Test ID: CYSTC
Cystatin C with Estimated GFR, Serum
Method Description 
Describes how the test is performed and provides a method-specific reference
Serum sample from patient is mixed with Gentian cystatin C immunoparticles. Cystatin C from the sample and anti-cystatin C form the immunoparticles aggregate. The complex particles created absorb light, and by turbidimetry the absorption is related to cystatin C concentration via interpolation on an established standard calibration curve.(Package insert: Gentian Cystatin C Immunoassay on Cobas c501, Roche Diagnostics, Indianapolis, IN, June 2011)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
24 hours per day, 7 days per week
Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.
1 day
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result
2 days
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
7 days
Performing Laboratory Location Indicates the location of the laboratory that performs the test
