Venepunture Final
Venepuncture Tubes
| Question | Answer |
|---|---|
| Yellow top tube | *Additive-Sodium polyanetholsulfonate (SPS)*Additive function -prevents blood from clotting and stabilizes bacterial growth*Lab use- for blood or body fluid cultures |
| Red | *additive- NONE *Lab use - serum testing, blood bank, serology |
| Red-gray (marbled) | *additive -none BUT contains silica particles to enhance clot formation*labe use- coagulation testing |
| Light blue | *Additive- soduim citrate*additive funtion- removes calcuim to prevent blood from clotting*Lab use for Chemistry testing |
| Green | *Additive- Heparin (sodium/lithium/ammonium)*Aadditive funtion- inhibits thrombin formation to prevent clotting*Lab use-Chemistry testing |
| Green-gray (marbled)/ light green | Additive- lithium heparin & gelAdditive function- for plasma separation*Lab use- used for plasma determination in chemistry studies |
| Yellow gray (marbled) Light green | *Additive is thrombin*Lab use & additive funtion used for stat serum demonstrations in chemistry studies |
| Lavender | *Additive- -Ethlenediaminete acid (EDTA)Additive function- removes calcuim to prevent blood from clotting*Lab use- used in hemetology testing |
| Gray | Additive- Potasuim oxolate and sodium fluorideAdditive function- removes calcuim to prevent blood from clotting; fluoride inhibits glycolysisLab use for chemistry testing , epecially glucose & alcohol levels |
| Royal blue | Additive _contians soduim heparin (also soduim EDTA)Additive function- inhibits thrombin formation to prevent clottingLab Use-used in Chemistry trace elements |
