What is a clot activator tube?
VACUETTE® CAT serum separator clot activator tubes contain a separating gel that migrates up to the interface between serum and clot during centrifugation, where it forms a stable barrier and separates the serum from the fibrin and cells.
How do you use a clot activator tube?
Time for complete clot reaction: 10-25 min. Centrifugation speed: 3500-4000 R/M….Precaution
- Recommended storage temperature: 4-25°C.
- Invert the tube 8-10 times immediately after drawing the blood.
- Erythrocyte, Leucocytes and Thrombocytes should complete in 24 hrs after drawing blood in EDTA tube.
What is the purpose of thrombin additive in a blood collection tube?
In the final step of clot formation, thrombin is required to convert fibrinogen to fibrin. To prevent the clotting process, heparin increases the activity of antithrombin III, which inhibits the activity of thrombin and thus prevents fibrin formation.
What does clot activator tube contains?
This tube contains potassium oxalate as an anticoagulant and sodium fluoride as a preservative – used to preserve glucose in whole blood and for some special chemistry tests.
Which type of blood collection tube contains a clot activator and a gel?
serum separator Serum separator tube
Clot activator and gel for serum separator Serum separator tube (SST) contains a gel at the bottom to separate blood cells from serum on centrifugation. Chemistry, Immunology and Serology.
What most likely caused the clot in this specimen?
Clotted sample Clotting can occur if your blood is not mixed thoroughly after collection (the tube needs to be inverted 5times) or if you have taken a long time to collect your sample and the blood has clotted before mixing takes place.
What is WB EDTA?
An EDTA test is used to assess the function of your kidneys through a series of blood tests. EDTA refers to the name of the substance that you will receive by injection. EDTA contains a small amount of radioactive material. This allows it to act as a tracer which will show the kidney function.
What happens if a sodium citrate tube is underfilled?
Underfilled sodium citrate tube. Citrate distributes only in plasma and if a tube is underfilled, the reduced plasma volume will contain more citrate anticoagulant, leading to increased calcium chelation (see citrate tubes A–E).
Why is red top tube rejected?
Hemolysis Lysis of red blood cells during collection or handling of blood specimens may cause hemoglobulin or other components to escape from the cells into the serum or plasma. Grossly or moderately hemolyzed specimens may be rejected.
What is the use of clot activator serum tube?
Clot Activator Serum Tube is used for blood collection and conventional serum experiment, such as clinical biochemistry test, immunity test, radioimmunoassay test, PCR and so on.
What is the difference between CLOT activator and additive?
Additive: None or contains silica particles which act as clot activators. What additive does: Clot activator promotes blood clotting with glass or silica particles.
What are the additives used in blood collection tubes?
Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant). The list below lists the most commonly used blood collection tubes, their additives and uses in laboratory: 1. Red.
What is an evacuated tube system for blood collection?
The evacuated tube system for blood collection in use for various laboratory tests consists of tubes of various sizes, with color coded tops indicating tube contents. Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant).
