Our Specialist Courier Services
Every sample we transport represents a life, a hope, a future family or a patient in urgent need. We hand-carry each one with certified cryogenic equipment, complete chain of custody documentation, and the care it deserves.
International Embryo Transport
Your embryos are not freight. They are the result of IVF cycles, hormone injections, clinic appointments, and years of hope. Every Embryo Links courier carries them with exactly that understanding — as a personal responsibility, not a job.
We hand-carry embryos in validated cryogenic dry shippers at −196°C, always in the aircraft cabin and never in the cargo hold. Our couriers hold UN3373 qualification and we coordinate and track all clinic-to-clinic logistical paperwork, support Third Party Agreement preparation and — for international transfers — liaise with clinics on export licensing requirements.
We specialise in UK–EU and UK–Iran routes, and transport embryos to over 30 countries. Every transfer receives WhatsApp updates at collection, departure, arrival and delivery.

−196°C Continuous
Validated cryogenic dry shippers with 10-day hold times maintain temperature from clinic to clinic — no interruption, ever.
Cabin Carry Only
Your embryos fly in the aircraft cabin with our courier — never in the hold. This is non-negotiable, every time.
Complete Documentation Pack
Every transfer travels with a full courier pack — No X-Ray letters, airline approvals, customs release documents, and chain of custody records coordinated for every job.
X-Ray Avoidance
We prepare full airport security letters and request manual inspection at every departure — established protocols at all major UK and EU hubs.
Dual-Witness Protocol
Two independent witnesses verify embryo identity at both collection and delivery. Chain of custody is complete, documented and unbroken.
WhatsApp Updates
You receive a message at every key stage: collection confirmed, en route, arrived, delivered. You always know where your embryo is.
UK-created embryos exported to EU clinics now require an HFEA export licence — a process that typically takes 4–8 weeks. We guide you through this administrative journey and coordinate closely with your clinic's regulatory team, but please start the conversation early. Don't contact us two weeks before your treatment date if international export licensing is required.
How It Works — Step by Step
Consultation & Planning
We liaise with both clinics, track documentation requirements, and coordinate all transport paperwork — Third Party Agreements, shipping manifests and export documentation checklists.
Clinic Collection
Our courier arrives with a pre-charged dry shipper. Embryo identity is verified using dual-witness protocol with the releasing embryologist before anything moves.
Cabin Transport
The courier carries the sealed dry shipper through security (with manual inspection), boards the flight, and keeps the vessel with them throughout — no hold, no exceptions.
Delivery & Handover
The dry shipper is handed directly to the receiving embryologist. A second dual-witness verification completes the chain of custody. You receive your delivery confirmation message.
Frozen Egg Transport
Human eggs are the most fragile reproductive cells we transport. Vitrified oocytes must be maintained at −196°C from the moment they leave the originating embryologist to the moment they reach the receiving clinic — any temperature excursion risks irreversible damage that can't always be detected until the eggs fail to survive warming.
We work with women transporting their own frozen eggs, fertility preservation patients, and egg donation recipients receiving donor oocytes from licensed UK or international egg banks. Each journey has different regulatory requirements — HFEA Third Party Agreement, current patient consent, and for international transfers, HFEA export licensing.
We check consent validity before confirming every transport date, because discovering a consent gap on collection day is a problem no one needs. This is part of the service, not an extra.
Get a QuoteMost Fragile Specimen
Oocytes are more temperature-sensitive than embryos or sperm due to their meiotic spindle structure. There is zero margin for a temperature excursion during transport.
Validated Cryogenic Equipment
We carry oocytes only in medically validated dry shippers at −196°C. The vessel is pre-charged correctly and sealed at source — not opened until it reaches the receiving embryologist.
Consent Verification
We verify that patient consent is current and covers transport to the intended receiving clinic before confirming any collection date. Consent from several years ago doesn't always cover a new situation.
Own Eggs & Donor Eggs
We transport fertility preservation samples, eggs from previous IVF cycles, and donor oocytes from licensed UK egg banks — each with the correct regulatory documentation for the specific situation.
UK to Spain, Greece & Beyond
We manage UK–EU oocyte transport regularly. Post-Brexit HFEA export licensing, Spanish and Greek import requirements — we know the paperwork for each route.
80–90% Survival Rate Maintained
Correctly managed transport does not reduce egg survival rates after warming. The eggs arrive in the same cryogenic state they left in — the biology at warming reflects the quality of the eggs, not the quality of the transport.
