Not all of them are. Red top plastic tubes contain a coagulant and are used for serology. Red top glass tubes contain no additives and are used for various tests that require blood that has not been adulterated in any way.
sst You would use the plan red top tube or serum obtaining tubes. Those could be red or red/gold an so on.
The tubes used for fasting glucose is the SST tubes. The tubes are clear in color. The stoppers for the tubes are gold and red gray in color. The tubes contain a gel inside for separating the blood.
Depends who you buy your red top tubes from, but mostly no. A serum seperator tube (SST) is usually yellow or gold top, it has a lump of clear gel in the bottom. When spun this gel ends up between the serum and red blood cellsmaking it easier to seperate the serum. A red top is generally a tube with nothing at all in it. So when spun you end up with serum and clotted red cells but nothing seperating them. Most other colour tubes contain an anti coagulant preventing the blood from clotting so when spun you end up with plasma and red cells. The important thing for most tests is the difference between serum and plasma, so a red top and an SST can generally be used for the same tests although SST is often prefered as its easier to work with.

For venous blood specimens, if it is test tubes used in blood collection that you are referring to, the gel is a serum separator. When the sample is centrifuged, the red cells will spin to the bottom, plasma to the top, gel separating the blood components.
