Group ABO reactions + and +s

[dboutin]

While in some cases when identifying antibodies it might be interesting to differentiate a regular reaction ex: 1+ than a strong reaction 1+s.

Do you see this importance for ABO-RH grouping or 1+ is sufficient ?

Thanks

It seems splitting the grades is most useful when we want to compare reactions--looking for dosage or a different specificity on a panel, for instance. It doesn't seem like there is much to compare with routine grouping/typing. Maybe in bone marrow transplants where you are watching a patient's type change over time as the graft takes hold it could be useful??? Even then I would think full grades would be sufficient.

We will look A&B antigen weaker than 2+ as weaken, which we will find the reasons, subgroup or illness.

We only grade weak or strong with antibody detection.
