titleWhy is the number of search results so different than in the legacy system?

In the legacy system when running a standard donor search, all returned donors have values for A, B and DRB1. This is different when running a search in the new system. There all donors need to have typing at A, B and at least one other locus (which may or may not be DRB1). This means that donors are returned in the new system that do not have typing at DRB1. This typically explains the majority of the difference in number of search results as mentioned in the search summary. 


Although in some cases these donors with typing at A, B and C or DQB1 may prove useful, in most cases they are not. We therefore apply a default filter to all search results. 

You can see all donors by unchecking the default filter. 


Because the filter is applied by default, you may notice a difference in the total number of donors/cords as described in the search summary text versus the number displayed just above the list of potential matches. For example in the example below, there are 33 donors in the full search results. 3 donors did not have typing at DRB1 and have therefore been filtered out in the donor search results shown. 

You can see that a filter has been applied by the "1" icon on the "All filters" button.

titleWhat is asynchronous matching?

Asynchronous matching is a process of running searches in parallel. It allows you to enter a patient and start the search run, and proceed with other activities within the application like entering another patient or reviewing another match list while the search runs in the background. You do not have to wait for the current search to finish before proceeding with other activities.
