What is a lithium heparin tube used for?

They are used for plasma determinations in chemistry. ▲ BD CLINICAL ADVANTAGE: BD Vacutainer® PST™ Lithium Heparin Tubes eliminate the need to wait for a clot to form, making it an ideal tube for STAT procedures, as well as for patients receiving anticoagulant therapy.

What is a sodium heparin tube used for?

Dark green-top tube (sodium heparin) This tube contains sodium heparin used for the collection of heparinized plasma or whole blood for special tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.

What is the difference between lithium heparin and EDTA?

In conclusion, density gradient centrifugation of K3EDTA blood resulted in higher purity of bovine granulocytes compared to lithium heparin blood. In contrast to water lysis, NaCl lysis method is recommended to avoid pre-activation of cells which may occur during hypotonic water lysis.

What color tube is lithium heparin?

Green-top tube: Contains sodium heparin or lithium heparin. Use: Heparinized whole blood or plasma.

What is the difference between sodium and lithium heparin?

Sodium heparin is the naturally occurring salt of heparin used medicinally and in the laboratory. Lithium heparin, which is used exclusively in the laboratory as an in vitro anticoagulant, is prepared from sodium heparin by cation-exchange chromatography.

What is the difference between SST and PST tubes?

SST/tiger tops contain a clot activator and gel separator, used to separate serum from blood products. Along with the gel separator, PST collection tubes also contain an anticoagulant additive, used to separate plasma from blood.

What is lithium heparin?

Aqueous lithium heparin is a superior anticoagulant to solid heparin for blood collection from the retro-orbital sinus of rats. Lab Anim.

Why is EDTA used instead of heparin?

EDTA Is a Better Anticoagulant than Heparin or Citrate for Delayed Blood Processing for Plasma DNA Analysis. Author for correspondence.

Is sodium heparin the same as lithium heparin?

Is lithium heparin the same as heparin?

We can surmise from the terms ”sodium heparin” and ”lithium heparin” that they are slightly different versions of the drug heparin. More technically, they are salts of heparin. Pharmacologically speaking, a salt is an ionizable drug that is added to a counter-ion in order to create a neutral substance.

What is the difference between a red serum tube and an SST tube?

Red Top: Does not contain an anticoagulant. This tube is used for collecting serum or clotted whole blood specimens. This tube should be used for all drug levels. Serum Separator Tube (SST) (Tiger Top): Does not contain an anticoagulant but contains a clot activator and serum separator gel.
