Is this you?
If this sounds like you, keep reading.
You track sleep, HRV or resting heart rate and want a doctor who takes the data seriously.
You have asked about ApoB, homocysteine or Lp(a) by name and been told a lipid panel is enough.
You have been told your labs are normal while you feel anything but.
You follow the longevity conversation closely and want it applied to you, by a physician.
You are willing to invest in testing and care your insurance does not cover.

What we measure
The physical stops where the trajectory starts.
A standard physical answers one question well: is something wrong right now? These are the additional measures that answer the one you are actually asking, and the lever attached to each.
| Domain | A standard physical | What we add | Why it matters |
|---|---|---|---|
| Cardiovascular | Total, LDL, HDL cholesterol | ApoB, Lp(a), hs-CRP, homocysteine | Particle count and inflammation predict events better than cholesterol content alone |
| Metabolic | Fasting glucose | Fasting insulin, uric acid, CGM where indicated | Insulin resistance is visible years before glucose moves |
| Body | Weight, BMI | DEXA body composition, grip strength | Muscle mass and visceral fat drive outcomes; BMI hides both |
| Fitness | Not measured | VO2 max, resting heart rate, HRV trend | Among the strongest predictors of mortality medicine has |
| Hormones | Rarely, unless symptomatic | Full panel with free fractions, read against symptoms | Energy, cognition, body composition and sleep all sit here |

Questions we hear
Straight answers, before the first visit.
Largely no. Insurance pays to treat disease, not to prevent it. We are direct about cost before anyone commits, and the first consultation is where that conversation happens.
The physical screens for disease already present against population ranges. We measure the markers that predict the next twenty years, read them together, and re-measure every quarter. It complements your primary care; it does not replace it.
Typically within two weeks for the first visit. The full baseline and the read-through follow over the next two to four weeks.
TPE removes plasma and the inflammatory factors circulating in it. The evidence for longevity uses is early and we say so. It is offered to selected patients whose numbers make the case, never as a first step.
Telehealth Available
You do not have to live near Philadelphia to be our patient.
Hormone and metabolic care is mostly conversation, laboratory work and adjustment over time. All three travel well. Patients across Pennsylvania do this with us on video, with their blood drawn close to home.
Where this is available. Dr. Christian is licensed in Pennsylvania, so telehealth is available to patients who are in Pennsylvania at the time of the visit. If you are elsewhere, the office in the Philadelphia area sees patients in person.
- Step 1
A consult on video
Your history, your symptoms and what you want to change, with the physician rather than an intake form.
- Step 2
Labs drawn near you
We send the order to a draw site close to home. You do not travel for a blood test.
- Step 3
Results read together
We go through the panel on screen, and you leave with the plan written down rather than a portal message.
- Step 4
Follow-up on video
Re-testing and adjustments happen on the same schedule they would in the office.
