3 and 4 mismatch searches have now been implemented for Cord searches. Here are some things you need to know: 

• In order to minimise unnecessary use of resource-intensive 3 and 4 mismatch cord searches, you first need to have finished
  • a 2 mismatch search before you can start a 3 mismatch search
  • a 3 mismatch search before you can start a 4 mismatch search
• No probabilities are calculated. This is similar to the legacy system. Sorting is performed within the match class (i.e. 5/8. 4/8) based on the TNC count or CD34 count (depending on what you have selected. TNC count is the default)
• It is advisable to use filters as the number of results can be great. You can for example filter on the minimum TNC, minimum CD34 or by certain registries or mismatch locations.
