We have had the same issues and are looking at using gel as our backup instead of test tubes.  We have found in a small comparison so far that most are negative in gel but we have found true antibodies in gel that were negative in PEG and LISS and that gave no apparent pattern with solid phase even with homozygous cells that turned out to be Fy, E antibodies.  I have attached some literature comparing SP to GEL (one includes comparision to PEG).

I have a not-serious question on each of my med tech student quizzes. I thought I'd share a current student's response to "Describe in 80,000 words or less why immunohematology is by far the most interesting department in the lab." I usually get charming BS like "Because Phil is awesome!", but this guy got a little deeper:
 
"While not as engaging as Micro, Immuno, Heme or Molecular on the surface, Immunohematology (aka blood bank) is much more mentally taxing. It requires one to think through a process logically, using the tools at one's disposal in the metaphorical tool box, to produce a resulting reaction one can use to reason an answer to a medically potentially dangerous situation. On a theoretical level, this requirement leads to the utilization of the full extent of one's mental capacity, causing it to be psychologically fulfilling, and therefore the superior department of choice for the intellectual medical lab scientist. Also, the word agglutination is funny."

Sorry I didn't write my question very well
I had found the below article for Managing Recall and Market withdrawals and then had read in the technical manual a reference to FDA blood guidances on infectious disease. Within the article it had Table 3. Suggested Approaches for Follow-up of Blood Components Discovered After Transfusion to Have Been in Nonconformance (Biological Product Deviations).
Outside of Lookback for HIV, HCV, and Chagas, is anyone contacting the physician for recalls/market withdrawals received from your blood supplier of any of the items listed like the Malaria-risk travel and if so what guidelines do you use
