Why is EDTA tube used for CBC?

Why is EDTA tube used for CBC?

Anticoagulants are used to prevent clot formation both in vitro and in vivo. Historically, EDTA has been recommended as the anticoagulant of choice for hematological testing because it allows the best preservation of cellular components and morphology of blood cells.

What is EDTA tubes used for?

Pink-top tube (EDTA) This tube contains EDTA as an anticoagulant. These tubes are preferred for blood bank tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.

Which test is done in EDTA tube?

General Information. In general, hematology testing is performed on EDTA- (purple top tube) anticoagulated blood.

What is EDTA tube?

EDTA stands for Ethylenediaminetetraacetic acid. EDTA functions by binding calcium in the blood and keeping the blood from clotting. BD Vacutainer Plus Blood Collection Tubes contain K2EDTA, which is spray-dried to the walls of the tube.

What is EDTA whole blood?

Ethylenediaminetetraacetic Acid, or EDTA is an aminopolycarboxylic acid used as an anticoagulant in evacuated tubes. It inhibits the clotting process by removing calcium from the blood. High quality smears can be obtained from an EDTA blood sample within 2-3 hours.

What is EDTA blood tube?

What blood test is 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 is EDTA in blood test?

What color tube is EDTA?

Lavender
Lavender-top tube: Contains K2 EDTA. Use: EDTA whole blood or plasma.

How does EDTA prevent blood from clotting?

EDTA, by binding/chelating ionic calcium of blood, prevents the blood from clotting, since ionic calcium is one of the blood clotting factors required for blood coagulation.

What type of test is in an EDTA tube?

Routine hematology tests that use EDTA tubes include hemoglobin, hematocrit, white blood cell, red blood cell, and platelet count, reticulocyte count, eosinophil count, body fluid counts, sickle cell test, and erythrocyte sedimentation rate .

What can be EDTA be used for?

EDTA is used to lower blood levels of calcium when they have become dangerously high. EDTA is also used to control heart rhythm disturbances caused by a heart medication called digitalis (digoxin, Lanoxin).

How does EDTA tubes work?

Ethylenediaminetetraacetic acid (EDTA) strongly and irreversibly chelates (binds) calcium ions, preventing blood from clotting. Citrate is in liquid form in the tube and is used for coagulation tests, as well as in blood transfusion bags. It binds the calcium, but not as strongly as EDTA.
