Dear Simon,

In Máxima Medisch Centrum we use 1 liter Dewar containers filled with fine sand. Sand makes the handling much easier compared to water when using barcode labeled tubes. These containers with the appropriate tubes are permanently stored in a stove at 39°C. After collection of the sample the containers are placed in the stove again for the blood to coagulate. Then the serum is prepared in a heated centrifuge.

Kind regards

Dear all,

 

To get our cryoglobulin service UKAS accredited we need to document the temperature of water that we give out to users when they collect a flask from the lab as well as the temperature of the water at the point the flask comes back with the sample in it. Is there any guidance on how warm a cryo can be without causing any issues? It can take a little while for the flask to go out to the patient, and come back to the lab so we will need to send out water a fair bit warmer than 37 to ensure that it is not less than 37 when it comes back, the question is what temperature can we send out?

 

I know some labs take the warm flask to the patient themselves to ensure the tube remains warm throughout, but unfortunately due to the nature of our network of hospitals that is not an option without having a dedicated member of staff to travel around London and a company oyster card!

 

Thanks,

 

Simon
