When you use extended sample expiration, how does this affect electronic crossmatch? The sample collection date would cause our LIS to reject the EXM rule. Do you just perform IS serological crossmatches?

We do 21 days.

We extend for 14 days.

We do 7, but this facility did 14 days about 10 yrs ago. 
I've also worked at a facility that did 30 day samples.  As long as you have a clear policy I believe it's up to your discretion but I haven't seen anything greater than 30 days.

We do a week vs 3 days.  RRay is correct.  It is up to you to determine how long.

We do up to 30 (33 actually) days.  If sample collected 1/21/23 and surgery is 2/21/23 - we set exp of sample to 2/21/23.  On DOS if all documentation is rec'd from OR - then extend 3 more days.
