Is there a genetic test in uk that can tell if a person is a poor metabolizer with clopidogrel having two copies of each of the cyp2c19 gene.?

Phenotype is the big: issue, not genotype, because we each live with the complex results of both genotype combined with all our complex internal controls, beyond just any gene or sets of genes alone. Since clopidgrel is a platelet suppressing, clot-slowing agent, best check clotting with & without whatever trial dosage. The best of the clotting tests is TEG, study: Thromboelastography, commonly used in hospitals.
