sodium heparin
the red top tube has no additives, the gold/speckled top tube has a gel in it but the explain red top tube has nothing nothing nothing in it.
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.
An ethanol level is typically drawn in a gray-top tube containing potassium oxalate and sodium fluoride as preservatives.
The haptoglobin test is typically collected in a red-top tube, which does not contain any additives. Alternatively, it can also be collected in a serum separator tube (SST).
A red-top tube is typically used for rubella testing, as it contains no additives and allows for serum separation after centrifugation.

Gray tube
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.
Because some tubes have additives (ie Heparin and Potassium) that can contaminate the next blood tube and skew the results. For instance, if you put blood into the tube with Heparin and then the tube used for coagulation studies the Heparin has the potential to thin the blood in that tube giving you a falsely high result
Clotting
An ethanol level is typically drawn in a gray-top tube containing potassium oxalate and sodium fluoride as preservatives.
The additive in red-gray or red-black speckled collection tubes is typically a clot activator and gel separator. These additives help to separate the blood sample from the serum after centrifugation, allowing for easier testing of the serum without interference from clots or cells.
The haptoglobin test is typically collected in a red-top tube, which does not contain any additives. Alternatively, it can also be collected in a serum separator tube (SST).
