Transfusion Medicine

    Dr Shirley Phyllis Owusu- Ofori

                       Head of Unit

The Transfusion Medicine Unit (TMU) provides blood transfusion support in terms of blood and blood components for clinical use in Komfo Anokye Teaching Hospital and other health care facilities in the Ashanti Region and beyond. The Unit seeks to provide a steady regular supply of safe blood to patients requiring blood as a therapeutic intervention. Established in 2002, the Unit operates under the Medical Director’s ambit.

The TMUis headed by Dr Shirley Phyllis Owusu- Ofori (nee Opoku), a Transfusion Medicine Consultant.


Other management team members are:


Technical Head – Labs Section               Dr. Francis Sarkodie

Head – Donor Care Section                    Ms. Stella Manu

Head – Donor Organisation Section       Mr. Kwame Asenso Mensah

Administrative Manager                          Ms. Alice Antwi


Currently, 80% of total blood collections in KATH, emanates from voluntary non-remunerated blood donors with a repeat voluntary donor population of 30%.

The unit continually strives to increase voluntary blood donations and has initiated a drive to convert family replacement donors into altruistic voluntary donors.



a. Donor Organization


The TMU offers services including Donor Organization which involves the planning of mobile blood collecting sessions, recruiting and retaining voluntary blood – donors, attracting new areas i.e. work areas, groups etc for blood collection.


b. Laboratory Services

Transfusion–Transmissible Infection screening assays namely anti-HIV, HBsAg, anti-HCV and Syphilis antibody tests are carried out under quality-assured means on all blood units for patient care.

Immuno-haematology services include Blood grouping serology for both patients and donors, Compatibility testing of blood units for patients, Antibody investigations and Investigations for adverse transfusion reactions.

Blood and Blood components provided by the unit are Concentrated Red cells, Whole Blood, Fresh Frozen Plasma, Cryoprecipitate and Platelet concentrates.




c. Donor Clinic


The Donor Clinic offers Pre and Post Donation Counseling to prospective and deferred blood donors respectively. Therapeutic Venesections are carried out for referred patients. Pre-Operative Autologous Blood Donation services are available for well-informed elective patients from either of the surgical disciplines. It is very much encouraged that this service will be patronized tremendously to reduce over-reliance on allogeneic blood.



The TMU assists clinical care with appropriate use of blood guidance on a daily walk-in basis. Consults are available also for Transfusion related clinical issues and the management of special transfusion related cases. A Haemovigilance program has been initiated with the support of Terumo BCT and JICA in three departments; Oncology, Paediatrics and Obstetrics and Gynaecology. The ultimate goal is to roll it out successfully across all the Clinical Departments in KATH.



The Transfusion Medicine Unit continues to play a vital role in the In-service training of most categories of health workers on Blood related issues such as Procedures for Requesting Blood, Collection and Storage of Blood, Administration etc. The unit has trained several batches of Phlebotomists who render quality services across the hospital to relieve clinical areas and laboratories of the pressure of long waiting times for clients and donors.


The unit also plays a vital role in the induction training of Intern doctors and pharmacists by introducing them to the basic rudiments of a safe transfusion practice. Practical support is offered to students training and preparing towards their Bachelor of Science degree in Medical Laboratory Technology. Part-time teaching of Clinical Medical students in Transfusion Medicine is also offered by the unit.

The unit has contributed over the years in building research capacity and providing local blood transfusion evidence in Ghana and Sub-Sahara from several studies carried out. Several international institutions who have forged strong research collaborations with the unit include Division of Transfusion Medicine, Department of Haematology of the University of Cambridge and Liverpool School of Tropical Medicine, Liverpool. Organizations like Sliagen LLC, Austin, Texas and recently Terumo BCT Inc, Europe have had fruitful research engagements with the Transfusion Medicine Unit in carrying out research activities aimed at improving blood safety.  A landmark clinical trial, African Investigation of the Mirasol System (AIMS) was conducted with Terumo BCT and it was demonstrated that the transmission of malaria through blood transfusion could be significantly reduced using the Mirasol technology. As a result of this study the Mirasol Whole Blood (WB) system was CE marked in September 2015. This has culminated in the implementation of the Mirasol Whole Blood Pathogen Reduction Technology in two teaching Hospitals (Korle-Bu and Komfo Anokye) in Ghana.
