Diagnostic Testing & Blood Panels in Miami

Why We Test Before We Treat

At Rewind Anti-Aging, we don't prescribe based on symptoms alone. Symptoms can overlap across conditions — fatigue can be caused by low testosterone, hypothyroidism, vitamin D deficiency, insulin resistance, or cortisol dysfunction. Without comprehensive bloodwork, treatment is guesswork.

Our diagnostic approach gives us a complete metabolic and hormonal picture so every treatment decision is informed by data, not assumptions.

Comprehensive Hormone & Metabolic Blood Panel

Our standard panel goes far beyond what you'd get at a typical doctor's visit. We test the full spectrum of hormones, metabolic markers, and health indicators:

Hormone Panel

• Total and Free Testosterone — the most critical marker for men; also important for women's energy, libido, and body composition
• Estradiol (E2) — primary estrogen; essential for women's health and must be monitored in men on testosterone therapy (can convert via aromatization)
• Progesterone — sleep, anxiety, endometrial protection in women
• DHEA-S — adrenal precursor hormone; reflects adrenal function and stress response
• SHBG (Sex Hormone Binding Globulin) — determines how much of your total testosterone is actually available for use (free vs. bound)
• Cortisol — stress hormone; chronically elevated cortisol suppresses testosterone, thyroid, and immune function

Thyroid Panel

• TSH — pituitary signal to the thyroid; often the only thyroid test run by other providers, but insufficient alone
• Free T3 — the active thyroid hormone your cells actually use for metabolism
• Free T4 — the storage form of thyroid hormone that converts to T3

Many patients with "normal" TSH have suboptimal free T3 levels, leading to symptoms of hypothyroidism (fatigue, weight gain, brain fog, cold intolerance) that go undiagnosed. We test the full thyroid panel to catch what others miss.

Metabolic & General Health

• CBC (Complete Blood Count) — red and white blood cells, hemoglobin, hematocrit (important for monitoring testosterone therapy safety)
• CMP (Comprehensive Metabolic Panel) — liver function, kidney function, electrolytes, glucose
• Lipid Panel — total cholesterol, LDL, HDL, triglycerides
• Hemoglobin A1c — 3-month average blood sugar; screens for insulin resistance and diabetes
• Fasting Insulin — early indicator of metabolic dysfunction, often elevated years before blood sugar rises
• Vitamin D (25-OH) — chronically low in most adults; impacts immune function, mood, bone health, and testosterone production
• PSA (men) — prostate-specific antigen; baseline and monitoring marker for prostate health

Galleri Multi-Cancer Early Detection Test

The Galleri test represents a paradigm shift in cancer screening. Developed by GRAIL, this blood test can detect a shared cancer signal across more than 50 types of cancer — including many that have no standard screening test today (pancreatic, liver, ovarian, stomach, and others).

How It Works

Cancer cells shed fragments of their DNA into the bloodstream (cell-free DNA, or cfDNA). The Galleri test analyzes methylation patterns on this cfDNA — specific chemical modifications that differ between cancer and non-cancer cells. When a cancer signal is detected, the test also predicts where in the body the cancer originated, helping direct follow-up diagnostic workup.

Key Facts

• Detects 50+ cancer types with a single blood draw
• Many detected cancers have no other recommended screening (e.g., pancreatic, liver, ovarian)
• Less than 1% false positive rate — meaning a positive result is highly likely to be real
• Recommended for adults 50 and older or those with elevated risk factors
• Complements — does not replace — standard screenings (mammography, colonoscopy, etc.)
• Early detection saves lives: cancers caught at stage I/II have dramatically better survival rates than stage III/IV

TrueAge Epigenetic Diagnostic Test

Your chronological age is how many birthdays you've had. Your biological age is how old your cells actually are — and they're often different. TrueAge measures your biological age through epigenetic analysis, giving you a precise picture of how your body is aging at the molecular level.

What It Measures

TrueAge analyzes DNA methylation patterns — chemical markers on your DNA that change over time in response to aging, lifestyle, diet, exercise, stress, and environmental factors. These patterns have been validated as the most accurate biomarker of biological aging available today.

Why It Matters

• Baseline assessment — know your true biological age before starting any anti-aging program
• Treatment tracking — repeat testing after 6-12 months of treatment to objectively measure whether your interventions (HRT, lifestyle changes, peptides) are actually reversing biological aging
• Motivation — seeing your biological age decrease is a powerful motivator to maintain healthy habits
• Risk stratification — a biological age significantly higher than chronological age may indicate accelerated aging that warrants more aggressive intervention

Boston Heart Cardiovascular Testing

Standard lipid panels tell you your cholesterol numbers, but they don't tell the full story. Boston Heart advanced cardiovascular testing goes deeper to assess your true cardiovascular risk:

• LDL particle number and size (small dense LDL is more dangerous than large buoyant LDL)
• Lipoprotein(a) — a genetic cardiovascular risk factor that standard panels miss
• Inflammation markers (hs-CRP, Lp-PLA2)
• Metabolic markers affecting cardiovascular risk

This testing is particularly valuable for patients with a family history of heart disease, borderline cholesterol levels, or those wanting the most complete cardiovascular risk assessment available.

Microscopy & Pathogen Testing

For patients with unexplained symptoms — chronic fatigue, digestive issues, immune dysfunction, or recurrent infections — we offer specialized microscopy diagnostics that identify pathogens including parasites, bacteria, yeast, and fungi that may be contributing to your symptoms.

How Our Diagnostic Process Works

1. Consultation — discuss your symptoms, health history, and goals to determine which tests are appropriate
2. Blood draw — performed in our Wynwood clinic by trained phlebotomists. Most panels require a morning fasting draw
3. Lab processing — results typically available within 5-10 business days (Galleri and TrueAge may take 2-3 weeks)
4. Results review — we sit down with you to review every result in detail, explain what each marker means, and discuss what's optimal vs. just "normal"
5. Treatment plan — based on your complete diagnostic picture, we design a personalized protocol addressing every identified issue