If you are receiving donor eggs from a clinic in Spain, Greece or the Czech Republic, the UK HFEA's rules on anonymity and donor limits may differ from the regulations in the originating country. Your receiving UK clinic should advise you. The physical transport is straightforward once the documentation on both sides is confirmed — and we manage that process for you.
Sperm Sample Transport
Sperm transport spans a wide range of clinical scenarios — men banking before cancer treatment, couples relocating their stored sample to a new IVF clinic, fertility clinics receiving donor batches, and men whose surgically retrieved sperm (TESE or PESA) needs to move from an andrology unit to an IVF clinic, sometimes on the same day.
Frozen sperm stored at −196°C maintains quality indefinitely when temperature is uninterrupted. The consequences of a transport failure for a cancer survivor with banked sperm, or a man with a small TESE yield, are irreversible. We apply the same cryogenic standards and chain of custody documentation to every sperm transport, regardless of sample size.
Our quality management system is ISO 9001 certified. Each transfer is supported by a complete courier documentation pack — chain of custody records, No X-Ray letters, airline approvals, and customs release documentation at every transit point.

Cancer Banking Transport
We regularly transport banked sperm for patients who stored samples before cancer treatment. These samples may need to move years or decades later — we handle every stage of the documentation.
Same-Day TESE/PESA
Surgically retrieved sperm sometimes needs to travel from an NHS andrology unit to an IVF clinic on the same day. We have same-day collection and delivery available across all UK urban areas.
Donor Sperm Distribution
We transport donor batches from licensed UK sperm banks to recipient clinics, with full chain-of-custody traceability documentation included as standard.
ISO 9001 Certified
Our quality management system is independently audited and ISO 9001 certified. Incident reporting procedures align with HFEA requirements. All records available for inspection.
International Sperm Transport
We regularly work with Nordic sperm banks distributing to UK clinics and UK clinics exporting internationally. HFEA import/export administrative coordination support, UN3373 packaging and customs documentation all included.
Complete Documentation Pack
TPA, consent documentation, straw identifiers, transport manifest, chain of custody log, delivery receipt. Every document prepared, signed and retained.
At collection, the releasing embryologist or andrologist and our courier independently verify the patient identity, straw identifiers, and dry shipper condition — both sign the manifest. The same verification is repeated on delivery. This is standard practice, not an optional extra, and it is one of the most important questions to ask any biological courier.
Stem Cell & Cord Blood Transport
A vial of haematopoietic stem cells may be the only available HLA-matched transplant unit for a patient in urgent need. A cord blood unit stored at a private bank represents years of premiums and a family's biological insurance policy. A fresh bone marrow harvest has a window of hours, not days.
We handle all main stem cell product types: cryopreserved HSC and cord blood units at −196°C; fresh apheresis products and bone marrow harvests at +2–8°C with tight timing requirements; and advanced cell therapy products including CAR-T cells on both the outbound and return legs of the supply chain.
Our operations team is available 24/7 for stem cell and cord blood transports — collection schedules are set by clinical teams, not courier preferences. Digital temperature logging is deployed on high-value transports to provide the receiving transplant centre with a continuous temperature record.
Get a QuoteCryogenic at −196°C
Frozen HSC, cord blood and cell therapy products travel at −196°C in validated dry shippers with temperature logging. Any deviation is grounds for product rejection — we maintain the standard, every time.
Fresh Products at +2–8°C
Apheresis HSC products and bone marrow harvests travel in validated refrigerated containers. Fresh bone marrow must reach the transplant centre within 24 hours — we plan every route to meet that window.
24/7 Availability
Bone marrow harvests don't happen at convenient times. Our operations team is contactable around the clock for stem cell transports — there are no exceptions to this.
CAR-T Cell Supply Chains
We handle both legs of CAR-T cell supply chains — the patient T-cell collection to the manufacturing site, and the modified cells back to the treating centre, often across international borders.
Cord Blood Banking
We work with both private family cord blood banks and public transplant registries for unit release and transplantation transport. The stakes are high — our standards match them.
Digital Temperature Logging
High-value and time-critical transports are equipped with calibrated electronic temperature loggers providing a continuous record. The receiving transplant centre gets full temperature history on arrival.
Unlike many pharmaceutical products, cryopreserved stem cells cannot be assessed after a suspected temperature excursion. A cell viability assay may look normal even after damaging devitrification — the damage affects engraftment capacity, not simple cell viability. A functionally compromised cell looks identical to a healthy one until it fails to engraft in the patient. This is why there is no "risk-based decision" available for a temperature breach with cryopreserved stem cells. Prevention is the only option.
