My clients come to me with stacks of labs sometimes. Other times they come with none at all, just a long list of symptoms they've been dismissed for, and a deep suspicion that something is off. Both situations can be a problem. Running every possible panel because you saw something on social media wastes money and can send you chasing your tail. But going years without identifying a real, correctable deficiency? That's the one that breaks my heart, because I see it all the time.
