Review common adult laboratory reference intervals and units.
This free tool stays open whenever you need it. When you want to build exam confidence, continue with full NurseNest practice questions and rationales.
Explore study plansThey include CBC, electrolytes, renal and liver markers, cardiac markers, coagulation studies, glucose, and ABG values, each with typical reference ranges used in nursing school.
Yes. Ranges vary by laboratory method, age, pregnancy status, clinical context, and country, so always check your institution's printed ranges.
Look at the trend, the clinical context, symptoms, and associated risks together, rather than treating a single number in isolation.
No. It is a study reference. Interpretation for real care must combine labs with assessment, orders, and provider judgement.
These answers are for nursing education and exam practice only and do not provide patient-specific medical advice.
This page is a quick reference table only. For full clinical lessons, NCLEX-style questions, flashcards, and practice-test integration, use the Labs hub in your study area.