Cold Chain Transport for Vaccines & Biologics
Cold chain is not one thing — it spans more than 200°C, from standard refrigerated +2–8°C through to cryogenic −196°C. A service equipped for standard vaccine transport is not set up for −80°C ultra-low biologics, and neither can handle cryogenic cell therapies. We cover all four temperature ranges with the right equipment and documented validation at each level.
Most cold chain failures are invisible. A vial that's warmed and been re-cooled looks identical to a correctly handled one. Only a validated, continuous temperature record provides evidence of product history. Our operations are GDP-aligned and ISO 9001 certified — all temperature records available for regulatory audit.
We transport conventional vaccines, monoclonal antibodies, gene therapies, investigational medicinal products for clinical trials, and hospital-to-hospital biological medicine transfers — with same-day collections available for urgent requirements.
Get a Quote
Conventional vaccines (influenza, hepatitis, HPV, MMR), monoclonal antibodies (adalimumab, trastuzumab, rituximab), insulin, most biologics.
Varicella vaccine (Varivax), certain diagnostic reagents, biological reference standards. Must not be taken lower — −80°C conditions will take them out of specification.
mRNA vaccines (Pfizer-BioNTech), advanced biologics, clinical trial IMPs. Transported in dry ice with IATA PI 954 compliance. All couriers hold current IATA DG training.
Cell and gene therapy products, haematopoietic stem cells, CAR-T cells, embryos, oocytes. Entirely different equipment and protocols from conventional cold chain.
GDP-Aligned Operations
Good Distribution Practice compliance with full documentation: temperature logs, chain of custody, delivery receipts. Independently audited, ISO 9001 certified.
Clinical Trial IMP Logistics
Investigational medicinal product transport with ICH-standard documentation and MHRA inspection-ready records. Continuous calibrated temperature logging for every IMP movement.
Hospital-to-Hospital Transfer
Surplus vaccine redistribution, biological medicine inter-site transfers, clinical trial site deliveries — same-day collection available for urgent requirements across all UK urban areas.
UK batch release requirements and MHRA licensing are now separate from EU GDP requirements. Products crossing the Channel need to satisfy both frameworks. If you're moving biological products between UK and EU clinical sites, speak to us before assuming a cross-Channel supply chain is straightforward — it usually isn't, and the paperwork needs to be right before the product moves.
Clinical Specimen Transport
Different specimens have very different rules — and getting them wrong is a common cause of rejected, delayed or clinically useless results. EDTA blood for a full blood count tolerates a day at room temperature. A citrate coagulation sample gives unreliable results if it's been sitting in a warm vehicle for four hours. A blood culture needs to stay warm, not cold. CSF must reach the microbiology lab fast and must not be refrigerated.
We run both scheduled daily collections from GP surgeries and private clinics, and on-demand same-hour collections for urgent or time-critical specimens. All packaging is UN3373 compliant. All specimens travel in validated, temperature-appropriate containers — not a catch-all cool box.
We work directly with requesting clinicians, GP practices, private hospitals and reference laboratories. Every run gets a documented collection manifest. Patterns of missing or late specimens are flagged proactively — we don't wait for the lab to complain.
Get a QuoteBlood Samples
EDTA, SST, citrate, lithium heparin, fluoride oxalate — each tube type has a different stability window and temperature requirement. We handle each correctly, not all the same.
Tissue Biopsies
Formalin-fixed biopsies for histopathology, fresh tissue for frozen sections and cytogenetics, intraoperative specimens requiring same-day path lab delivery — all handled with correct temperature and timing.
CSF — Priority Handling
Cerebrospinal fluid for microbiology must not go in the fridge and must arrive fast. Cells deteriorate within 30–60 minutes. We treat CSF as a priority collection. If you have one that needs to move, call us directly.
On-Demand in 60 Minutes
Urgent or time-critical specimens — STAT coagulation, fresh biopsies, emergency microbiology — collected point-to-point within 60 minutes across most UK urban areas.
Scheduled Daily Collections
Fixed morning collection times for GP surgeries and outpatient clinics — timed to end of phlebotomy sessions for same-day routine results. Consistent, punctual, every working day.
UN3373 Compliant Packaging
All clinical specimens travel in UN3373 triple-layer packaging. We supply compliant packaging to all clients and can walk your practice staff through correct technique — five minutes, part of the service.
Temperature Reference by Specimen Type
UN3373 triple-packaging requirements apply to all clinical specimens transported by road or air in the UK and internationally. A clinical courier who does not provide UN3373 compliant packaging is operating in breach of dangerous goods transport regulations — and if an incorrectly packaged specimen causes an incident, liability may rest with the sender as well as the courier. We supply compliant packaging and can train your practice staff in correct technique, included with your service agreement.
