EDTA prevents clotting of blood by chelating calcium. If a certain blood test requires the blood to be unclotted, this is often used. It is the anticoagulant (chemical that prevents blood from clotting) of choice for most hematology tests.
In blood cell counts (including Red Blood Cells, White Blood Cells, and platelets) - EDTA is the preferred anticoagulant. If flow cytometry is needed on blood, it must be unclotted (collected in a tube that has no anticoagulatn)- CD4 counts are tested in this way.
If a test needs to identify something in specific cells, e.g. HIV DNA in lymphocytes, then the cells can't be part of a clot, so unclotted blood is used.
If plasma is required for a test, EDTA blood may be used (althought EDTA may not be appropriate for some plasma-based tests). Plasma is the liquid part of the blood without cells that has not clotted. Serum is the liquid part of the blood once the clot has formed. Some tests can use both, while other tests need one or the other.
EDTA whole blood refers to a blood sample that has been collected in a tube containing the anticoagulant ethylenediaminetetraacetic acid (EDTA). EDTA helps prevent blood clotting by binding to calcium ions, allowing the blood sample to be used for various laboratory tests such as complete blood count (CBC) and blood chemistry analysis.
The tube containing EDTA is typically the purple-top tube. EDTA is an anticoagulant used in blood collection tubes to prevent blood clotting by binding to calcium ions.
K2 EDTA (ethylenediaminetetraacetic acid) is a commonly used anticoagulant additive in blood collection tubes. It works by binding to calcium ions in the blood, preventing the blood from clotting. This allows for accurate testing of various blood components.
If a blood test shows that EDTA has clotted, it may indicate improper handling of the blood sample, which could lead to inaccurate test results. EDTA is an anticoagulant commonly used to prevent blood from clotting during sample collection. It is important to ensure proper techniques are used to collect and handle blood samples to avoid this issue.
The typical ratio of K2 EDTA to blood is around 1:9, meaning 1 part of K2 EDTA is used to collect 9 parts of blood. This anticoagulant helps preserve the blood sample by chelating calcium ions to prevent coagulation.

Purple Tops are used for full blood counts (CBC test). EDTA is the abbreviation for ethylenediaminetetraacetic acid (you can see why it's abbreviated). The EDTA in purple top tubes is actually usually the potassium salt of this. It's used to keep the blood from coagulating.

The stopper used for hemoglobin blood testing is lavender, and the additive is EDTA.
Yes, EDTA tubes contain plasma. When blood is collected in EDTA tubes, the ethylenediaminetetraacetic acid (EDTA) acts as an anticoagulant, preventing the blood from clotting. After centrifugation, the liquid portion above the formed cellular elements is plasma, which can be used for various laboratory tests.
The typical ratio of K2 EDTA to blood is around 1:9, meaning 1 part of K2 EDTA is used to collect 9 parts of blood. This anticoagulant helps preserve the blood sample by chelating calcium ions to prevent coagulation.
A full blood count EDTA is a common blood test that measures various components of your blood, including the number of red blood cells, white blood cells, and platelets. The EDTA additive is used to prevent the blood from clotting during the test, allowing for accurate measurements. This test can help diagnose conditions such as anemia, infection, and clotting disorders.
EDTA tube use for identify amount of blood. use for diagnosis disease relate with blood such as anemia, leukaemia, and any disease like thalasemia. beside that, this tube can use for identify microorganism in blood
Purple-top tubes, also known as EDTA tubes, are commonly used for hematology tests because the anticoagulant EDTA helps preserve blood cell morphology and inhibits clotting.
