Precautions and Warnings

  • Always work under hygienic conditions (LAF-bench, ISO Class 5) to avoid possible contamination.
  • Always wear protective clothing when working with specimens.
  • Handle specimens as if capable of transmitting HIV or hepatitis.
  • Ensure that the patient is not sensitized to the antibiotic gentamicin.
  • Standard measures to prevent infections resulting from the use of medicinal products prepared from human blood or plasma include selection of donors, screening of individual donations and plasma pools for specific markers of infection and the inclusion of effective manufacturing steps for the inactivation/removal of viruses. Despite this, when medicinal products prepared from human blood or plasma are administered, the possibility of transmitting infective agents cannot be totally excluded. This also applies to unknown or emerging viruses and other pathogens. There are no reports of proven virus transmissions with albumin manufactured to European Pharmacopoeia specifications by established processes.
