hello everybody. I'm so happy to join in your community. From now on, here is where I can learn something new and share experience .Thanh you very much

Hi and welcome to Bloodbanktalk:wave:

Welcome to BBT.

I am woking in the bloodbank of a cardiology hospital . I'm in charge of collecting blood and providing blood and blood products for heart surgery case.

In Vietnam, almost hospitals do not perform minor crossmatch with packed cell transfusion . I would like to know if that is right and any of you in US other coutries omit minor crossmatch as we do. I am looking forward to your relies. Thank you in advance.

Welcome Paulis - are you referring to computer matching?

Eion

we are referring gel card matching. Can you tell me some experience on minor crossmatch .thank you very much

Ah, I think I am on to your wave length. I presume you mean donor plasma against recipient's red cells. This was dropped in the mid 1970's by most blood banks. The benefit is small. Donors are well screened for allo-antibodies at the time of donation. However we only transfused plasma depleted red cells - Packed red cells or PRBC. You will encounter HLA related antibodies and Anti-IgG if your are using a lot of products (Plasma, FFP, Platelets etc) but there are ways of dealing with them. A good reference for approach to any Transfusion Reactions you may encounter can be found on the web at www.BBguy.org Good luck with all. Eoin

Eoin,Thank you for your reply. I like the website you point me very much. In vietnam, the technology is really so backward !. We are argueing if we drop the performance of minor crossmatch or not. Because ,our blood bank do not perform allo-antibody screening on donors. Is it neccesary for us to perform minor crossmatch or we drop it. We really want to drop minor crosmatch for the reason of avoiding wastage of gel card and We can shorten the time for crossmatching. I am looking forward to your advice. thank you very much.

In the absence of donor screening and if you are transfusing whole blood, you may well have to continue with the minor - or batch antibody screen your donor blood when recieved. You probably do not have another option as you will surely one day find the patients own cells haemolysing when he gets an antibody to an antigen on his own red cells. Sounds like you need some pressure on your blood suppliers.

Good Luck Eoin

Thank you for your advice, Eoin. My hospital does not receive blood from suppliers. We colect blood from donors who are patient's ralatives and friends.Donors are not screened for allo-antibodies. We are transfusing both packed RBC and whole blood ( fresh blood) for the heart surgery patients. We have done both major and minor crosmatching for whole blood and packed RBC. We plan to do only major crossmatch for packed RBC, but we have hesitation and wonder if anyone does as we do and if that's safe for the patient. What's your own opinion? Thank you.

Paulis, You may have no option but to continue with the minor crossmatch in that case. You could consider a risk-analysis by looking back at records and see if you have encountered antibodies in the minor X/M in the past. This doesn't guarantee that you won't have a problem in the future though. I was interested from the donor point as well. I worked in a trauma centre in Australia with a surgeon who would round up trauma patient's family and friends if the patient had used a lot of blood, components or products and get them to donate. This was just in to the general pool donor pool though and would be tested as normal (HIV, Hep B, Grouped and Screened etc). We discouraged this though as we felt it may put peer pressure on family members to donate and they may lie about sexual history, HIV, past Hepatitis etc. It is very unfortunate that there is not a blood donor program and testing centres in your country. Red Cross have blood establishments in many countries and senior Haematologists (Transfusionists) could perhaps approach them. Anway, that is another story and all I can say is good luck with it all. Kind Regards, Eoin
