Understanding Pediatric Lab Ranges

A clinically grounded approach to interpreting laboratory values across developmental stages

Why This Course Matters

Pediatric lab interpretation is one of the most common sources of uncertainty in practice. A “flagged” alkaline phosphatase that turns out to be normal growth. A borderline TSH in a preteen that raises questions of early thyroid dysfunction. A ferritin of 20 ng/mL that looks “normal” on the lab slip but may not be adequate for a school-aged child struggling with school performance.

Most labs report adult reference ranges — leaving clinicians to interpret pediatric values without the proper context. The result? Wasted time searching reference tables, unnecessary re-testing, missed deficiencies, or over-treatment.

This course was created to bridge that gap.

What You’ll Gain

In Understanding Pediatric Lab Ranges, you’ll learn how to confidently interpret pediatric results across developmental stages using an evidence-based framework. You’ll walk away with:

• Age-specific cutoffs for CBC, CMP, thyroid function, and key nutritional labs

• Clear guidance on when “abnormal” results are normal in children — and when they warrant action

• Nutritional lab interpretation tools, including:

  • Signs and symptoms of specific nutrient deficiencies in children

  • When to test for deficiencies such as iron, zinc, vitamin D, B12, folate, riboflavin, thiamine, magnesium, and more

  • The most evidence-based biomarkers to order (and functional tests when appropriate)

  • How to interpret results as normal, abnormal, suboptimal, or optimal

• Templates for lab ordering in common pediatric presentations (ADHD, picky eating, fatigue, lymphadenopathy, growth failure)

• Case-based examples to illustrate real-world application

• A 95+ page searchable Pediatric Lab Interpretation Guide, designed for daily use in clinical practice

The included 95+ page Pediatric Lab Interpretation Guide is designed for real-world clinical use. Organized by laboratory marker, it allows you to quickly look up the correct pediatric reference ranges, see what’s truly normal, and identify when a value requires further investigation. Whether you’re in the middle of a visit or reviewing charts after hours, the guide functions as a searchable, point-of-care reference — putting the answers at your fingertips when you need them most.

Topics Covered

• Pediatric thyroid function: interpreting TSH, fT4, fT3, rT3, and when values should trigger follow-up

• Presentation of Hashimoto’s thyroiditis and hypothyroidism in children and adolescents

• CBC interpretation in pediatrics: anemia patterns, transient erythroblastopenia, platelet abnormalities, and red flags for malignancy

• Iron studies: ferritin thresholds, when to order additional testing, and subtle signs of deficiency

• Vitamin D: appropriate testing, cutoffs, and interpretation in children

• Nutrient markers: zinc, folate, B12, riboflavin, thiamine, magnesium, and more — including functional vs. direct markers

• CMP findings: elevated alkaline phosphatase, A/G ratio, BUN/creatinine ratio, and their meaning in pediatrics

• Glucose and metabolic markers: lab patterns in diabetes, DKA, and reactive hypoglycemia

• Cholesterol and lipids in children, especially in the context of psychiatric or behavioral concerns

• Lead toxicity: Recognizing clinical signs, key laboratory findings, and the most accurate tests to order for diagnosis and follow-up.

• Clinical presentations: structured lab work-up for fatigue, picky eating, ADHD, lymphadenopathy, and growth failure

Course Includes

• 2-hour on-demand training

• 95+ page Pediatric Lab Interpretation Guide (fully searchable by test and age)

• Nutritional deficiency framework — signs, symptoms, when to test, and which labs are best

• Lab ordering templates for common pediatric presentations

• Over 50 clinical references and 20 links to research summaries and consensus guidelines

• 2.0 hours of CE credit for naturopathic physicians (AANP accredited)*

CE Accreditation

This course is approved for 2.0 hours of General Education CE credit for naturopathic physicians by the American Association of Naturopathic Physicians (AANP).

* Disclaimer for Oregon licensees:
The AANP is recognized by all regulated jurisdictions as an approver of continuing education for naturopathic doctors who graduate from CNME-accredited programs, except for Oregon. For all jurisdictions except Oregon, these activities meet Washington State’s Category 1 CE designation.

For Oregon licensees: Naturopathic Pediatrics PRO will provide the necessary documentation for you to submit an individual application to the OBNM for CE approval. Please contact OBNM prior to purchase for submission requirements.

➡️ Note: While CE credit is currently limited to naturopathic physicians, this course is open to all healthcare providers. The content is highly relevant for any clinician who orders or interprets pediatric labs.

Who Should Enroll

This course is designed for licensed healthcare providers and advanced clinical students who interpret pediatric labs as part of patient care — including naturopathic physicians, pediatricians, family physicians, nurse practitioners, physician assistants, and functional/integrative providers.
