Do you have a top-table centrifuge for 1 mL syringes and access to liquid nitrogen?
Indeed, the HbNO protocol requires access to these equipments within the 15 minutes after blood sampling and before storage at -80°C. Could you double-check with your team the feasability of this preparation please?
In order to secure this measurement, I added these to the "equipment" document stored in the cloud. You can also let me know by email or comment to this post.
Your help would be really appreciated ;) !!!
