July 2025—ARUP Laboratories now provides a blood test for phosphorylated tau 217 to assist in identifying whether symptoms of cognitive decline in patients ages 60 years and older are related to Alzheimer’s disease pathology.
ARUP validated the test using carefully characterized samples from Eli Lilly’s phase three Trailblazer-Alz 2 trial. The validation cohort included blood specimens and results from amyloid positron emission tomography imaging of 524 people.
The test will be performed on Quanterix’s SP-X platform with the Quanterix Simoa assay kit.
