About this app
A study reference for laboratory values, medical abbreviations, and the word roots medical vocabulary is built from — for nursing and medical students, and for anyone reviewing the material. It works fully offline, with no account and no sign-up. WHAT YOU GET • Hundreds of lab reference values across 16 categories, in SI or US units — switch with one tap • Critical values, descriptions, and the differentials taught for high and low results • Common Panels: CBC, BMP, CMP, LFTs, ABG, coagulation, thyroid, iron studies, lipids, urinalysis, CSF, and hepatitis • Blood collection tube guide covering order of draw, additives, and inversion counts • Thousands of medical abbreviations, searchable instantly • 400+ medical prefixes and suffixes with origin, meaning, and examples • Powerful search with scopes for labs, abbreviations, panels, and tubes • Favorites, Recently Viewed, and an A–Z master list • Related labs and curated reference links (ClinLab Navigator, Lab Tests Online, MedlinePlus, Wikipedia, and more) on every lab MAKE IT YOURS • Every entry is editable — set ranges to match what your program or laboratory teaches • Add your own labs, abbreviations, and prefixes • Revert any edit back to the built-in reference with one tap • Your edits and favorites stay on your device and are never overwritten ALWAYS CURRENT Reference data updates automatically in the background, so corrections reach you without waiting for an app update. DESIGNED FOR 2026 A ground-up redesign with full dark mode, a dedicated iPad sidebar layout, and modern iOS design throughout. Updating from an earlier version? Your favorites, edits, and recents migrate automatically. PRIVATE BY DESIGN No account. No tracking. Anonymous usage statistics only — the text you type in search is never recorded, and nothing can be linked to you or your device. Lab Values+ is a study and teaching tool. It is not a medical device and is not for diagnosing or treating anyone. Nothing in it substitutes for clinical judgment, supervision, or your institution's guidelines. Reference ranges vary between laboratories — always confirm against the laboratory that ran the test.
Latest release
What’s New
FAVORITES ARE BACK ON THEIR OWN TAB A proper list of everything you've starred — labs, abbreviations and prefixes together — instead of a strip on the home screen. Swipe to remove. A SIMPLER HOME SCREEN Four tabs instead of five, and less stacked on the first screen. Abbreviations, Prefix/Suffix and the Tube Guide now live under More, and everything is still searchable from the Labs tab. Search also puts the test you actually typed at the top of the results, instead of anything that merely mentions it. BROWSING • An A–Z index down the side of All Labs, Abbreviations and Prefix/Suffix — jump straight to a letter instead of scrolling • Suffixes are filed under their own letter at last, so "-emia" sits under E rather than in a single pile • Tighter rows: about half again as many entries on screen • The blood tube guide now numbers each tube in the draw order REFERENCE DATA • Corrected units for PSA, globulin and total protein • Triglycerides consolidated into one risk-based entry • Lactate consolidated into "Lactic Acid" All reviewed by a physician.
