Quality control procedure

Starrsed Control is provided in ready-to-use sample tubes and is used in the same manner as patient samples. Starrsed Control is to be used for the Westergren method with dilution only as prescribed by the "ICSH review of the measurement of the ESR" (2011) and the "CLSI Procedures for the ESR Test; Approved standard; H02-A5" (2011).

1. When using LAB ID: Link the Lab ID with Starrsed Control Sample ID, see chapter Linked QC IDs. Attach the lab ID label on the tube on top of the original Starrsed Control label
2. Rub the Starrsed Control tube between hands until packed cells have been completely re-suspended. (See also video instruction https://portal.rrmechatronics.com/whatiseqas/)
3. Place tube for at least 15 minutes on a roller mixer or rotator mixer for thoroughly
   mixing. Avoid foaming. DO NOT VORTEX.
   NOTE: To ensure consistent and reproducible results, the Control material must be thoroughly mixed and handled in the same manner each time.
4. Place Starrsed Control tube immediately after mixing into the analyzer.
5. Start the Sample mode. The Starrsed Control sample is processed in the same manner as a patient sample. Depending on the settings in "QC settings", a request and/or result is sent to the LIMS.
6. Restore tube after each use (at 18°-30°C).

For detailed information see the Starrsed Control Package Insert.

The contents of one tube is sufficient for three Control samples. Do not mix residual material with material from other tubes. Do not re-use empty tubes.
