Not out yet — but it’s close.

What are the normal lab values — and the critical values — across the eight standard panels: CBC, BMP, additional chemistry, liver and protein (CMP), coagulation, ABG, lipid and urinalysis?

  • 54 tests across eight panels, each panel and test marked with its real specimen tube in its real cap colour
  • Sex-specific tests — hemoglobin, hematocrit, creatinine, HDL — carry a Female/Male toggle that shows at the flag
  • Search resolves abbreviations (BUN, Na), aliases (kalium, bad cholesterol), British spellings and typos, and mirrors the query back; where a test is not covered the app names its own boundary rather than giving a dead end
  • A Critical values tab for the labs you call about, and an additive acid–base interpreter that names the pattern of pH, PaCO₂ and HCO₃⁻ and nothing beyond it

What it is

Lab values, normal and critical, on one ruler. 54 laboratory tests across the eight standard panels — CBC, metabolic panel, additional chemistry, liver and protein, coagulation, arterial blood gas, lipids and urinalysis — each carrying its normal reference range, its critical value where one applies, the specimen, a plain-language note on what it means, and its own named source. Type a result and it plots on the very same ruler its reference range is printed on, flagged low, normal, high or critical by its position rather than by a claimed colour.

Why we built it

A reference that colours a number and a table that prints a range are two things that can drift apart. Here they are one drawing: the flag a value gets is its geometric position on the bracket, the critical thresholds are ringed on that same axis, and the flag reads with no colour at all — a margin letter (LL, L, OK, H, HH), a shape, a word and a place on the bracket — so it is safe for colour-blind readers. It is an educational reference, not medical advice and not a diagnostic tool: ranges and critical values vary by laboratory, method, age and population, so always use your facility's own.

Lab Values is one of 27. We can build yours.

Every app on the shelf started as one honest problem, scoped small and built native, end to end. That’s exactly how we approach client work — designed, built and shipped, without the bloat.
