Normal Laboratory Values for Examinations - Reference

Oct 14, 2026

Upload by aboduw

Normal Laboratory Values for Examinations provides reference ranges used in hematology, clinical chemistry, and arterial blood gas testing. It lists both metric (SI) values and traditional ranges for key analytes including hemoglobin, hematocrit, platelets, white blood cells, liver enzymes (ALT/AST), bilirubin, creatinine, electrolytes, coagulation markers (PT/INR, PTT), D-dimer, troponin I, and ESR. It also includes blood gas parameters such as pH, pCO2, pO2, bicarbonate, and O2 saturation, updated 11/2021, for general reference only.
