Hopefully someone can help confirm the correct ISBT codes to use for Thawed Plasma, frozen within 24 hours. I think....

 

an E2555 (PLASMA|CPD/XX/<=-18C|Frozen<=24h) once thawed becomes an E2701 (Thawed PLASMA|CPD/XX/refrig|Frozen<=24h) with a 24 hour outdate. If I want to extend the outdate to 5 days it appears as if the ISBT code would be E2684 (Thawed PLASMA|CPD/XX/refg).

 

But this is the same product code that I use when I extend an E0773 (Thawed FRESH FROZEN PLASMA|CPD/XX/refg)

 

Am I on the right track?

I would expect the number of both versions of thawed plasma to be the same even though the original product was different.

Yes, you are correct! 

 

Some of the logic behind this: It's like washed red cells:  No matter what Red Cell product you start out with (CPD, CPDA-1, CPD>AS3, etc.), if you wash it in an open system, it converts to the same washed red cells product code with the same 24-hour outdate.  ISBT 128 describes "what's in the bag" not what it started out.  So, if you extend the dating of plasma to 5 days, you have a thawed plasma regardless of whether it started out as FFP, Plasma frozen within 24 hours of phlebotomy, or the newest type of plasma: Plasma held at room temperature up to 24 hours and frozen within 24 hours of phlebotomy.

 

It actually makes it a little easier, I think.

E2684 is what we use
