A lavender or royal blue tube is typically used for collecting a TIBC (total iron-binding capacity) test.
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.
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).

The blood test code PLT represents the platelet blood test, otherwise known as platelet counts. TIBC stands for total iron binding capacity. The TIBC test assesses the amount of iron in the blood supply.
A lavender or royal blue tube is typically used for collecting a TIBC (total iron-binding capacity) test.
The TIBC test measures the amount of iron that the blood would carry if the transferrin were fully saturated. Since transferrin is produced by the liver, the TIBC can be used to monitor liver function and nutrition.
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.
When having a Total iron-binding capacity (TIBC) or transferrin, than it is necessary to avoid eating or drinking for 8 hours before the blood test. It is not necessary to fast when having a ferritin blood test.
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).

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 drawn blood has platelets of fat in it.
