Thank you for the nice video but may I ask why in the 2nd example the reverse grouping is AB and not O, I thought it is O as there is Abs against A1 (1+) cells and B (+4) cells??
The negative in blood group testing is referred to the missing D antigen in on the RBC. I explained the method and procedure in this video th-cam.com/video/0UaiLo6E3Xk/w-d-xo.html. For rouleaux, I explained in this video th-cam.com/video/Q0wEB1z5u8E/w-d-xo.html
Are you referring to patient who has been transfused recently? It depends on the patient age, type of product that the patient was transfused with and how much of that product the patient received. Most of the time, we can tell by looking at the reaction. Also the blood type is not usually change with a unit of RBC (in adult patient), but you may have a discrepancy in the Rh type, especially if you are performing testing using solid phase method. This is when the patient transfusion history will be useful. Example: A patient received 5 units of emergency O negative RBC. A CLS performs a test and the results are forward and reverse type as O blood type, but observes weak reaction for D4 and D5. How would you report the result? The patient did not received any plasma product, so the reverse is reliable. The reverse is O blood type Patient received 5 unit of O RBC and we type the patient as O. There are two scenarios that can happen with this. The patient is really an O blood type patient or the patient is not type O, but now have blood type O due to transfused blood. This can be result by perform another type when the patient in an untransfused state or try again after 24 hours of not receiving blood product. For this example, the patient is probably type O because the forward and the reverse reactions agree with each other (given the patient did not received any plasma product). Patient received 5 units of Rh negative cells. This is show in our test result as weak reaction for D4 and D5. The patient blood type is O pos with weak D4 and D5 reactions due to 5 units of emergency O negative RBC. I hope this helps.

@ 4:59 the reverse: O blood type
Sorry about that guys!
grrrr
Thank you very much! It's very helpful!
😊 thank you.

Yes, correct. You are absolutely correct. I am so sorry for my error. @5:04 the reverse is O blood type.
Very good
Thank you. I have to apologize that the music was to loud on the other previous one.
How to deal incompatible cross match? Please make a video.
Thank you this is a very good idea.
How detect negative blood group & Rolex in RBC.
The negative in blood group testing is referred to the missing D antigen in on the RBC. I explained the method and procedure in this video th-cam.com/video/0UaiLo6E3Xk/w-d-xo.html. For rouleaux, I explained in this video th-cam.com/video/Q0wEB1z5u8E/w-d-xo.html
How about resolution for double population in blood group

I hope this helps.
If patient is not transfused, not a transplant case and still mixed field is found then
you already have PEG..can you show LISS?
Added to my long todo list. 🙏
@@BloodTalks Thanks. I'll subscribe when you post it. 😂
WBC differntisl
I do have a video on that. th-cam.com/video/VoXg55AcM6k/w-d-xo.html
