FDA donor testing timeline: how to schedule egg and sperm donor bloodwork
For FDA donor eligibility testing, plan the blood draw backward from the recovery date. Egg donor specimens can be collected up to 30 days before retrieval, while sperm donor specimens must be collected within 7 days before or after donation, and anonymous semen donors need a retest at least 6 months later. Leave time for shipping and review.
Most donor testing delays aren't about the test menu. They're about timing: a draw that lands outside the window, a kit that arrives the day after the donor's appointment, or a result that comes back after the retrieval was already scheduled. Our earlier guide, what fertility clinics and egg and sperm banks need to know about FDA donor eligibility testing, covers which tests are required. This one is about scheduling them so donor cycles stay on track.
It's educational only, not legal or medical advice. Each establishment makes its own donor eligibility determination and should work from the regulations and its own regulatory advisors.
The windows that drive every schedule
The timing rules sit in 21 CFR 1271.80(b) and 21 CFR 1271.85(d). In plain terms:
General rule: collect the donor specimen at the time of recovery, or up to 7 days before or after recovery.
Oocyte donors: the specimen may be collected up to 30 days before recovery.
Anonymous semen donors: at least 6 months after the date of donation, collect a new specimen and test it again for the required agents. Directed reproductive donors are not covered by this retest rule.
Repeat semen donors: once a donor has been tested and retesting under 1271.85(d) applies, you don't have to collect a new specimen at every donation.
The regulation also requires that the testing be done by a CLIA-certified laboratory (or one CMS has found equivalent), using FDA-licensed, approved or cleared donor screening tests where they exist. FDA's donor testing requirements page lists the specific assay types for each agent.
Planning an egg donor cycle
The 30-day window for oocyte donors is the most generous in the rule, and it's there for a reason: it lets programs finish testing before stimulation is far along. A practical way to use it is to work backward from the expected retrieval date.
Pick the target retrieval date once the donor's protocol is set, and mark the date 30 days earlier. That's the earliest day a valid specimen can be drawn.
Order kits early. Have donor kits at the clinic or with the collecting provider before the draw is scheduled, so a late shipment never pushes the draw.
Draw early in the window, not at the edge. Drawing near day 30 leaves no room if the retrieval moves earlier, or if a sample has to be recollected.
Leave time for results and review. Add shipping time to the lab, the lab's turnaround and the time your responsible person needs to review results and document the eligibility determination.
Recheck the window if the date moves. If a cycle is cancelled or pushed back past 30 days from the draw, plan for a new draw.
Remember that reproductive donors also need chlamydia and gonorrhea testing under 1271.85(c), which usually means a urine specimen collected alongside the blood draw.
Planning sperm donor testing
Sperm donor scheduling looks different because donation is often repeated and specimens are typically frozen and held.
Match the draw to the donation. For each donation that relies on a new test, the specimen must fall within 7 days before or after that donation.
Plan the 6-month retest for anonymous donors. Put the retest date on the calendar at the first donation. Under 1271.85(d), the new specimen is collected at least 6 months after the date of donation, and it's tested for the same agents as the original.
Include the extra agents. FDA's donor eligibility guidance lists semen as a viable, leukocyte-rich tissue, so sperm donors are also tested for HTLV-I/II and CMV under 1271.85(b). Oocytes are not considered leukocyte-rich.
Common causes of redraws and delays
Most of these are avoidable with a checklist:
Draw outside the window. The most common problem, often caused by a retrieval or donation date that moved after the draw.
Wrong or missing specimen. Donor panels need a venous blood draw by a trained professional plus a urine specimen for chlamydia and gonorrhea. Check the kit instructions for tube types and volumes before the appointment.
A test that isn't suitable for donor screening. A diagnostic assay that's fine for a routine patient visit isn't automatically acceptable for donor eligibility. Confirm each assay on the panel meets the 1271.80(c) requirements.
Shipping problems. Weekend or holiday arrivals and long transit times can push a specimen past its stability limits. Ship on days the lab can receive.
Missing paperwork. Incomplete requisitions or donor identifiers that don't match the tubes can stop a sample at accessioning.
When donor testing isn't required
21 CFR 1271.90 lists exceptions, including cells and tissue for autologous use and reproductive cells or tissue donated by a sexually intimate partner of the recipient. Those exceptions come with labeling requirements, and some situations, such as cryopreserved embryos later intended for donation, have their own rules. Check the regulation and your advisors before assuming an exception applies.
Questions to ask your donor testing lab
Before you build a schedule around a lab, ask:
Which donor screening assays do you run, and are they FDA-licensed, approved or cleared for donor screening where required?
Are all donor tests run in your own CLIA-certified lab, or are some sent to another lab?
What is your typical turnaround from receipt of sample, and how are reactive results communicated?
Can you ship domestic, international and bulk kits to our clinic or collecting provider?
What documentation can you provide for our compliance file?
Which days can you receive specimens, and what are the shipping cutoffs?
Putting it together
A donor testing calendar has three fixed points: the recovery or donation date, the collection window around it and, for anonymous semen donors, the 6-month retest. Schedule kits, draws, shipping and review around those points, and recheck the window whenever a date moves.
IHDLab runs FDA donor eligibility panels for egg and sperm donors in its own CLIA-certified lab in Irvine, California, with kits delivered to the clinic or provider for a trained professional to collect the draw. You can see the panels and the regulatory mapping on our FDA donor testing page, along with our fertility and IVF lab services.
