LabVals is a study reference for nursing and allied health students learning laboratory values: 117 test pages with adult ranges in conventional and SI units, a unit converter, flashcards, quizzes and 4 longer guides.
Where the ranges come from
The ranges are teaching values, the conventional adult bands students are examined on, rounded for study. Each test page prints its source line, which reads: “Adult reference values compiled from Pagana & Pagana, Mosby's Diagnostic and Laboratory Test Reference, and Fischbach & Dunning, A Manual of Laboratory and Diagnostic Tests.” Where that material gives a separate band by sex, age or pregnancy, the page shows it separately rather than averaging.
What it cannot tell you
It cannot interpret your own result. A reference interval belongs to the analyzer, the assay and the population a particular laboratory sampled, so two accredited laboratories can print different bands for the same test and both be right; the band beside your result is the one that applies to it. Why reference ranges differ goes through the reasons. A value outside a range here does not mean something is wrong with you, and one inside it does not mean all is well. The critical values are the thresholds taught for exams; the ones that trigger a callout are set by each facility's own policy. Nothing here is medical advice. Questions about a result belong with the clinician who ordered it.
Who runs it
One independent developer builds and maintains LabVals and a few other study sites: DoseDrill, AnatoMemory, PetriKey and TermDecode. Guides are published under the LabVals name with no personal byline, and the structured data gives the LabVals organization as their author. No clinical qualification is claimed. The date on a guide marks the last change to its text.
