The test tube color typically used for BNP (B-type natriuretic peptide) testing is lavender or purple, which contains EDTA as an anticoagulant. This type of tube is suitable for collecting whole blood or plasma samples. Always follow specific laboratory guidelines, as practices may vary.
red
A BNP (B-type natriuretic peptide) test is typically performed using a lavender or purple top tube, which contains EDTA as an anticoagulant. This color is commonly used for tests requiring plasma. However, laboratory practices may vary, so it's always best to confirm with the specific lab protocol.
B-type natriuretic peptide (BNP) is a hormone produced by the heart in response to heart failure. The vacutainer tube used to collect blood for a BNP test does not have a specific color requirement, as long as it contains an anticoagulant to prevent blood from clotting. The color of the vacutainer top may vary depending on the manufacturer or type of anticoagulant used.
HbA1C test tubes are typically light purple in color, signifying that the blood sample is for a chemistry test.
Gray tube
The correct color tube for a thrombin test is typically a light blue tube. This tube contains sodium citrate as an anticoagulant, which is needed for coagulation studies.
SST tube (yellow color)
The tube top color for an acid phosphatase blood test is lavender.
blue tube
A clear or transparent test tube is typically used for a lipid test to easily observe any color changes or reactions that occur during the test.
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.
A red tube with no anticoagulant is typically used for an AFP test.
