The colour tube commonly used for fasting blood tests is usually a plain red or gold-top tube. These tubes do not contain any additives that could affect the results of fasting blood tests.
The tube for fasting blood sugar tests is typically a lavender or purple-colored tube.
The blood specimen for a CRP test is usually collected in a lavender-top or clear tube with an EDTA anticoagulant. This tube is also sometimes referred to as a "purple-top" tube.
A light blue blood tube, also known as a sodium citrate tube, is typically used to test the International Normalized Ratio (INR). The sodium citrate acts as an anticoagulant, preventing blood from clotting so that accurate measurements can be obtained.
Gray top tube is typically used for fasting blood glucose (FBG) testing.
A red-top tube is typically used for a FSP (fasting serum panel) blood test. This tube does not contain any additives and is used to collect a sample of blood that will be spun down to separate the serum for testing.

Fasting is not required for an erythrocyte sedimentation rate (ESR) test, as it measures how quickly red blood cells settle in a tube over a specific amount of time. It is a non-specific test used to detect inflammation or an infection in the body. It is generally not affected by food intake.

A laboratory test where venous blood is clotted in a test tube is called a serum clotting test. Once the blood sample clots, it is centrifuged to separate the liquid portion (serum) from the clot, which can then be used for various diagnostic tests.
