The most common anticoagulant used in vacuum tubes for blood collection is ethylenediaminetetraacetic acid (EDTA). It is effective in preserving blood samples by binding to calcium ions, preventing coagulation.
The most common tube color used for lupus testing is a red-top tube, which contains no anticoagulant. This allows for the blood to clot before testing. Additionally, a lavender-top tube containing EDTA anticoagulant may also be used for specific lupus tests.
A red tube with no anticoagulant is typically used for an AFP test.
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 typically requires a 1.9 ratio of anticoagulant to blood. This tube is often used for coagulation studies.
A red-top tube typically contains no anticoagulant. It is used for serum samples where blood is allowed to clot before being centrifuged to separate the serum.

vacuum tube
A light blue tube typically requires a 1.9 ratio of anticoagulant to blood. This tube is often used for coagulation studies.
A red-top tube typically contains no anticoagulant. It is used for serum samples where blood is allowed to clot before being centrifuged to separate the serum.
A red top tube containing no anticoagulant or a gel separator tube would be suitable for troponin testing.
A lavender/purple top tube (containing EDTA anticoagulant) is typically used for an iron test. This anticoagulant helps preserve the sample for accurate testing.
A royal blue or navy blue tube with no anticoagulant is typically used for lead testing.
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 color tube used for folate testing is typically a lavender or purple-top tube. These tubes contain the anticoagulant EDTA which is used to preserve the blood sample for testing.
A citrate tube used for blood drawing is usually light blue in color. This tube contains sodium citrate, which is an anticoagulant used for coagulation studies.
