According to healthcare providers and experts in this space, doing blood tests annually (once a year) can essentially help you track your overall physical health and wellbeing. The results ensure that you have relevant information about changes (good or bad) in your body, this gives you the knowledge you need to make measured and informed decisions about your health. Thus, in case an illness is detected, you’re able to either get treatment or begin to make lifestyle changes early on—this information can save a life in the case of diseases like cancer where early detection can make a difference between life and death.
