Advanced Testing, Expertly Interpreted for Real Answers

We go beyond the basics with specialty testing that reveals what’s really going on—then translate complex results into clear, actionable insights to guide your personalized care plan.

Advanced Testing is Only Helpful if It’s Understood.

At Philadelphia Integrative Medicine, we go beyond ordering labs—we help you make sense of them. Our team expertly interprets advanced tests to uncover what’s driving your symptoms and how to treat it, step by step.

What Is Specialty Testing?

Specialty testing looks deeper than standard blood work. These labs assess function—not just disease—and often include:
  • Gut microbiome analysis (e.g. GI-MAP, Genova Diagnostics)

 

  • Hormone and adrenal testing (e.g. DUTCH, saliva, urine)

     

  • Mold, mycotoxin, or heavy metal exposure

     

  • Food sensitivity & immune response (e.g. IgG/IgA panels)

     

  • Nutrient absorption, mitochondrial function, oxidative stress

     

  • Autoimmune, Lyme, and stealth infections

     

  • Genetic panels (MTHFR, detox pathways)

     

  • These are powerful tools—but only when interpreted correctly.

How We Stand Out

Why PIM is Different

Collaborative Team Care

We meet as clinicians to review and refine treatment strategies.

Extensively Trained Providers

All team members are board-certified and integrative/functional medicine trained.

Expert Interpretation of Labs

Many order labs. Few know how to interpret them. We do it right.

Time to Listen

Sessions range from 60–90 minutes because real care takes time.

In short, I found the group … terrific. Comfortable. Caring. And knowledgeable. Far exceeding any medical group I have dealt with in years.

Philadelphia Integrative Medicine has been a lifesaver for me. When I first went, a year ago,, I felt like I was 85 and aging fast. Now I feel, if anything, younger than my actual 64, and getting better all the time. Three people this week told me they thought I was 55! PIM's comprehensive, detailed approach is based in extensive testing, so there's a whole lot less guesswork and a whole lot more success. I have seen both Dr. Tetlow and Dr. Patterson and am a huge fan of both. Cannot recommend highly enough. Pricey, but worth every penny if you can swing it.

I am a relatively new but, so far, a very satisfied PIM customer. After 10 months of looking for a health care provider who would listen to, collaborate with and communicate with me to treat ongoing GI issues, I found Amy Nutter (NP) and Jennifer Patterson (DO). Both women are smart, thorough, compassionate, and very responsive to the follow-up questions I ask between appointments. To a person, everyone with whom I have interacted in the office is exceptionally professional and kind. Thank you for being there, PIM!

I have pursued many avenues to get a resolution to my health issues - which included at times debilitating fatigue, headaches, and GI issues - and through comprehensive labwork and a holistic approach I not only have answers to the underlying causes, but am feeling better in the first time in ~4 years of trying to find an answer to my health issues thanks to the team at Philadelphia Integrative Medicine.

PIM is life changing. My wife was treated about five years ago to resolve some long standing issues no regular primary care doc nor specialists she saw could get to the bottom of. Years later I signed up and am receiving the same exceptional care and attention you would want from your Doctor. If all medical care could be done this way, our world would just be better. All members of PIM from Dr. Tetlow to her scribe give me (and gave my wife) the utmost care, compassion and competence. We recommend this practice to EVERYONE, including other practitioners as the model of what healthcare should be.

I can't say enough good things about Dr. Jennifer Patterson. She is extremely knowledgable, caring, and resourceful! I always leave feeling better than when I came in.

My Dr. is Dr. Patterson. My experience is that she is smart, thoughtful, thorough and engages me in my own health journey. Exactly what I want in a doctor. I enjoy consulting with her and respect and appreciate her advice and opinion.
