Do you go to a doctor to prescribe blood work for you? I am interested in doing bloodwork as part of a wellness check to check for deficiencies etc but am unsure about how to approach this.
If you live in the USA you should be able to order online and then go in person to like a labcorp or whatever. If you ever got a drug test for a job, thats the sort of place that usually does it. I think some states you may need a referral but most you do not. For a hormone related test covering testosterone and other factors it is going to cost >100 dollars.
