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
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.
Many test tubes use EDTA as the anticoagulant - but there are other anticoagulants used as well. Be more specific if you wish a more specific answer.
EDTA
EDTA test tube (Lavender top) for CBC etc. Heparinized test tube (Green top) for CD4 and absolute lymphocyte count Sodium floride(Grey top) for sugar test.
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.
EDTA (ethylenediaminetetraacetic acid) is the additive put in the tube for Complete Blood Count tests to keep it from clotting.

Red top lavender top(k2 EDTA)
Many test tubes use EDTA as the anticoagulant - but there are other anticoagulants used as well. Be more specific if you wish a more specific answer.
EDTA
Lavender color tube containing the anticoagulant EDTA is ideal for CBC test.
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
There are many reasons why a person has to have a blood test done. Mega T Green Tea will show up in a blood test, and can alter the results.
