Blood for a folate test is typically drawn in a lavender-top tube, which contains the anticoagulant EDTA. The lavender-top tube is used for collecting whole blood specimens for hematology testing.
Blood for an albumin test is usually drawn in a red or gold-top tube, which contains a clot activator and serum separator gel. This allows the blood to clot and separate the serum, which is then used for the albumin test.
The tube used to draw blood for a comprehensive metabolic panel (CMP) test is typically color-coded as either red or tiger top (gold/yellow with a red ring).
An activated partial thromboplastin time (APTT) test is drawn in a light blue tube. This tube contains sodium citrate as an anticoagulant to prevent blood from clotting during the test.
The tube used for a serum ferritin test is typically a gold or tiger top tube.

Red test tubes are typically used for the blood type Rh factor test.

The tube used for a serum ferritin test is typically a gold or tiger top tube.
A light blue tube is typically used to collect blood for a coumadin test (PT/INR). This tube contains sodium citrate as an anticoagulant to prevent the blood from clotting during testing.
The drawn blood has platelets of fat in it.
A BUN (Blood Urea Nitrogen) test is typically drawn in a lavender or green-topped tube, which contains an anticoagulant called heparin. The choice of tube color may vary between healthcare facilities, so it's always best to confirm with the specific laboratory where the test will be done.
Red or lavendar
The color of the tube used to draw a blood urea nitrogen (BUN) test is typically purple or green. The specific color can vary depending on the laboratory or healthcare facility's protocol.
Creatinine is typically drawn in a lavender or green-top tube. The specific color may vary depending on the laboratory or facility. It is important to always follow the specific instructions provided by the facility where the blood test is being done.
