 [ Symptoms ] pharmacogenetics testing does it work what negative aspects should a person consider how prevalent is it is use will insurance companies base what they will authorize based on these results [ Disease ] insurance companies may cover certain types of genetic testing but there seems to be no consistency in how or which tests are covered the only way to know is to contact your health plan directly to find out to answer your question yes it does work but they are limited by the amount genes that have been sequenced and workd on so far negative aspects are yet to be fully understood but as far as health goes the advantages are pretty fantastic the ramifications of having a health provider screen you based on your genetic disposition is a scary thought for a lot of folks it is use is increasing especially in the light of president obama is recent speech including it the president called pharmcogenetics precision medicine  video link and called for a huge amount of money to be dedicated towards development and research in this field it is use is surely going to expand it makes sense saves time money and whole lot of effort you can call your insurance company and find out if it is something they will cover but it is relatively new this subject is something that i personally find fascinating and i found a lot of good information about pharmaco genetic testing it is only going to be growing and i kinda get excited thinking about how many people this new technology is going to help i myself have struggled to find the right meds for me but with genetic screening and testing i do not have to worry about that as much bottom line it is something you should research some more but it could be very worth it hope that helped jim
