Description of Products
A plain blood tube, also known as a serum tube or red top tube, is a type of tube used in medical settings to collect blood samples for laboratory testing. It is called a "plain" tube because it does not contain any additives or anticoagulants.
Here are some key features of a plain blood tube:
- Color: The tube is usually transparent or made of glass with a red-colored stopper or cap. The red color signifies that it is a plain tube.
- Material: Plain blood tubes can be made of either glass or plastic. Glass tubes are often used for certain types of tests, while PET tubes are more common in everyday clinical practice due to their safety and convenience.
- Additives: Unlike other types of blood collection tubes, plain tubes do not contain any additives or anticoagulants. The blood collected in these tubes will naturally clot over time, allowing for the separation of serum from the clotted blood during laboratory processing.
- Usage: Plain blood tubes are typically used to collect blood samples for tests that require serum as the primary specimen. Serum is the liquid part of the blood that remains after the clotting process. It contains various components, such as antibodies, enzymes, hormones, and other analytes that can be measured for diagnostic purposes.
- Laboratory processing: Once the blood is collected in a plain tube, it is usually allowed to clot at room temperature for a specified period. After clotting, the tube is centrifuged to separate the serum from the clot. The resulting serum can then be used for a wide range of laboratory tests.
