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.
KC stands for "potassium citrate," which is a compound used as an anticoagulant in blood tests to prevent the blood sample from clotting.
B-type natriuretic peptide (BNP) is a hormone produced by the heart in response to heart failure. The vacutainer tube used to collect blood for a BNP test does not have a specific color requirement, as long as it contains an anticoagulant to prevent blood from clotting. The color of the vacutainer top may vary depending on the manufacturer or type of anticoagulant used.
The tube typically used for HgbA1C blood test is purple or lavender. These tubes contain an EDTA anticoagulant which helps preserve the blood sample for accurate testing.
The tube color typically used for a prothrombin time (PT) blood test is a light blue-top tube containing sodium citrate as an anticoagulant.
A lavender or purple-top tube is commonly used for a glycohemoglobin test. This tube contains the anticoagulant EDTA, which helps preserve the blood sample.

prothrombin time
If they have a history of having blood clots is a main reason. Possibly stroke, but I'm not positive. It just reduces the clotting factors in your blood.

A lavender or purple-top tube is commonly used for a glycohemoglobin test. This tube contains the anticoagulant EDTA, which helps preserve the blood sample.
The Direct Combs RH test typically requires a lavender/purple top tube, which contains EDTA anticoagulant to prevent blood coagulation. This type of tube is used for collecting blood samples for hematology tests, including the Direct Coombs test.
The light blue tube is typically used for PTT (Partial Thromboplastin Time) blood test in phlebotomy. It contains sodium citrate as an anticoagulant to prevent blood clotting for accurate testing of blood coagulation.
Coumadin is used to thin the blood.
A lavender or light blue tube is typically used for an amylase blood draw as it contains an anticoagulant (lavender tube) or no anticoagulant (light blue tube) needed for the test.
A light blue tube is typically used for a partial thromboplastin time (PTT) test. This tube contains sodium citrate as an anticoagulant to prevent blood clotting during the test.
