Evidence-based recommendations on CYP2C19 genotype testing to guide clopidogrel use after ischaemic stroke or transient ischaemic attack.

NICE is working with NHS England, who will initially deliver a national pilot to produce an implementation guide for providers and information to support future commissioning decisions. The pilot will run from October 2024 to April 2025. We will notify stakeholders when supporting information on implementation is available.

Last reviewed: 31 July 2024

Next review: This guidance will be reviewed if there is new evidence that is likely to change the recommendations.

Guidance development process

How we develop NICE diagnostics guidance

 

Your responsibility

This guidance represents the view of NICE, arrived at after careful consideration of the evidence available. When exercising their judgement, healthcare professionals are expected to take this guidance fully into account, and specifically any special arrangements relating to the introduction of new interventional procedures. The guidance does not override the individual responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient, in consultation with the patient and/or guardian or carer.

All problems (adverse events) related to a medicine or medical device used for treatment or in a procedure should be reported to the Medicines and Healthcare products Regulatory Agency using the Yellow Card Scheme.

Commissioners and/or providers have a responsibility to implement the guidance, in their local context, in light of their duties to have due regard to the need to eliminate unlawful discrimination, advance equality of opportunity, and foster good relations. Nothing in this guidance should be interpreted in a way that would be inconsistent with compliance with those duties. Providers should ensure that governance structures are in place to review, authorise and monitor the introduction of new devices and procedures.

Commissioners and providers have a responsibility to promote an environmentally sustainable health and care system and should assess and reduce the environmental impact of implementing NICE recommendations wherever possible.
