Anthony Nolan response to Covid-19

As with many sectors, COVID-19 is causing significant challenges for transplant centres and international registries worldwide.

It is a rapidly changing situation and we’re working hard with partners and suppliers to make sure that stem cell collections for patients are still collected and delivered safely and on time. This has involved some changes to our current processes and these are listed below. If you have questions about any aspect of your service from Anthony Nolan in relation to COVID-19, please contact us on

The Search Team continues to provide searches of the UK aligned registry and the international stem cell donor registries for UK patients as usual. We will provide our Transplant Centres with updates in the event that individual registries are unable to provide search results due to local COVID-19 restrictions. We are also happy to provide assistance with the identification of a UK-based back up donor or cord blood unit(s) should these be required, especially in the case of patients who are at workup for a donation of fresh cells. Please contact your Search Coordinator in the event that you require our help with such cases.

Non-AN Donor VT

Currently, the majority of the international registries are able to provide blood samples for donors requested for VT. NMDP (US) donors are only providing buccal swab samples at the VT stage. If your H&I Laboratory is unable to accept buccal swabs for testing, NMDP are able to arrange for the testing of these samples within their own laboratories; please advise your Search Coordinator accordingly at the time of submitting your VT request for an NMDP donor. In the event that local COVID-19 restrictions prevent additional registries from providing blood samples for VT requests, we will provide updates as soon as we are notified of a change to their VT processes.

Verification Typing (VT) for Anthony Nolan Donors

  • Anthony Nolan is procuring blood samples for VT testing – VTs can be requested as normal.
  • If a donor is unable to provide blood samples, we can instead ask them to provide swab samples and we will perform a pre-VT test at our Anthony Nolan Labs. (Please note: CMV testing is carried out using a buccal swab sample. This is not an accredited process in our laboratory, however, an application to obtain accreditation is currently in progress. Therefore, the result provided is for information only and we recommend confirmation of CMV status prior to final donor selection).
  • We can provide a donor health and availability check free of charge if this your preference.
  • If a donor who has provided swab samples or a health and availability check is selected to continue to workup, VT samples will be taken at medical for a concurrent VT and workup.

Workups and Provisions

To ensure donor and patient safety during this time, our donation polices have been reviewed and the following steps have been taken: 

  • We are following the Public Health England guidance and deferring donors who are identified as being part of a risk category. 
  • Donors are fully screened before attending the collection centre for their Medical and again between Medical and Donation. 
  • Donors are advised to follow comprehensive social distancing for 10 days prior to Donation; this time frame is reviewed regularly as government guidance is updated. 
  • Donors are advised to communicate with us immediately if they develop symptoms at any point of the donation process or are exposed to COVID-19. 
  • Our Health History Questionnaire has been reviewed to include screening for history of or exposure to COVID-19. 
  • Our Donor Follow-Up team are currently calling donors on day 2 or 3, day 7 and day 14 post donation. If the donor reports any COVID-19 symptoms (regardless of whether they tested positive or negative on day of collection), this will be passed on to the Transplant Centre.  

The routine requesting of fresh cells has increased, and we continue to strongly recommend having a backup donor or cord blood unit identified for fresh product requests. Please do contact us if we can support that in any way.  

Requests for cryopreservation for COVID-19-related reasons are still being accepted at this time, provided planned infusion dates are within an acceptable timeframe. If the Transplant Centre is unable to cryopreserve the product, Anthony Nolan can perform this on your behalf and arrange shipment. Please contact your Donor Provision coordinator at the time of workup in the event that you require our help with such cases. 

As COVID-19 cases in the UK have increased, we have started to see an increase in donors either testing positive for COVID-19 or having to isolate due to close contact. We continue to work on all provisions on a case-by-case basis and are regularly reviewing our policies. Last minute deferrals (COVID-19 or otherwise) remain a risk of unrelated stem cell donation. 

With the continued rollout of the vaccine, this may also affect schedules with last-minute deferrals due to donors receiving doses of the vaccine whilst going through the donation process. Deferral periods are being followed as per JMAC guidance.  

Please note DKMS UK does not currently allow Medicals for back-up donors unless exceptional circumstances apply. 

All our UK collection centres are testing for COVID-19 in accordance with NICE Guidelines as per the following: 

  • Donors are tested on the day of the Medical; the result will be marked on the donor clearance along with all other IDM results. 
  • Where product is being cryopreserved, donors are tested on day of Donation (Day 1 for PBSC). The result will only be communicated to the Transplant Centre if positive. We aim to have the result within 24 - 48 hours but this cannot be guaranteed. 
  • If the product will be used fresh, the donor will be tested within 3 days of the patient’s planned conditioning date. The result will be communicated to the Transplant Centre. We aim to have the result within 24 - 48 hours but this cannot be guaranteed. 
  • Where some Collection Centre trusts require additional COVID-19 testing, the result would only be communicated to the Transplant Centre if positive. 

Many international registries are unable to test for COVID-19. The international virology checklist which is completed by the registry at the start of the work up has been updated to including testing for COVID-19. This form will be sent to the Transplant Centre in advance of the Medical and indicate if testing can be performed and at what point in the process – Medical, Donation or both. 

Patient-donor correspondence

  • Donor Follow Up are moving to a hybrid approach for patient-donor correspondence. 
  • Handmade / decorated cards and letters received from donors will be sent to transplant centres by post, to be passed to the patient. 
  • All other correspondence from donors will continue to be sent by email. 
  • If a patient wishes to write to their donor, please advise the patient to give it to their transplant coordinator, who will email it onto the Donor Follow Up team, or the patient can email it directly using  If a patient wishes to send a handmade item, then please send to Donor Follow Up, 2 Heathgate Place, 75-87 Agincourt Road London NW3 2NU. 
  • We are unable to send on gifts. 
  • Not all International Registries allow correspondence, please email Donor Follow Up  using if you would like to check the rules.  


  • Travel disruption continues but we are working hard to keep everything on track. We have seen a reduction in the number of available flights and that may impact timings of specific import provisions. We’ll continue to keep in regular contact with those affected along the way. 
  • International couriers are delivering products directly to UK transplant centres to ensure cells are as fresh as possible.   
  • We are following any changes in protocol for collection or delivery of cells at individual collection centres and transplant centres.  
  • International stem cell couriers importing and exporting cells are exempt from quarantine rules and will be provided with a letter stating this prior to travel, which can be shown to border agents on arrival in the UK.
