Our blood bank is a unique establishment spread across four floors within the historic, heritage-protected house 10 of the LKI. We have many different departments here, all responsible for specific things, and each has a department head.

The blood bank's platelet production laboratory is on the ground floor. Here, the apheresis and pool platelets are pathogen-inactivated, labelled, and then sent electronically to the immunohaematology lab (and, of course, physically taken there).

Floors one to three belong entirely to the blood bank.

On the first floor, we have the donor ambulance. In this vital service, voluntary donors, our community heroes, come to donate blood, and mainly platelets.

The outpatient therapy area is separated from the donors by the staircase. Patients are treated with apheresis procedures if they are mobile enough to come themselves. If this is not the case (such as with Gullian-Barré syndrome), we drive the apheresis machine to the patient on the ward.

The most common therapy we perform on-site is photopheresis. 

The donor and therapy outpatient departments have the most real contact with either donors or patients, which is the exception in our profession.

The last separate area on the first floor is the component separation - this is a clean room. The whole blood is centrifuged and then separated into erythrocytes, plasma and buffy coat. Five buffy coats are used to make a pooled platelet concentrate.

All the laboratory facilities are located on the second and third floors. 

On the second floor is the infectious serology unit, where the donated blood is tested. Actually, not directly the finished blood units, but blood samples from the donors taken as part of the donation.

Next to it is the immunohematology lab, where the reception and processing of the orders and blood product distribution occur. Our supply area covers the entire Tyrol. Routine samples are processed here: blood grouping, antibody screening, and patient compatibility testing. We always have between 100 and 300 reserved blood units on the stand. These units have been prepared for operations - they have already been crossmatched with the patient's serum and tested for compatibility. They can be sent to the operating theatre by pneumatic tube within minutes if necessary. 

The cold storage for the red blood cell concentrates is also located here. There is also the blood group laboratory, where the results are validated, discrepancies are clarified, and manual testing is carried out, e.g. for infants. In addition, the donor samples are immunohaematologically tested here. For first-time donors, the blood group is determined from two separate tubes. In the case of rhesus-negative donors, additional tests are also carried out to completely rule out the possibility that a donor does express the rhesus antigen weakly. However, he is rhesus negative in routine examinations.

A cross-check with the previous donation is always made - in the case of discrepancies, these must be clarified before a product can be released.

In the special and pregnancy laboratory, all abnormal samples are investigated, and special tests are carried out that are not routinely done on everyone. These include antibody differentiation, elutions and crossmatches for platelets (MASPAT). And as the lab name suggests, samples from antenatal care are tested here.

On the third floor, you can find the office of our institute director, a seminar room, the quality management office, and the IT department. Also located on this floor is our HLA/immunogenetics laboratory and the biologists who work there. The HLA lab is responsible for typing patients and potential donors (for kidney, bone marrow, liver) before transplants, as well as testing and identifying HLA antibodies post-transplantation to help detect humoral rejection in a timely manner. Additionally, our HLA/immunogenetics laboratory is equipped to conduct a wide range of molecular tests, including genetic blood group determination, fetal rhesus diagnostics, and more.

And now, it should become clear that a transfusion physician also has much to do. 

My work focuses mainly on immunogenetics - i.e. the HLA laboratory.
