Preventative Testing
Don't Wait to Get Sick. Preventative Testing With Dr. Dubroff.
Integrative lab testing that looks for what's changing — not just what's already broken. Catch imbalances early, act before symptoms become serious, and understand your health with a level of detail standard medicine rarely offers.
Most doctors order a standard panel, compare your results to population-wide reference ranges, and tell you everything looks normal. But 'normal' in conventional medicine means you haven't crossed into diagnosable disease — not that your body is functioning optimally. Dr. Dubroff uses integrative testing reference ranges and a broader panel of markers specifically chosen to catch problems while there's still meaningful room to intervene.
Conventional Lab Testing Is Designed to Find Disease. Not to Keep You From Getting It.
Standard reference ranges used in conventional medicine are derived from large population averages — including a significant portion of people who are not in optimal health. When your results fall within those ranges, your doctor tells you everything is fine. But 'fine' by that standard simply means you haven't reached the threshold for a clinical diagnosis.
The problem is that the most serious conditions — heart disease, hormonal decline, autoimmune disease, cancer — don't appear suddenly. They develop slowly, over years, through gradual changes that standard testing is not designed to catch early. By the time a conventional panel flags something, the window for easy intervention has often already passed.
Dr. Dubroff's approach is different. He uses a broader set of markers, interpreted through integrative reference ranges, to identify meaningful changes before they become serious problems. The goal isn't to find disease — it's to make sure you never get there.

Four Categories. One Comprehensive Picture.
Dr. Dubroff runs integrative testing across four key areas — each chosen because early detection in these categories is where intervention has the most meaningful impact on long-term health outcomes.
Hormonal & Sub-Clinical Testing
Hormonal decline is gradual, and conventional medicine often doesn't flag it until levels have dropped significantly below optimal. Dr. Dubroff tests across a full hormonal panel and interprets results through integrative ranges — identifying sub-clinical imbalances that affect energy, mood, body composition, sexual health, and quality of life.
Estrogen (Estradiol and Estriol) — levels and balance, relevant to both men and women
Progesterone — balance relative to estrogen, mood and sleep implications
Testosterone — total and free, relevant to energy, muscle mass, and drive in both sexes
DHEA and cortisol — adrenal function and stress hormone balance
Thyroid panel — TSH, Free T3, Free T4, and reverse T3 where indicated
Growth hormone markers — IGF-1 as a proxy for growth hormone status
For women, hormonal changes associated with perimenopause and menopause — particularly declining estrogen levels — can significantly affect quality of life in ways that are often undertreated or dismissed by conventional medicine. Dr. Dubroff takes a careful, individualized approach to hormonal support, using bio-identical hormones where appropriate.
All hormonal therapy recommendations are based on a thorough evaluation of each patient's individual health picture, history, and goals. These therapies are not appropriate for every patient and are always discussed in full detail before any recommendation is made.
Digestive & Gut Health
Standard cholesterol panels measure total cholesterol, LDL, HDL, and triglycerides. These are useful but incomplete. The actual disease process that leads to heart attacks and strokes is atherosclerosis — the buildup of plaque in arterial walls — and cholesterol numbers alone are a limited predictor of whether that process is occurring.
Dr. Dubroff's advanced cardiovascular panel goes further, looking at markers that more directly reflect cardiovascular risk and arterial health.
Advanced lipid panel — particle size and number, which are more predictive of cardiovascular risk than standard LDL alone
Coronary calcium score — an imaging test that directly measures calcified plaque in the coronary arteries, providing a more direct assessment of cardiovascular risk than blood markers alone
Carotid intima-media thickness (CIMT) — an ultrasound-based assessment of the carotid arteries in the neck that can indicate risk of future cardiovascular events including stroke
Inflammatory markers — including high-sensitivity CRP, which reflects systemic inflammation closely tied to cardiovascular risk
An important note on dietary fat and cardiovascular risk: emerging and ongoing research has continued to refine our understanding of the relationship between dietary choices and cardiovascular outcomes.
The quality and type of fat consumed — particularly saturated fat intake — appears to be a meaningful factor in atherosclerotic progression, distinct from cholesterol numbers alone. Dr. Dubroff discusses this in detail with patients whose cardiovascular risk profile warrants it.
Autoimmune Early Detection
Autoimmune conditions — in which the immune system mistakenly targets the body's own tissues — are being diagnosed at a significant and increasing rate. Many of these conditions develop gradually over years before reaching the threshold of a clinical diagnosis, during which time targeted lifestyle and dietary interventions can meaningfully alter their progression.
