A clot activator tube, typically with a 4 mL volume, is designed for serum collection by facilitating blood clotting before serum separation. Here are some key points:
- Purpose: These tubes are used for tests that require serum, as they promote the clotting of blood samples.
- Composition: The tube contains a clot activator, which can be a silica gel or other substances that enhance the clotting process.
- Color: Clot activator tubes usually have a red or orange stopper, indicating they contain no anticoagulants.
- Usage: After blood collection, the tube should be gently inverted several times to ensure the blood is mixed with the activator, then allowed to sit at room temperature for a period (often about 30 minutes) to allow clot formation before centrifugation.
- Applications: Commonly used for serum chemistry tests, serology, and certain hormone assays.
- Storage: Samples can be refrigerated after clotting and centrifugation, but should be processed within a certain timeframe for optimal results.
