The tube used to draw blood for a comprehensive metabolic panel (CMP) test is typically color-coded as either red or tiger top (gold/yellow with a red ring).
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 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 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 tube used for a serum ferritin test is typically a gold or tiger top tube.
A light blue tube is typically used to collect blood for a coumadin test (PT/INR). This tube contains sodium citrate as an anticoagulant to prevent the blood from clotting during testing.

The blood for IGF-1 is typically drawn in a plain red-top tube.
Red or lavendar
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.
The tube used to test for glucose tolerance is typically a gray-top tube. This tube contains a preservative that helps prevent changes in glucose levels after the blood is drawn, ensuring accurate test results.
The tube for an anti-DNA test is typically purple on the top and lavender on the bottom, known as a lavender-top tube. This tube contains EDTA, an anticoagulant that helps preserve the blood sample for testing.
The color of the tube used to draw a blood urea nitrogen (BUN) test is typically purple or green. The specific color can vary depending on the laboratory or healthcare facility's protocol.
The tube used for drawing blood for a prostate-specific antigen (PSA) test is typically a red or gold-top tube. These tubes contain a gel separator that helps separate serum from blood cells during centrifugation.
