This data was expected for this visit. Core Analytes were expected of CT participants in the blood subsample at baseline and at years 1, 3, and 6.  Core Analytes were expected  for OS participants in the OS Measurement Precision Study (OS-MPS) at baseline and at a non-routine visit between 1 and 180 days after enrollment.

Unique identifier of the test name and test version.

Number of days from date of specimen draw to when the specimen was sent to the lab for testing.

The id of the study pull responsible for the test result. Pull ids are in the form xxx-yyy where xxx is the study id.

A new version number is assigned for every change in lab, specimen type, units or method. e.g. if we have results from two different labs for a glucose assay, each would get its own version number. GLUC V1 & GLUC V2.

The median of TESTVAL in specimen results file (spec_results) for this test/version.

The standard deviation of TESTVAL in specimen results file (spec_results) for this test/version.

Number of blind duplicate pairs used to calculate DUPAVGCV and DUPCORR.
