Is sodium chromate the same as edta?
No, sodium chromate and EDTA (ethylenediaminetetraacetic acid) are not the same. Sodium chromate is a chemical compound containing sodium and chromium, while EDTA is a chelating agent often used in analytical chemistry and as a food additive or in medical applications.
DOES EDTA TUBES CONTAIN PLASMA?
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.
Why edta blood not suitable for culture?
EDTA (ethylene diamine tetraacetic acid) is a strong chelating agent that binds to calcium and magnesium ions present in blood, which are essential for bacterial growth in culture media. This can inhibit the growth of bacteria and other microorganisms, making EDTA blood unsuitable for culture. Additionally, the presence of EDTA can interfere with certain biochemical tests conducted during bacterial culture.

Why is EDTA the preferred anticoagulant?
EDTA is the preferred anticoagulant for blood samples because it chelates divalent cations like calcium and magnesium, preventing blood from clotting by inhibiting the coagulation cascade. It helps preserve the integrity of blood samples for laboratory analysis by preventing clot formation. Additionally, EDTA does not interfere with most laboratory tests, making it a versatile anticoagulant choice.

What is EDTA whole blood?
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.
What is green top blood test what does EDTA mean?
A green top blood test typically refers to a blood collection tube containing the anticoagulant EDTA. EDTA stands for ethylenediaminetetraacetic acid, which helps prevent the blood from clotting by binding to calcium ions. This allows for accurate testing of various blood components such as cell counts and certain chemistry tests.
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 are the different types of tubes used for blood collection and how do they differ in terms of their purpose and composition?
There are several types of tubes used for blood collection, including EDTA tubes, serum tubes, heparin tubes, and plasma tubes. These tubes differ in their purpose and composition. EDTA tubes are used for collecting blood for complete blood counts and other hematological tests, containing an anticoagulant called EDTA. Serum tubes are used for tests that require serum, such as chemistry tests, and do not contain any anticoagulant. Heparin tubes contain the anticoagulant heparin and are used for tests that require plasma, such as coagulation studies. Plasma tubes also contain an anticoagulant and are used for tests that require plasma, such as glucose testing.
Is sodium chromate the same as edta?
No, sodium chromate and EDTA (ethylenediaminetetraacetic acid) are not the same. Sodium chromate is a chemical compound containing sodium and chromium, while EDTA is a chelating agent often used in analytical chemistry and as a food additive or in medical applications.
What is the equivalent weight of EDTA?
The equivalent weight of EDTA (ethylenediaminetetraacetic acid) is 292 g/mol. It is a commonly used complexing agent in analytical chemistry for chelating metal ions.
DOES EDTA TUBES CONTAIN PLASMA?
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.
How does EDTA effect potassium level?
EDTA can chelate or bind to potassium ions in the blood, forming a complex that reduces the amount of free potassium available for measurement in laboratory tests. This can lead to falsely low potassium levels in blood tests. It is important for healthcare providers to be aware of this interference when interpreting potassium levels in patients who are receiving EDTA therapy.
What is EDTA blood used for?
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.
Why edta blood not suitable for culture?
EDTA (ethylene diamine tetraacetic acid) is a strong chelating agent that binds to calcium and magnesium ions present in blood, which are essential for bacterial growth in culture media. This can inhibit the growth of bacteria and other microorganisms, making EDTA blood unsuitable for culture. Additionally, the presence of EDTA can interfere with certain biochemical tests conducted during bacterial culture.
What type of specimen is required for most blood tests?
For most of the blood tests fasting blood specimen is required
