FDA
Issues Regulations on Human Cells, Tissues, and Cellular and Tissue-Based
Products; Donor Screening and Testing, and Related Labeling- Testing
Requirements are Modified for Egg Donors and Embryo Donors
The FDA has issued regulations modifying the donor eligibility final rule and the current good tissue practices final rule.
All of these rules will take effect May 25, 2005.
The
new regulations remedy the concerns we had about the timing requirements
for infectious disease testing for egg donors and the testing requirements
for couples who complete their families and then decide to donate their
remaining embryos to another infertile couple.
For
Egg Donors:
The new regulations permit the collection of a specimen for testing an
egg donor for infectious diseases up to 30 days before her retrieval.
This change allows testing to be completed prior to the donor
beginning her ovarian stimulation and relieves the donor, recipient, and
doctor of the worry that the testing (originally required to be within
seven days prior to the retrieval) might have to be repeated several times
if the retrieval were delayed or that results might not be available if
the timing of the retrieval were to be moved up.
For
Embryo Donors:
The new regulations add an exemption from screening and testing for
cryopreserved embryos that, while originally exempted from the donor
eligibility requirement (because donors were sexually intimate partners)
are later intended for anonymous or directed donation.
This change allows couples who complete their families to donate
their remaining frozen embryos to other infertile couples even though they
did not undergo screening tests at the time their sperm and eggs were
recovered. The new rule
requires that appropriate measures be taken, when possible, to screen the
donor couple before transfer of donated embryos to the recipient.
When screening and testing take place after the embryos are frozen
and before transfer to a recipient, labeling requirements apply and the
recipient must be advised that screening and testing of the donor(s) were
not performed at the time of cryopreservation of the reproductive cells or
tissue, but were performed subsequently.
If screening and testing of the donor couple are not performed, the
labeling requirements call for the embryos to be labeled, “NOT EVALUATED
FOR INFECTIOUS SUBSTANCES” and “WARNING: Advise recipient of
communicable disease risks.” The
treating physician would then discuss the potential risks with the
recipient of the donated embryos.
