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.
red top is plain tube, for clotted blood. purple top is edta tube, for blood cytology. grey top tube contain sodium flouride anti coagulant for blood sugar. green top tube contains heparin require for cd4, cd8, etc. sky blue top tubes contain sodium citrate 3.2% for bleeding disorder tests such as pti etc.
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.
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.
Rubidium
Clotted blood is normally obtained from a specimen of venous blood which has been allowed to clot by standing for 30 minutes. The resulting specimen is usually centrifuged to separate the clotted red blood cells from the serum.
You can send red tubes off to be tested. These tubes are used to collect blood and seamen.
The gel seperates the serum from the red blood cells
The Red/Gray color tubes have serum in the serum separating tubes.
long as they are not flashing red and blue lights and they are soft and tubes can not be seen.
The Red/Gray color tubes usually have serum in them.
Non additive red tube
you can have any color but red... and the tubes can't be visible you can have any color but red... and the tubes can't be visible

red lights, lasers, vacuum tubes, some TV tubes, etc.
You bleed from your vagina for anywhere from 4 to 9 days. The blood can be bright red and thin, dark red and "clotted", or a cross between red and brown which is called "old blood" (that happens at the beginning and end of your period).
