What Sets Us Apart at WellMax

There are two fundamental approaches to health care:

Optimal Individualized

Medicine at WellMax

At WellMax we seek out the best, not the cheapest screening and treatments, to maximize wellness. It turns out that using the best is not expensive or time-consuming. We do not compromise when it comes to your health.

Population-based

Cost-effective Medicine

Cost effective medicine requires saving money so second tier screening tests may be OK to detect more disease in the big population. This is a good strategy for minimizing cost per patient for the federal government or an HMO but it is not appropriate for you.

Even at esteemed places like Mayo Clinic, Scripps, or UCLA, their executive physical programs apply population-based medicine. See below for examples of…

Differences Between Mayo and WellMax

Early Detection Screening Tests Wellmax Optimized Approach Cost-Effective Approach
Screen for lung cancer
and other lung disease
  • Rapid spiral lung CT scan, single breath-hold.
  • Far higher resolution than chest X-ray and early cancer detection.
  • In 1999 the landmark ELCAP study compared chest Xray and CT in the same patients, and found 27 cancers by CT, but only four of these were found by chest Xray.  It’s the small curable tumors for which Early Detection saves lives!

  • Chest X-ray: Unchanged for 50+ years. Saves money but misses most lung cancer detected by CT.
Cholesterol and other lab tests that measure heart disease risk
  • Extensive testing of over 20 measures of heart risk factors including:
    • LDL particle count in nmol/L, not just weight in mg/dL
    • LDL size, small dense or large buoyant?
    • Lp(a), a crucial independent and modifiable risk factor
    • Homocysteine, a measure of methylation impairment
    • C Reactive Protein, a measure of inflammation
    • Lipoprotein-associated phospholipase A2 (Lp-PLA2) activity 
    • Fasting insulin and C peptide
  • HDL, LDL cholesterol
Menopause in women, Andropause in men, and other age-related changes in hormones
  • Estradiol (LC/MS/MS)
  • Total and free testosterone
  • DHEA-S
  • Cortisol
  • DHT if needed for men with elevated PSA or enlarged prostates

Changes in women at menopause with new onset low estrogen is now known to be associated with osteoporosis heart disease cognitive function and even unhealthy skin.

Some men discover new onset low levels of testosterone. Increased testosterone will increase muscle mass, bone density, libido, and sexual function

  • Hormones are not included or tested routinely.  They claim they can do “if medically necessary.” 
Screen For Plaque In The Coronary Arteries
  • Coronary CT Angiogram directly visualizes calcified and soft plaque; detects narrowing in the arteries.
  • Available is optional Cleerly, an artificial intelligence analysis to help identify and define atherosclerosis earlier.
  • Exercise stress test and ECG: Unchanged for 50+ years.
  • Sensitivity 68%, so it misses 1/3 of patients with coronary disease
  • No coronary calcium score or CTA or any visualization of coronary arteries.
Skin Screening For Melanoma And High-Risk Cancer Moles
  • IntelliStudio automated photography system with Artificial Intelligence and Canfield D200 dermatoscope catalogs moles.
  • High-resolution, very close photos of each mole to provide advanced, early diagnosis of skin cancer.
  • A digital record is provided for later comparison.
  • Dermatologist looks over your skin, and makes a note about what was seen: Unchanged for 50+ years.
