Free guides — the same ones I wish someone had handed me.
When I was the patient, no one was investigating why. These are the root-cause guides I built so you don’t have to start where I did — dismissed, mislabeled, and still sick. No fluff. No upsells. Real medicine.
“Several years ago, conventional medicine almost gave up on me. Multiple MRI lesions, every test ‘normal,’ and no one asking why. An IGeneX test finally found it. That’s why I wrote these — and why I’ll never give up on you.”

The Lyme Patient’s Guide to Real Testing
Six months of “normal” labs nearly cost me everything. Then an IGeneX test found what standard serology missed — the same test most clinics still don’t order. This is the guide I needed back then: exactly what to test, why conventional panels miss active infection, and how to read results most providers misinterpret.
- Why standard two-tier serology produces false negatives
- The tickborne panels that actually detect active infection & co-infections
- How to interpret results when your doctor says “you’re fine”
- The integrated path forward — conventional and functional
Root-cause answers for the conditions other clinics miss or mismanage.
Every guide is written by Dr. Osgood and grounded in the same testing and protocols we use in clinic. Pick the one that matches what you’re fighting.
