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.

What is EDTA whole blood?
EDTA whole blood is whole blood that has been drawn into a tube with EDTA in it. The EDTA is added to transport samples and prevents the blood from clotting.
What is K2 EDTA?
K2 EDTA are blood collection tubes that are used throughout the medical field. These tubes are designed to inhibit the coagulation of blood.
Full blood count EDTA what does that means?
Full blood count is a measure of the levels of your Heamoglobin, white/red bloodcells and more. EDTA is an anticoagulant used in the bloodtube to prevent the bloodsample to clot.
What is the ratio of K2 EDTA per ml of blood?
1,8mg
What is the function of EDTA tube in blood?
act as anticoagulant to prevent clotting

What is purple top blood test what does EDTA mean?
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.
What binds with edta to prevent the blood from clotting?
calcium bind with the EDTA to prevent the blood from clotting
What color stopper is used for hemoglobin blood testing?
The stopper used for hemoglobin blood testing is lavender, and the additive is EDTA.
Full blood count EDTA what does that means?
Full blood count is a measure of the levels of your Heamoglobin, white/red bloodcells and more. EDTA is an anticoagulant used in the bloodtube to prevent the bloodsample to clot.
What is an EDTA blood test?
EDTA (ethylenediaminetetraacetic acid) is the additive put in the tube for Complete Blood Count tests to keep it from clotting.
What is the optimal time for measuring the mean platelet volume on an automated blood count if an EDTA blood specimen is used?
1 to 4 hours
Why edta blood not suitable for culture?
EDTA kills bacteria or renders it un-viable for growth. EDTA chelates metals that some bacteria need for growth.
What kind of tube is used for CBC?
It all depends on what system your using. If by tube you are referring to vaccutainers (blood sample containers) then you have to check. I know that purple top (EDTA) is for the ABC CBC machine as well as a manual blood smear since you need whole blood and EDTA minimizes any distortions.
What concentration of EDTA should be used for anticoagulation?
Ok, it's 1.5 mg per mL of Blood, you can reach this concentration by disolving 0.6 mg of EDTA in 10 mL of still water, then you add 100 microLitters (0.1mL) of this 6% EDTA into a glass tube. The next thing you've to do is to dry the test tube so that you'll only have 6 mg of EDTA, enough to anticoagulate exactly 4 mL of fresh complete blood. The final concentration of EDTA in the blood should be into the range of 1.25 to 1.75 mg per mL. I found this in Dacie's Haematology. karlosgb@live.com.mx
What is the ratio of K2 EDTA per ml of blood?
