When aliquoting a sample from an SST tube, what is the correct procedure?

The correct procedure when aliquoting a sample from an SST (Serum Separator Tube) involves drawing up only the required amount of sample. This practice is crucial to ensure that the aliquoted specimen is of good quality and that there is minimal disruption to the remaining sample in the original tube. By taking only the necessary volume, you can avoid contamination and reduce the risk of altering the composition of the serum, which can occur if excess fluid is drawn, leading to potential inaccuracies in test results.

Proper aliquoting technique is essential for laboratory accuracy and reliability. Drawing the accurate volume helps maintain the integrity of the serum and prevents wastage of valuable sample material, especially when dealing with limited specimens or precious materials in clinical settings.
