Dear Mr. Campbell:

In our July 26, 2005 biologics license applications approval letter for the Blood Grouping Reagents and Anti-Human Globulin listed below, the dating period was stated to be 18 months from the date of manufacture and the date of manufacture was defined as the date of filtration.

Upon review of the approval letter, you notified us on behalf of Biotest AG, that the date of manufacture defined in our letter was not consistent with the information in the BLA submission. Based on the information in the submission and your clarifications we are issuing the following corrections.

For the Blood Grouping Reagents listed in the table below, the dating period shall be 18 months from the date of filling, i.e., the dispensing of the reagents into the microwells. Please note that this represents an exception to 21 CFR 610.50(a), 21 CFR 610.53, and 21 CFR 660.21(e) which define the date of manufacture and the dating period.
