Hi and welcome to HCM.
Nothing can be done quickly in medicine. i am not sure why is this test important for employment but ok. you should treate it primarly by changing lifestyle and dietary habits .eat healthier food and lose weight,avoid alcohol ,stress
. If this is not helpful,you ll need certain medications such as statines. Also,these findings are hardly predictable so it may periodically increase and decrease. Wish you good health. Regards
