Yes! We encourage the use of recovered plasma from the lithium heparin whole blood separator for other tests, such as the SNAP® T4 Test and SNAP® Total T4 Test.
All the questions
No. The recommended mixing method for the lithium heparin whole blood separator is to swirl the separator 5 times. If you choose to invert the separator and some blood becomes trapped in and/or around the cap, tap the separator gently on the counter to help release the blood from the cap. The sample volume that is trapped in the cap is not sufficient enough to cause issues with analysing the sample and obtaining results
Should the syringe needle be on or off when dispensing sample into the lithium heparin whole blood separator?
The needle should be off when dispensing sample into the separator.
The lithium heparin whole blood separator provides the benefit of plasma, which can be recovered after its use in the Catalyst Dx® Chemistry Analyser and used for your additional testing needs. If more blood is left in the patient syringe after dispensing the required volume of 0.6–0.8 cc into the separator, the remaining sample can be dispensed into any sample tube as long as the required fill volume is adequate.
