The stoppers of vacutainer tubes are color-coded to indicate the type of additive or anticoagulant in the tube. This helps healthcare professionals select the appropriate tube for specific blood tests, ensuring accurate and reliable results.
A royal blue or navy blue tube with no anticoagulant is typically used for lead testing.
No, the liquid portion of a specimen collected in a tube containing EDTA is plasma. Serum is the liquid portion of a blood sample collected in a tube without anticoagulant. EDTA is an anticoagulant that prevents blood clotting by chelating calcium ions.
A purple or lavender-colored top tube with EDTA anticoagulant is typically used for collecting samples for a shingles test.
A PKU is a serum test, so it goes in a red top.
No, potassium oxalate is not added to the gray vacuum tube. The gray-top tube typically contains an anticoagulant such as potassium oxalate and sodium fluoride for glucose testing.
Gray tube
The color-topped evacuated tube typically used for the collection of blood for electrolyte testing is a green-top tube, which contains heparin as an anticoagulant. Heparin prevents clotting and ensures accurate testing of electrolyte levels in the blood.
If a blood sample is collected into an evacuated tube without an additive, the blood will clot naturally because there is no anticoagulant present to prevent clotting. This can lead to inaccurate test results as the clot formation may interfere with various analyses requiring liquid blood.
A light blue tube typically requires a 1.9 ratio of anticoagulant to blood. This tube is often used for coagulation studies.
to collect the blood specimenwith no anticoagulant inside the tube
A lavender or light blue tube is typically used for an amylase blood draw as it contains an anticoagulant (lavender tube) or no anticoagulant (light blue tube) needed for the test.
red topped tube
A red top tube containing no anticoagulant or a gel separator tube would be suitable for troponin testing.

Yes, lithium heparin
