What blood tube is used for chemistry?
Light Green Top Tube (PST): This tube is used for serum HCGs and other routine chemistry tests. The tube contains lithium heparin as an anticoagulant. Black Top Tube (Vac-Tec): This tube is used for sed rates (ESR). The tube contains sodium citrate as the anticoagulant.
Which tubes to draw for labs?
Standard order of draw: BLOOD CULTURES, royal blue, red, light blue, SST (Gold), green, tan, yellow, pink, pearl, lavender. If a coag tube (light blue) is the only tube or the first tube to be drawn, a 5 mL discard tube must be drawn first.
What tests are red top tubes used for?
Red Top: Does not contain an anticoagulant. This tube is used for collecting serum or clotted whole blood specimens. This tube should be used for all drug levels.
What is the purple top tube used for?
The purple top tube provides blood for infectious disease tests and ascertaining important data such as ABO/Rh (blood type), as well as whether the blood is positive or negative for cytomegalovirus (CMV), HIV, hepatitis, and West Nile virus, to name a few.
What is a yellow blood test for?
The yellow blood bottle can be used to test for a wide variety of bacterial, viral, fungal and parasitic infections including HIV and viral hepatitis.
What is a brown blood test for?
Brown-coloured serum is normally caused by serious conditions such as massive intravascular haemolysis or methemoglobinaemia. In intravascular haemolysis, haemoglobin from the erythrocytes will be released and bind to haptoglobin in the circulation.
What color tube is EDTA?
EDTA whole blood = Lavender (purple) top tube Label this tube with owner name, animal ID, and as EDTA whole blood.
What are blue top tubes used for?
Blue Top – Tube contains Sodium Citrate. Most often used for coagulation studies. Must be drawn prior to collection of serum tubes to prevent contamination with clot activator and interference with coagulation cascade.
What tests are done using the light blue tube?
There is a severe nationwide shortage of light blue sodium citrate blood collection tubes used for coagulation laboratory tests such as prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, and D-dimer.
What test can a gray top tube be used for?
Gray top tube with potassium oxalate/sodium fluoride: used for lactic acid testing and other plasma or whole blood determinations.
What are different colored blood tubes used for?
Red: Contain NO anticoagulants, used for serum testing. Serum is fluid that is left behind after the cells are removed due to clotting. Gold: Contains a clot activator and special gel to separate serum from the cells. Purple: Contains a clot blocker and are used for complete blood count(CBC).
What is an EDTA tube used for?
Routine hematology tests require a blood collection tube containing EDTA, a chelating anticoagulant. EDTA preserves the morphology of the cellular elements of blood, making it a satisfactory anticoagulant for hematologic studies.
What are the 5 blood tests?
- Complete blood count (CBC).
- Basic metabolic panel.
- Blood enzyme tests.
- Blood tests to check for heart disease.
- Blood clotting tests, also known as a coagulation panel.
What are the three main blood tests?
A blood test is typically composed of three main tests: a complete blood count, a metabolic panel and a lipid panel.
Why do they take 3 vials of blood?
Out of the 5 liters of blood in your body, even 3-5 full vials are a safe quantity and unsubstantial, so don’t worry! This ensures that enough samples are available for back-up in case some samples are compromised. It also allows for any confirmatory tests that may be needed after the initial tests.
What is the green blood bottle for?
The light green tube can be used for plasma, while the dark green tube can be used for plasma or whole blood. The light green tube may be used as an alternative to the ‘gold top’ to perform routine biochemistry tests and therapeutic drug monitoring.
What color is serum?
THE yellow colour of human serum is generally assumed.to be caused mainly by bilirubin.
What tubes are used for CBC and CMP?
Container. Gel-barrier tube is preferred (send entire tube). Red-top tube or green-top (lithium heparin) tube is acceptable.
What color tube is used for potassium test?
Container. Red-top tube, gel-barrier tube, or green-top (lithium heparin) tube.
How do I remember my phlebotomy tubes?
The order of draw is an order of tubes phlebotomist should follow to prevent testing complications and cross-contamination of additives.

What is EDTA in chemistry?
A chemical that binds certain metal ions, such as calcium, magnesium, lead, and iron. It is used in medicine to prevent blood samples from clotting and to remove calcium and lead from the body. It is also used to keep bacteria from forming a biofilm (thin layer stuck to a surface). It is a type of chelating agent.
Which test is done in EDTA tube?
In general, hematology testing is performed on EDTA- (purple top tube) anticoagulated blood.
What tube is ammonia level?
Lavender-top (EDTA) tube; EDTA is the only acceptable anticoagulant.
What is a full blood test called?
Full blood count (FBC) This is a test to check the types and numbers of cells in your blood, including red blood cells, white blood cells and platelets. This can help give an indication of your general health, as well as provide important clues about certain health problems you may have.
