Store plasma aliquots upright at -80°C until shipment to NCRAD. Spin, aliquot, and freeze all plasma and buffy coat aliquots within 2 hours of collection.

Well-prepared plasma were those with plasma samples prepared according to Kong's laboratory manual, i.e., blood collected in EDTA tube, with 19-21 gage needle, with blood samples setting...

hematological and molecular testing. Plasma containing K2-EDTA may not be used to measure analytes such as potassium or divalent cations such as calcium. Blood plasma obtained from lavender-top tubes is commonly used for the following applications: Here we describe a step-by-step protocol for isolation and collection of plasma from tubes with ...

the order of draw is: blood gas syringe, EDTA tubes, sodium citrate tubes, all other anticoagulant tubes, serum/clot tubes • When performing paediatric collections, refer to CHART B for blood collection volume guidelines • Haemolysis warning. Never inject or force blood into the collection tube through a needle from a syringe

Ensure that the correct blood-to-additive ratio is met by checking the draw volume against the nominal fill mark on the tube or by holding tube up to this guide. Max. CLSI recommends 3.2% (0.109M) of buffered citrate for coagulation assays. If a winged blood collection set is used, the first tube drawn in the series will be under-filled.

2020年7月23日 · Protocol for preparing plasma for metabolomics studies / GWAS. Prepare 2ml eppendorf tubes to spin down whole blood. Ensure that blood is taken using tubes coated with EDTA ( heparin is not as good as it causes hemolysis ) Always keep blood at room temperature. Collect blood into the EDTA coated microvette tube.

Blood for hematologic testing must be collected into an anticoagulant, preferably EDTA (purple top tube). Blood smears should be made at the time of collection to minimize storage-associated changes, which invariably occur.
