Collecting A Sample; Performing A Test; Testing Warnings And Precautions - Siemens Healthineers Atellica VTLi User Manual

Do not touch the filter or hold the transparent area of the cartridge.

Collecting a sample

The following specimen types have been tested for use with the Atellica VTLi Immunoassay
analyzer:
‒ Venous whole blood or plasma.
‒ Capillary whole blood.
For sample tube specimen collection, follow the sample tube manufacturer's recommended
procedure. For capillary specimen collection, use a finger-stick method with a sample
transfer device, according to manufacturers recommendations.
When stored at room temperature (15-25⁰C), whole blood capillary samples should be
analyzed immediately and venous samples within 2 hours after sample collection.
If testing will be delayed more than 2 hours, plasma should be separated and analyzed
within 4 hours or it should be frozen.
Freeze samples in an ultra low temperature freezer at -55 °C or colder for up to 60 days.

Performing a test

Testing warnings and precautions

‒ Make sure the ambient temperature is within range as specified in Appendix A. If
necessary, dock the analyzer in the docking station to reach the correct temperature.
‒ You can cancel a test at any time. Depending on the workflow step, you can tap
return to the previous workflow step. You can also cancel a test by opening the analyzer
cover and removing the cartridge.
‒ Canceling a test in progress stops the current test and shows the Results screen from
where you can continue.
‒ The analyzer must remain in a horizontal position after applying the sample and during
the analysis processing. The analyzer displays a warning message when it detects a non-
horizontal position.
‒ If a sample is spilled, make sure to clean the analyzer, but only after the complete test
has finished.
‒ Do not drop, shake, or bump the analyzer after applying the sample.
‒ The sample type (venous, capillary, plasma) and the anticoagulant can affect the test
result. Make sure you follow the guidance in the workflow and adhere to the indicated
sample types .
‒ Do not use samples types other than the ones supported (venous, capillary, plasma).
‒ Make sure that the sample type you use matches the sample type you select on the
Select Sample Type screen during the testing process. Applying an unsupported
sample type may produce unexpected test results.
