MBL standard serum (human) - 1000 (AU):
All individual sera and the serum pool were tested negative for HBsAg and for antibodies against HIV-1, HIV-2 and HCV.
Blood from 30 healthy donors was collected in flasks without anticoagulant and allowed to clot.
Serum was collected after centrifugation and pooled in a 10-liter flask. After mixing, 1-ml aliquots of the serum were pipetted into 2-ml vials.
Each vial was assigned an MBL content of 1000 AU. The material was freeze-dried and the vials closed under vacuum.
However, as no test method can offer complete security that infectious agents are absent, the calibrators and patients’ specimens should be handled at Biosafety Level 2
as recommended for any potentially infectious human serum or blood specimen in the CDC/NIH manual “Biosafety In Microbiology and Biomedical Laboratories”, 1999.
Solutions containing human serum should be treated as potentially infectious and handled accordingly.
