Light Blue.
The additive in these tubes is usually Na+ Citrate and there is a marking on the test tube to indicate the minimum fill. Blood must come at least up to the line or it will not be acceptable.
A clear or colorless test tube is typically used when performing a sodium test to accurately observe the color changes in the solution. If a colored test tube is used, it may interfere with the interpretation of the results.
You can use a clear test tube for a lactic acid test. This allows you to easily observe any color changes that may occur during the test, indicating the presence of lactic acid.
A light blue tube is typically used for testing sodium (Na) levels.
You would typically use a light blue-top tube containing sodium citrate for coagulation testing. This type of tube is used to prevent blood from clotting by binding calcium ions, which are essential for the coagulation process. It is important to fill the tube to the proper fill line to maintain the correct blood-to-anticoagulant ratio.
A light blue tube is typically used for a prothrombin time (PT) test.

The color tube commonly used for a lab serum Vitamin D test is a red or gold-colored tube, which may contain a gel separator. It is important to consult the lab or healthcare provider for specific instructions on which tube to use for the test.
The recommended color tube for rubella serology testing is a red or tiger-top tube with gel separator. This allows for serum separation, which is needed for the test.
A red-top tube is typically used in phlebotomy for an RPR (Rapid Plasma Reagin) test.
Red test tubes are typically used for the blood type Rh factor test.
For an albumin test, the recommended blood tube is a red-top tube or a serum separator tube (SST) as it does not contain any anticoagulant, which is necessary for the accurate measurement of albumin levels.
For an Aspartate Aminotransferase (AST) test, you would typically use a red-top tube, which does not contain any anticoagulant. This allows the blood to clot, separating the serum that is needed for the test.
