We’re Raising the Bar on Biomarker Testing — 4x More Than a Typical Doctor’s Visit

At Keyspan, we don’t just skim the surface — we go deep. While most standard checkups include 10–15 basic markers, we’ve now expanded our panel to include over 60+ critical biomarkers that reveal the full story of your health.

Why? Because real answers come from smarter, more targeted testing and more detailed action plans.

Starting today, we’re spotlighting a broader, more advanced set of must-know markers for both men and women — including a full hormone profile, advanced kidney function, liver health, immune resilience, and inflammation markers.

This is a game-changer for anyone serious about understanding their body, preventing disease, and optimizing performance.

🔬 Full Thyroid Panel (T3, T4, TSH, and TPO Antibodies)

Most standard labs check only TSH — and maybe free T4 if you’re lucky. But that’s just scratching the surface.

We now include:

T3 Uptake and Free Thyroxine Index (FTI): to assess thyroid hormone availability
TPO Antibodies: to detect autoimmune thyroid disease like Hashimoto’s

Why it matters: Many people with fatigue, brain fog, and stubborn weight gain are told their thyroid is “normal”—but functional testing often uncovers suboptimal conversion or hidden autoimmunity before a diagnosis is ever made.

🧬 SHBG (Sex Hormone-Binding Globulin)

Think of SHBG as your hormone traffic controller — it binds to testosterone and estrogen, deciding what gets delivered and what stays inactive.

Too high? You may have low free testosterone or estrogen, leading to fatigue, mood changes, or low libido.
Too low? You could have excess circulating hormones, which may drive acne, estrogen dominance, or irritability.

Our expanded panel now includes SHBG for both men and women, giving us a more complete picture of your hormonal bioavailability.

🧔 Free Testosterone (Male and Female)

We now stratify free testosterone by age and sex (e.g., males under 50 vs. over 50) to provide more accurate context. This hormone affects:

Energy and drive
Muscle retention
Cognitive sharpness
Libido
Motivation

Low free T can exist even when total T looks fine — and we now make sure you know the difference.

♀ Estradiol – Yes, for Men and Women

We’ve expanded estradiol testing across:

Pre-menopausal women
Post-menopausal women
Men

Estrogen plays a huge role in mood, bone health, metabolism, and cardiovascular protection. Whether you’re managing menopause symptoms or optimizing male hormonal balance, we now give you the detail to act with precision.

🧪 Kidney & Liver Function — New Markers That Matter

Our new panel includes:

eGFR, Creatinine, BUN, BUN/Creatinine Ratio – to assess kidney filtration and hydration status
Bilirubin, ALT, AST, Alkaline Phosphatase, Globulin, VLDL – to evaluate liver performance and detox capacity

Why this matters: Poor kidney or liver function often starts silently and can impact energy, inflammation, and how well your body processes toxins, hormones, and medications. Early detection = longer healthspan.

🛡️ Immune Function & Inflammation

We’ve added a complete immune differential panel, including:

Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils, Immature Grans

Plus, we still include:

Cardiac CRP and Homocysteine to assess silent inflammation, vascular risk, and oxidative stress

This helps us identify immune dysfunction, chronic stress response, and hidden drivers of fatigue or autoimmunity.

🧠 What Functional Testing Tells Us That Standard Testing Doesn’t

We don’t ask: “Is this in the normal range?”

We ask: “Is this optimal — for you?”

Functional lab testing connects the dots between symptoms and systems. Instead of looking at one biomarker at a time, we examine how patterns emerge across:

Hormones
Detox function
Metabolism
Immune health
Inflammation
Nutrient status

This helps us map out the real reasons behind:

Fatigue
Mood swings
Weight gain or plateaus
Poor stress tolerance
Low libido
Brain fog
Cycle irregularities or ED
Sleep issues
Detox overload
