A green tube is typically used for collecting blood samples for tests that require heparin as an anticoagulant. It is commonly used for chemistry tests, including liver function tests, electrolyte panels, and certain hormone assays. The heparin in the green tube helps prevent clotting, allowing for the accurate analysis of plasma.
The test tube for BUN (Blood Urea Nitrogen) is typically light green or gray.
A hemoglobin A1c test is typically drawn in a lavender-top tube, which contains EDTA as an anticoagulant. This tube is specifically designed for collecting whole blood for tests that require EDTA for anti-coagulation.
The Pro Thrombin is also called a PT/INR and it is drawn in a light blue sodium citrate tube which is then spun down in a centrifuge to separate the plasma from the red cells and the plasma is used to run the test.
Venous blood clotted in a test tube is called a serum sample. Serum is the liquid component of the blood that remains after blood clots and is used for various diagnostic tests.
Oxygen
An activated partial thromboplastin time (APTT) test is drawn in a light blue tube. This tube contains sodium citrate as an anticoagulant to prevent blood from clotting during the test.
The CBC is drawn in a green tube. This is blood testing tubes.
An ammonia test is typically drawn in a green-top (heparin) tube as the anticoagulant.
Blood for a folate test is typically drawn in a lavender-top tube, which contains the anticoagulant EDTA. The lavender-top tube is used for collecting whole blood specimens for hematology testing.
Blood for a Basic Metabolic Panel (BMP) or Sequential Multiple Analysis (SMA) test is typically drawn into a green or red-topped tube. Green top tubes typically contain lithium heparin as an anticoagulant, while red top tubes do not contain any anticoagulant.
The most common test to be drawn in the lavender tube is a complete blood count (CBC), which includes measurements of red and white blood cells, hemoglobin, and platelets.
You just go to the lab and have it drawn. Just one tube of blood
A BUN (Blood Urea Nitrogen) test is typically drawn in a lavender or green-topped tube, which contains an anticoagulant called heparin. The choice of tube color may vary between healthcare facilities, so it's always best to confirm with the specific laboratory where the test will be done.
Blood for an albumin test is usually drawn in a red or gold-top tube, which contains a clot activator and serum separator gel. This allows the blood to clot and separate the serum, which is then used for the albumin test.
An arterial blood gas (ABG) sample is typically drawn in a heparinized syringe, not a tube. The heparin coating prevents the blood from clotting, allowing for accurate analysis of blood gases.
Creatinine is typically drawn in a lavender or green-top tube. The specific color may vary depending on the laboratory or facility. It is important to always follow the specific instructions provided by the facility where the blood test is being done.
The tube used for a serum ferritin test is typically a gold or tiger top tube.
