What stays free?
The entire test reference — every "normal range for…" page and search — all panel pages, the SI ↔ conventional unit converter, and a fresh 10-question daily quiz round plus the first flashcard deck are free forever, no account needed.
What does Premium add?
Unlimited quiz practice across the whole question bank in any mode, every flashcard deck (not just the first), mastery tracking, printable per-panel cheat sheets, and personal notes on any test. It's the study depth for exam season.
Is this a source I can use for patient care?
No. LabVals is an educational study reference with standard teaching values. Reference ranges vary by lab and method — always use the range printed on the actual result and your facility's policy. Never make a clinical decision from these values.
