Pediatric Lab Reference Values

Normal Values — Pediatric & Neonatal

1 What is the Pediatric Lab Reference Values?

Pediatric Lab Reference Values is a searchable, browsable reference tool inside PediAid for looking up normal laboratory values relevant to pediatric and neonatal patients. Labs and reference guides are organized by clinical system — including cardiology, endocrinology, fluids & electrolytes, gastroenterology, genetics, hematology, immunology & allergy, microbiology & infectious disease, neonatology, nephrology, nutrition & growth, oncology, poisonings, pulmonology, rheumatology, and trauma & critical care — and users can either browse by system or search directly for a specific lab test or guide. The reference is drawn from the Harriet Lane Handbook, 22nd Edition.

2 When to use it

  • Quickly looking up a normal pediatric lab value at the bedside or during rounds
  • Comparing a patient's result against age-appropriate pediatric reference ranges rather than adult norms
  • Browsing labs organized by organ system or specialty, such as hematology, nephrology, or endocrinology
  • Searching for a specific test or reference guide by name across all systems
  • Cross-checking values across systems such as fluids & electrolytes, nutrition & growth, and poisonings

3 Formula & method

This is a reference and search tool rather than a calculator. Lab items and guides are grouped into clinical systems, shown as tiles with a count of how many items in that system currently have data; tapping a system opens its list of items, or the search bar can be used to find a specific lab or guide by name across all systems.

4 Frequently asked questions

What is the source for the pediatric lab reference values?

The tool's own reference footer cites the Harriet Lane Handbook, 22nd Edition.

How are labs organized in this tool?

By clinical system — such as cardiology, hematology, nephrology, neonatology, and endocrinology — which can be browsed as tiles, or searched directly by name.

Can I search for a specific lab test directly?

Yes, the tool includes a search bar for finding labs and guides by name instead of browsing by system.

Does this tool calculate anything, or is it purely a reference?

It is purely a reference and lookup tool — it does not perform any calculations.

Are all listed lab items populated with data?

Not necessarily — the tool marks some items as "Coming Soon" when data has not yet been added for that item, and shows a data-availability count on each system tile.
