So no, routine blood tests don't test for cancer. And even if they could, they probably shouldn't (unless they are very, very good tests). If a person has other information - symptoms, family history,etc, this changes the base rate, and changes the interpretation of the test.
Quest Bowhunting is the brand of compound bows that are made by the G5 Outdoors Company. You will find the bows either under the brand name of Quest or else the parent company will be acknowledged in the name and the bow will be referred to as a G5 Quest compound bow.
Find the maker of the compound bow and email the picture or serial number to the company, asking for a confirmation on the bow's year of production. Lists of compound bow makers are found at websites such as Hunter's Friend. Check a Bear bow (the name of the maker) for a series of different criteria to determine its age.
