Why are some drugs not included on your report? If a drug is not included on your report, does that mean it will work well for me?

If a medication is not included in our report, it is because no gene variants have yet been identified that are known to affect individual responses to that particular drug. In some cases, there may only be a single study that has shown a relationship between a gene and response to a drug, but the evidence is not yet strong enough to be relied upon and therefore we do not include it in our report.
