We’ll let you know whether you meet our criteria by your preferred contact method. If you don’t meet the criteria to be sent a DNA saliva sample kit, your questionnaire answers will still help us progress research. You will still have the opportunity to be contacted about future opportunities to be part of research if you have consented to this.

It’s important to note that not meeting our criteria doesn’t mean you don’t have ME/CFS. DecodeME uses narrow research criteria for scientific reasons, and we expect some people with ME/CFS to fall outside them.

Read the FAQ Why did I not meet the study criteria? for more information on why this is.
