This is a new guideline from NICE published in Jul 2024.
It advises that CYP2C19 genotype testing can be carried out on certain people to see if they will respond to clopidogrel.
Who can this be used for?
People who have just had an ischaemic stroke or TIA. It is anticipated that at first this technology won’t be available for many people, so it will be targeted at those most likely to benefit.
