Testing is individualized. Not every patient needs every test, and recommendations depend on your health history, symptoms, risk factors, and goals.

Depending on your needs, laboratory evaluation may include:

Metabolic Health & Blood Sugar

Standard glucose testing does not always tell the full story.

We may consider:

• Fasting glucose, hemoglobin A1c, fasting insulin

• Continuous glucose monitoring

• Homocysteine level

• Uric acid

• Additional metabolic markers when clinically appropriate

These results can help provide a more detailed picture of glucose regulation and metabolic health.

Cardiovascular & Lipid Risk

For some individuals, a standard cholesterol panel provides only part of the picture.

Evaluation may include:

• Total cholesterol, fractionated LDL, HDL cholesterol, and triglycerides

• Apolipoprotein B (ApoB)

• Lipoprotein(a), or Lp(a)

• High-sensitivity C-reactive protein (hs-CRP)

These markers can help us better understand cardiovascular and metabolic risk and determine when further evaluation through your primary care physician or cardiologist may be appropriate.

Nutritional & Micronutrient Status

Nutrient needs differ from person to person, and standard laboratory testing may not always include nutrients relevant to energy, cognition, mood, or healthy aging.

Testing may include:

• Vitamin B12

• Vitamin B6

• Folate

• Methylmalonic acid

• Homocysteine

• Vitamin D

• Iron, ferritin, and iron saturation

• Magnesium

• Zinc and copper when indicated

• Nutritional lithium

• Omega-3 fatty acid status

• Foot sensitivity testing

• Additional nutritional markers based on diet, symptoms, medications, and clinical history

We use laboratory findings to identify clinically meaningful deficiencies or imbalances and recommend targeted interventions when appropriate.

Thyroid & Hormonal Health

Hormonal changes can influence energy, metabolism, sleep, cognition, mood, and overall well-being.

Depending on your symptoms and history, evaluation may include:

• TSH

• Free T4

• Free T3 and reverse T3 when appropriate

• Thyroid antibodies when appropriate

• Selected reproductive hormones

• Additional hormone testing when clinically indicated

Hormonal testing is interpreted in the context of age, symptoms, medications, menstrual status, and other relevant health factors.

Genetics & Specialized Testing

Some patients may benefit from more individualized testing beyond standard bloodwork.

Depending on your goals, we may discuss:

• Nutrigenomic testing

• Pharmacogenomic testing

• APOE and MTHFR testing

• Gut health testing

• Selected functional or specialty laboratory assessments

Specialized testing is recommended selectively when it is likely to provide useful information or meaningfully influence care.

Laboratory testing can provide valuable information about metabolic health, cardiovascular risk, nutritional status, hormones, inflammation, and other factors that influence how you feel today and your health over time.

But laboratory results are most useful when they are interpreted in context.

At Marathon Wellness, our Laboratory Consultation Visits combine your laboratory findings with your medical history, symptoms, lifestyle, family history, medications, and health goals. Dr. Rachel Kermen reviews the bigger picture and helps you understand which findings are meaningful, which may require additional evaluation, and where there may be opportunities to improve your health.

These visits are ideal for individuals who want a physician-led, integrative interpretation of their laboratory data without initially enrolling in a comprehensive membership program.
