Blood Collection Tube Color Code
When you visit a healthcare provider for blood tests, you may notice that they use different colored tubes to collect your blood samples. These color-coded tubes serve a specific purpose and help healthcare professionals easily identify the type of test that will be conducted on the blood sample. In this article, we will discuss the blood collection tube color code system and what each color tube represents.
