which is the most suitable case ?
The first case, check blood type and Antibody screen waiting asked the doctor for blood and give blood without checking x - matching examination if  Antibody screen negative
The second case, do Cross Matching for every  unit asked the doctor prepared:angered:

So, if I understand correctly, you are asking whether it is OK to give un-crossmatched blood if your antibody screen is negative?  Is that right?  Well, that would depend on a number of factors like: (and this list is not exhaustive)

What do your local guidelines say?

How many samples have you tested for the blood group on the patient?  How are the results documented?

How sure is the blood group of the donor?

How appropriate are your antibody screening cells for the population you are testing?

That's a start

I don't think that there is any single correct answer to your question emadlabs.

Whether or not you can perform a type and screen, and then giving blood without a crossmatch depends upon many factors for it to be a safe method.

Firstly, it depends upon the ethnic mix of both your patients and your donors.  IF these are very similar, then it may well be safe.

However, this safety of doing this also depends upon whether your screening cells express all of the antigens commonly found amongst these ethnicities.  For example, the Dia antigen is comparatively common in The Peoples' Republic of China and, because anti-Dia is a clinically significant antibody, their screening cells should express this antigen, but in the UK, the antigen is virtually never expressed, and so our screening cells, which do not express the Dia antigen, and so our screening cells would be "dangerous" if used in China.

Although when this technique was first mooted was before automation was common, it is now considered to be "dangerous", unless the ABO and D typing, as a minimum, are performed by automation, and the results transferred to a computer system with no human interference, and certainly no human alteration to the results.

Not being familiar with the situation in Jordan, therefore, I cannot answer the question with any authority.

In Jordan The law prohibits the withdrawal of blood from non-citizens who do not have a national number , And often the patient's relatives and friends are donating his blood when acting surgery , We in Jordan  give foreign patients blood without blood donation

and we Spend 5,000 units of blood a month and be very few cases of incompatible blood from 0 - 3 % or  6  cases  in The worst conditions

we do cross matching for every unit prepared

when we take any order for transfusion blood  first we do blood group and Rh factor

for some patients ( Kidney failure و Thalassemia و sickle cells anemia ... etc ) we do phenotype for patient and give filtered RBCs

We do cross matching for units  

 Each unit of blood must be free of infectious diseases by blood, such as AIDS و hepatitis B و C و syphilis and anti-core
