This skill translates common blood test results into plain language and helps formulate informed questions for a physician. It does not diagnose conditions or recommend treatments. Lab interpretation is always context-dependent — age, sex, medications, and symptoms matter. Bring all questions to a qualified healthcare provider.
The CBC measures red blood cells (RBCs), white blood cells (WBCs), and platelets. Key markers: hemoglobin (oxygen-carrying capacity; low suggests anemia), hematocrit (percentage of blood that is RBCs), WBC count (immune activity; high can indicate infection or inflammation), and platelets (clotting). A single out-of-range value in isolation rarely means much — trends and clinical context matter.
The CMP screens organ function. Liver markers: ALT and AST (elevated with liver stress, heavy alcohol, or intense exercise); ALP (bile ducts and bone). Kidney markers: creatinine and BUN (waste clearance); eGFR (estimated kidney filtration rate). Electrolytes: sodium, potassium, chloride, bicarbonate. Glucose (fasting): normal is 70–99 mg/dL; 100–125 is pre-diabetic range. Calcium: relevant for bone and nerve function.
Measures cardiovascular risk markers. Total cholesterol alone is a poor predictor. Focus on: LDL (low-density lipoprotein — the primary target; optimal is generally under 100 mg/dL for most adults, lower for high-risk individuals), HDL (high-density lipoprotein — higher is better; under 40 mg/dL is a risk factor), and triglycerides (under 150 mg/dL is normal; high levels correlate with poor metabolic health). Ask the doctor about ApoB if cardiovascular risk is a concern.
TSH (thyroid-stimulating hormone) is the standard thyroid screen; abnormal values prompt follow-up with free T4 and T3. Testosterone (total and free) is relevant for symptoms of fatigue, low libido, or body composition changes in both men and women. HbA1c reflects average blood glucose over roughly 3 months and is the standard diabetes screen. Vitamin D (25-OH) is frequently low; optimal range is debated but most clinicians target 30–60 ng/mL.
Useful questions: What is the trend versus my previous results? Which out-of-range values require action now versus monitoring? Are any medications or supplements affecting these results? What lifestyle changes would move the most important markers? When should I retest?
Reference ranges are statistical, not absolute — they represent the middle 95% of a tested population, which includes undiagnosed sick people. Optimal ranges for longevity sometimes differ from standard lab reference ranges. Never self-diagnose from a single panel. Use results as a starting point for a productive conversation with a doctor.
Use when someone starts lifting, hits a strength or hypertrophy plateau, restructures a lifting program, or wants to build strength or muscle — designing a progressive resistance program with splits, compound movement patterns, sets/reps, progressive overload, and deloads from barbells and dumbbells. General fitness guidance, not medical advice. Owns resistance/strength training only. Do NOT use to program high-intensity interval conditioning or circuits (use fitness-program), a steady-state aerobic-base or Zone 2 block (use zone-2-cardio-plan), or a mobility/flexibility routine (use mobility-routine).
Use when someone asks to build a steady-state cardio plan, train an aerobic base or Zone 2, structure easy or endurance weekly cardio, train by heart-rate zones, or improve resting heart rate, VO2, or endurance. Builds a heart-rate-zone aerobic training block with session structure, modality choice, and progression. General fitness guidance, not medical advice. Do NOT use to design a strength or lifting program (use Strength Training Plan), high-intensity interval conditioning, HIIT, or circuits (use Conditioning & HIIT Program), or a mobility/flexibility routine (use Mobility Routine).
Designs prehab and mobility work to reduce injury risk for shoulders, knees, lower back, and hips. Use when starting a training program or addressing chronic tightness. General movement guidance; not medical advice; consult a physio for existing injuries.
Assembles an evidence-informed weekly longevity routine covering sleep, zone 2 cardio, strength training, and dietary patterns. Use when building or auditing a long-term health practice. General wellness guidance; not medical advice.
Builds a daily mobility and flexibility routine for desk workers targeting hips, thoracic spine, shoulders, and ankles. Use when addressing stiffness, poor posture, or building a movement practice. General guidance; not medical advice.
Helps users build a sustainable nutrition plan centered on protein targets, whole foods, and adherence strategies. Use when planning meals, adjusting macros, or building lasting dietary habits. Not medical advice.
