood of having cancer (positive predictive value of approximately 62%).3,4,6<\/sup><\/p>\n

Galleri is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer. The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood. False positive and false negative results do occur.<\/sup><\/p>\n

The Galleri test predicts a cancer signal of origin with more than 94.3% accuracy, guiding an efficient diagnostic work-up.6,7,8<\/sup><\/p>\n

Galleri screening is a game changer for cancer detection, helping adults at elevated risk of cancer, such as those 50 and over, detect aggressive cancers earlier and giving them more control over their health.<\/p>\n
