Which tube is used in coagulation testing and why?
The specimen of choice for coagulation testing is plasma. Venous blood is drawn into a 3.2% buffered sodium citrate tube (blue top tube), yielding a whole blood sample with a 9:1 blood to anticoagulant ratio. Inadequate filling of the collection tube will decrease this ratio, and may affect test results.
Can an EDTA tube be used for coagulation studies?
This makes EDTA suitable to be used as an anticoagulant. However, due to its chelating properties to continue with the calcium ions binding even if more calcium is added, like in coagulation tests, EDTA is not suitable as anticoagulant in samples assigned for coagulation testing (8).

What is coagulation tube?
Vitrex Coagulation Tubes are used to collect venous blood for coagulation tests. Coagulation Tubes have a buffered sodium citrate solution of 0.109 mol/l (3.2%) or 0.129 mol/l (3.8%). Double Tube technology provides an excellent condition for the test of PT and APTT values.
What is a blue top tube used for?
Blue top tube with 3.2% sodium citrate: used for coagulation testing and other plasma or whole blood determinations.
Which anticoagulant is used for coagulation studies?
For most coagulation tests, trisodium citrate (1 : 9 ratio of citrate to blood) is the anticoagulant of choice.
What is an EDTA tube used for?
EDTA acts as an anticoagulant, binding the calcium ions and interrupting the clotting of the blood sample. EDTA is used for most hematology procedures, assessing complete blood count, preparing EDTA plasma, whole blood collection and bone marrow specimens.
What is EDTA coagulation?
Ethylenediaminetetraacetic acid (EDTA) is a well-known anticoagulant since early 1950s and it has certain advantages over other anticoagulants [2]. It inhibits clotting by removing or chelating calcium from the blood.
What is the difference between aPTT and PTT?
Description. Partial thromboplastin time (PTT) and activated partial thromboplastin time (aPTT) are used to test for the same functions; however, in aPTT, an activator is added that speeds up the clotting time and results in a narrower reference range.
Are PT and PTT the same?
Partial thromboplastin time (PTT) is a blood test that looks at how long it takes for blood to clot. It can help tell if you have a bleeding problem or if your blood does not clot properly. A related blood test is prothrombin time (PT) .
What color tube is used for INR?
A light-blue top tube (containing 3.2% sodium citrate) that will be used for coagulation testing must be filled to completion.
What is the difference between sodium citrate and EDTA?
EDTA anticoagulation is used for blood counts; sodium citrate is used for coagulation testing and for the erythrocyte sedimentation rate.
Why is heparin not used for coagulation studies?
Heparin is not recommended as an anticoagulant because leukocytes and thrombocytes clump, invalidating WBC counts and differential cell counts.
What is heparin tube used for?
Sodium Heparin or Lithium Heparin Tubes are used to produce plasma for biochemical testing. The Heparin Tubes are also available with Gel separator. The range of application is: clinical chemistry and trace mineral testing.
Why is sodium citrate used for coagulation studies?
Background :Sodium citrate has been used as a coagulation test because factor V and VIII are more stable in a citrated specimen. Ethylenediaminetetraacetic acid (EDTA) has been used for the hematologic test because blood cells are preserved better in the EDTA specimen.

Why are color indicators important for phlebotomy?
These color indicators help the phlebotomist to easily select the tubes in which the blood should be drawn as per the tests that have to be performed. The additives present in the vacutainer tubes plays the most important role as every additive has a unique function and these are selected as per the tests to be performed.
Why is the exact volume that should be drawn in a specific vacutainer tube mentioned on the label of every?
Moreover, the exact volume that should be drawn in a specific vacutainer tube is mentioned on the label of every tube which is to minimizes the errors that may occur if more or less amount of blood is taken in the tube because every tube contains an anticoagulant or an additive or Clot activator in some and the ratio of the blood to the Additive must be maintained in order to get the accurate values of the tests.
What happens when you insert a vacutainer tube into a tube?
When a Vacutainer tube is inserted into the holder, its rubber cap is punctured by the inner needle and the vacuum in the tube pulls blood through the needle into the tube.
How does a vacutainer tube work?
Vacutainer tubes work on the pressure difference that is created between the blood vessel and the vacuum in the tubes which forces the blood through the needle into the tube. Vacutainer needle is double-ended, with one side being encased in a thin rubber coating for safety and the other side for the insertion into the vein.
Who invented vacutainer tubes?
Vacutainer tubes were invented by Joe Kleiner and BD (Becton, Dickinson & Co.) in 1949. These tubes are the registered trademark of Becton, Dickinson & Co. and today vacutainer tubes are manufactured and sold by them.
What is a vacutainer tube?
A Vacutainer blood collection tube is a sterile glass or plastic tube with a closure that is evacuated to create a vacuum inside the tube facilitating the draw of a predetermined volume of liquid. Most commonly used to draw the blood samples directly from the vein. These tubes can also be used sometimes for the collection of urine samples.
