Blood Reference Levels
SORT by a column: click header. SEARCH for a term: type "Ctrl-F".
Component column has links to Wikipedia (collaborative encyclopedia), MedLinePlus (medical encyclopedia for consumers, from NIH), and PubMed (journal publications, compiled by NIH). Reference Ranges are from Harrison's Manual of Medicine (17th ed). Analyte column indicates whole blood, plasma (cells removed), or serum (cells and clotting factors removed).