Dr. Dubroff runs a core autoimmune panel on patients where indicated, with the goal of identifying early immune activity before it becomes a diagnosed condition.
• ANA (Antinuclear Antibody) — a broad screening marker for autoimmune activity
• Anti-CCP (Anti-Cyclic Citrullinated Peptide) — associated with rheumatoid arthritis and other autoimmune conditions
• CRP (C-Reactive Protein) — an inflammation marker used to assess whether detected autoimmune markers reflect currently active inflammation
The relationship between these markers matters: a positive ANA or anti-CCP result alongside a normal CRP suggests the immune activity may not yet be actively inflammatory — which is precisely the window in which dietary and lifestyle interventions are most impactful. Dr. Dubroff uses these findings to guide personalized recommendations on nutrition and lifestyle factors that support immune regulation.
Cellular Health Markers
Two markers that are not part of standard panels can provide meaningful early signals that something in the body is under unusual stress or experiencing breakdown — even before symptoms are present.
Creatine Kinase (CK) — elevated levels can indicate that muscle or other tissue is under stress or experiencing breakdown. Useful as a broad signal of physiological strain.
Lactate Dehydrogenase (LDH) — another marker of cellular breakdown, found in multiple tissue types.
Elevated LDH can reflect a range of conditions and is used as part of a broader picture, not in isolation.
Neither of these markers is diagnostic on its own — but as part of a comprehensive panel, they contribute to a more complete picture of how the body is functioning at a cellular level.
The Difference Between 'Not Sick' and 'Actually Healthy.'
Integrative testing uses the same laboratory infrastructure as conventional medicine — the same blood draws, the same accredited labs. What's different is how the results are interpreted.
Conventional reference ranges are wide by design — built to catch clear pathology across a broad population. Integrative reference ranges are tighter, derived from research into what optimal physiological function actually looks like. This means Dr. Dubroff can identify values that are technically within the conventional 'normal' range but are meaningfully below — or above — where they should be for a patient to feel and function their best.
This is particularly significant for hormonal markers, inflammatory indicators, and cardiovascular risk factors — areas where small, gradual changes accumulate over time and are routinely missed until they've progressed significantly.
What 'sub-clinical' means and why it matters:
A sub-clinical finding is one that falls in the gray zone between optimal and diagnosable disease. Conventional medicine often doesn't act on sub-clinical findings because they don't meet the threshold for a diagnosis. Integrative medicine treats this zone as exactly the right time to intervene — through nutrition, lifestyle modification, targeted supplementation, or hormonal support — before a clinical problem develops.
What the Process Looks Like
Step 1 — Free Consultation
Dr. Dubroff talks with you about your health history, current symptoms, family history, and goals. He determines which panels are most relevant for your situation and explains what each test is looking for and why.
Step 2 — Testing & Review at Your Home
Lab orders are placed and testing is coordinated. Once results are available, Dr. Dubroff reviews them with you in detail — not just flagging out-of-range values, but explaining what the full picture means and where he sees areas worth addressing. Your first full appointment is two hours, with a free bonus hour available for new patients within the first week.
Step 3 — A Plan Based on What's Actually Found
Testing without a follow-up plan isn't medicine — it's paperwork. Every finding is connected to a specific recommendation, whether that's a dietary change, a targeted supplement, a hormonal support protocol, or simply monitoring a marker over time. Dr. Dubroff builds an action plan around your results, not a generic wellness checklist.

A note on insurance and lab testing:
Naturopathic doctor consultations are not covered by insurance in California. However, many standard diagnostic laboratory tests — including several of the panels Dr. Dubroff orders — may be eligible for insurance billing depending on your plan and coverage. Dr. Dubroff's team can discuss your specific situation during your consultation to help you understand what may and may not apply to your coverage.
'Your Labs Look Normal.' Doesn't Mean You're at Your Best.
Sub-clinical findings — values that fall in the gray zone between optimal and disease — are where integrative medicine does its most important work. Conventional medicine often doesn't act on sub-clinical findings because there's no diagnosis to attach to them. But this is precisely when lifestyle and therapeutic interventions are most effective.
For hormones in particular, sub-clinical decline is extremely common as patients age — and is often responsible for symptoms that patients are told are simply 'part of getting older.' Fatigue. Weight changes. Mood shifts. Reduced drive. Disrupted sleep. These are not inevitable. They are frequently the result of gradual hormonal and metabolic changes that, when identified early, are highly addressable.
"I don't want to wait until a patient is sick to help them. I want to catch the changes that lead to sickness — and act on them while we still have options."
— Dr. Joseph Dubroff, N.D.
