What type of doctors do blood typing or transfusion of blood?

Pathology and laboratory medicine

By definition, a hematologist is someone who studies blood.

(This is also spelled "haematologist" in countries that prefer the British-style spelling.)

Any physician can order a type & cross, irrespective of their specialty when they feel a transfusion is indicated, it's not rocket science, it's a matter of simply monitoring the vital signs and H/H.

The blood bank will do the type and cross and issue as many units as the ordering physician requests.

Phlebotomists draw blood and test it!

pathologists or more specifically haemotologists  are responsible for this

Doctors almost never do blood typing. I work in a major trauma and transplant center where our blood bank does approx 20,000 type and screens / year, of that number I would guess 19,999 were done by lab techs.

All doctors, nurses, and other healthcare professionals- no matter the field- will deal with patients who are in need of blood products. Lab/patho with do a type and screen but it is actually the nurses who administer blood.

hello!Professionals who do blood typing are medical technologist or laboratory technicians...they are not doctors. Doctors are the one ordering the transfusion n order for crossmatching. All doctors can order it but the one who performs the test are not them.

Any doctor can order a Type and Crossmatch and give orders to transfuse a patient.  Hematologists are doctors that deal with various blood disorders - leukemia, anemia, various cancers.  Unfortunately, in my experience, many doctors haven't a clue what is involved with doing a type and crossmatch on a patient -- especailly patients with antibodies or other blood banking issues....  Medical Technologists are the people responsible for doing the actual work to type a patient and find compatible blood that is "safe" to transfuse into a patient....  It is a great job, but can be quite stressful at times.
