SDN Members don't see this ad. (About Ads) Before med school, I shadowed a family doctor. My shadowing experience has lead me to wonder what the incentive or disincentive is for a physician to order tests. For example, a patient would come in with an unknown skin problem. He would give the patient advice and sometimes a perscription without any testing to determine the microbe that is causing the problem. I also noticed this with blood work also. So my questions is: do family medicine doctors get compensated for taking blood samples or other sample to be submitted for lab work? Thanks.
