The specimen is usually the glass particle in the serum separator tubes.
Inhibit glycolysis
The Red/Gray color tubes have serum in the serum separating tubes.
these tubes are used in those tests where serum used. when blood clot, serum is obtained after the centrifugation.
serum tubes
yes
The Red/Gray color tubes usually have serum in them.
In test tubes.
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.
