The term "blue tube" often refers to a type of medical or laboratory tube used for collecting blood samples. Typically, these tubes contain additives that prevent clotting, making them suitable for various tests, including biochemical analyses. Depending on the specific use, blue tubes may also be used in other contexts, such as for air or fluid transfer in certain technical applications. Always consult specific guidelines or protocols for accurate usage.

A blue tube is typically used for coagulation tests, most commonly for prothrombin time (PT) and activated partial thromboplastin time (aPTT). These tests assess the blood's ability to clot and are crucial for monitoring patients on anticoagulant therapy or for diagnosing bleeding disorders. The blue tube usually contains sodium citrate as an anticoagulant, which helps preserve the sample for accurate testing.
Yes, when using a winged infusion set (wing tip), it is recommended to use a clearing tube before drawing a light blue (sodium citrate) tube, SST (serum separator tube), and lavender (EDTA) tube. The clearing tube, typically a non-additive tube, helps to prevent contamination from the winged set and ensures accurate test results. This practice is essential for maintaining the integrity of the samples for coagulation and hematology tests.

Typically, a lavender or blue-top tube is used to collect samples for CRP (C-reactive protein) testing.
The color tube you use when drawing blood for a lab test depends on the type of test you are running. For a Na blood test you would use a red tiger strip tube.
