Collector dates seals, donor initials seals
The collector, not the donor, writes the date on the seals. After the seals are affixed to the specimen vials, the donor is requested to initial the seals.
Note: The collector must not ask the donor to initial the seals while they are attached to the control form. The seals must be initialed only after they are placed on the vials. Inform the donor to use care during the initialing process to avoid damaging the seals.
