Quick reference for the labs nurses run every shift
Whether you're prepping for NCLEX, orienting on a new unit, or rounding on a complex patient, the lab panel matters. This hub collects the normal ranges, critical values, and nursing significance for the labs we draw most often — CBC, BMP, CMP, coags, ABGs, cardiac markers, and more.
Every page lists the nursing implications alongside the value: what the result means at the bedside, when to call the provider, and what to chart.
