Sample storage guidance
Synnovis takes all possible steps to ensure that the integrity of samples is maintained prior to them reaching our laboratories for testing.
All vehicles used by our logistics provider GSG are temperature controlled and we have worked with local phlebotomy services to help them safeguard samples prior to collection. We continue to monitor potassium levels in samples, as this allows us to detect any process anomalies.
This is particularly important during the extreme temperatures associated with changeable UK weather patterns. In the worst-case scenario, excessive heat or cold can lead to invalid results.
Logistics and collection changes
Synnovis takes all possible steps to ensure that the integrity of samples is maintained prior to them reaching our laboratories for testing.
All vehicles used by our logistics provider, GSG, are temperature controlled and we have worked with local phlebotomy services to help them safeguard samples prior to collection. We continue to monitor potassium levels in samples, as this allows us to detect any process anomalies.
The correct storage of samples is particularly important during the extreme temperatures associated with changeable UK weather patterns. In the worst-case scenario, excessive heat or cold can cause samples to degrade, leading to invalid results.
Please follow the below advice when storing samples for collection:
- All samples should typically be stored at ambient room temperature while awaiting collection
- Do not refrigerate blood samples as these can be affected by the cold, leading to spurious results for some analytes
- Urines for microbiology should be collected in boric acid containers, which will ensure they are stabilised in the event of any delay in processing
- Urines and stool samples for biochemistry can be refrigerated if, for any reason, they had to be stored overnight. However, if you are having to store samples for longer than expected, you should contact the Synnovis Customer Services team so that collection arrangements can be reviewed
