The CoaguChek XS Plus System has quality control functions integrated into the meter and test strips. The system automatically runs its own 2-level quality control test as part of every blood test. The system performs:
- A check of the electronic components and functions every time the meter is turned on,
- A check of the expiration date and lot information on the test strip,
- A quality control function incorporated into the test strip.
- Automatic Internal Quality Control:
- The CoaguChek XS Plus meter performs an Automatic Quality Control test on the test strip before it displays the test result. “QC” appears in the display.
- A two-level, on-board quality control test is performed within the test chamber as part of every blood test.
- Following a successful outcome of the internal quality control test, a checkmark appears after “QC”.
- If the test strip fails the Internal Quality Control check, the test strip is unusable. Remove the test strip. Repeat the test using a new test strip and a new fingerstick from a different finger. If internal QC still fails, open a new box of test strip and retest. If test strip fails internal QC more than 3x, contact Point of Care Testing (POCT) Clinical Laboratory Scientist (CLS).
A Liquid Quality Control Testing must be performed – 1)with every new lot or new shipment of test Strips, 2)with every New or New Shipment lot of Quality Control, 3)when temperature is out of range, and 4)after troubleshooting or preventive maintenance is performed on the meter.
