crust
The term for a collection of dried serum and cellular debris is called a crust.
Serum is generally free from blood cellular components but when collecting serum sometimes few cells will be pipetted with the serum & that is the only source of DNA in the serum.
A dried collection of blood, serum, or pus. Also called a scab, a crust is often part of the normal healing process of many infectious lesions.
Dried human plasma and human serum is prepared by freeze-drying or by other methods that will avoid denaturation of the proteins. This will yield a product readily soluble in a quantity of water equal to the volume of liquid plasma and human serum.
A serum separator tube (SST) typically yields serum after centrifugation. It contains a gel barrier that separates the serum from the clot during the centrifugation process, allowing for easy collection of the serum layer.
The purpose of a serum separator in a blood collection tube is to promote the separation of blood components. It contains a gel that forms a barrier between the serum and the blood cells when the tube is centrifuged. This allows for easy isolation and extraction of the serum for testing purposes.
A FBS (Fetal Bovine Serum) collection tube is used to collect blood samples from animals for various laboratory tests. These tubes contain a special coating that helps prevent clotting and preserve the serum for analysis. After collection, the blood is usually centrifuged to separate the serum for further testing.

A complete blood count (CBC) is typically performed on whole blood, which includes plasma and cellular components. Serum is the liquid component of blood that is collected after the blood has clotted and the cellular components have been removed. So, a CBC is not performed on serum specifically; it is typically performed on whole blood samples.
A plain red-top tube without anticoagulant is typically used to collect serum samples for laboratory testing. The tube allows the blood to clot, which separates the serum from the cellular components.
A serum separator tube is a type of blood collection tube that contains a gel at the bottom to separate blood cells from serum during centrifugation. After spinning, the gel forms a barrier between the serum and the blood cells, making it easier to collect and analyze the serum for various tests.
Plain red top tubes do not require mixing at the time of collection. These tubes contain no additives or anticoagulants and are used for serum collection.
