What people get wrong choosing a shipper, from patient threads and the news
Every failure below happened in the hand-offs: a driver with other stops, a parcel network, a tank on a tarmac. None of them happened in a courier's lap.
The "premium" courier was a driver with other stops
The mistake: Paying about $1,000 for a premium tier and getting a driver who arrived before the lab had packed the tank and left without the embryos. Nobody told the patient; she found out by calling the clinic.
“He double-parked in Manhattan, ran in like a DoorDash driver, and when the tank wasn't ready, he left the embryos behind.”Reddit r/IVF (210 points): read the source
How to avoid it: The courier confirms the lab's pack-ready time, stays on site until hand-over, and calls you at every milestone. That is what a dedicated hand-carrier is.
One person, one tank, door to door →Embryos lost in a parcel network for four days
The mistake: Letting a clinic book a third-party parcel courier. The canister sat at a sorting facility and was returned three days later while the two clinics blamed each other over packaging.
“They said, 'We don't know where they are. They should have arrived. They might be in the lab'.”Nine News, Australia (Melbourne to Brisbane): read the source
How to avoid it: One party owns the shipment end to end with a named courier and a phone number, and you are told at pickup, at each hand-over and at delivery.
Our chain of custody protocol →The receiving lab refused a late tank while the temperature was rising
The mistake: A cargo delivery landed outside the lab's intake window and the shipper asked the patient to negotiate an exception.
“the lab refused to accept the embryos because it was 'late'? Cryoport calls me asking if I could call the lab and ask for an exception. They tell me the temperature on the embryos is going up”Reddit r/IVF: read the source
How to avoid it: Confirm the receiving lab's intake hours and a named embryologist before dispatch, and route to land inside that window with hold-time margin.
How we schedule against lab hours →A forklift through a tank on the tarmac
The mistake: Unaccompanied cargo is handled as freight. A journalist who moved her own eggs reported one shipper's tank destroyed by a forklift at Montreal airport.
“a tank was sitting on the tarmac at Montreal airport and a forklift accidentally drove right through it”MIT Technology Review (2022): read the source
How to avoid it: Cabin hand-carry keeps the tank with a person at every moment. That is the whole difference between the two methods.
Hand-carry versus cargo, point by point →When the network shipper paused a whole state overnight
The mistake: Assuming a large shipper will always be available. After the February 2024 Alabama ruling the main network shipper paused all activity in the state within a week and patients mid-cycle had no way to move embryos out.
“Now, even if I wanted to get them out of the state and do a transfer in another state or where my surrogate lives, I can't.”NBC News (Alabama patient, February 2024): read the source
How to avoid it: A hand-carry courier can move when the networks stop. Keep a courier relationship and your own copy of the storage inventory before you need either.
