Hygiene monitoring in a hospital immunohaematological laboratory.
OBJECTIVE
Not only in blood donation services, but also in the immunohaematological laboratory of a hospital including the depository for blood products a hygiene plan must be drawn up and its realization has to be documented.


METHODS
From 2011 to 2014, some equipment in the depository and in the immunohematological laboratory was microbiologically monitored once a year. The examinations were done by direct contact cultures taken from several places of each device.


RESULTS
Most of the devices showed inconspicuous numbers of environmental microorganisms. Sometimes the refrigerators for fresh frozen plasma and a transport container for blood products revealed moderately, the incubator in the laboratory and a transport container for patient blood samples inadequately increased bacterial contamination.


CONCLUSIONS
Microbiological examinations can detect critical points in the immunohaematological laboratory of a hospital. By communicating these results, the staff can be motivated to observe the regulations of the hygiene plan.
