Grayson Nursing Laboratory Values: Normal Ranges for Various Clinical Tests, Lecture notes of Nursing

Central Louisiana Technical Community College (CLTCC) - North Central CampusNursing

The normal ranges for various clinical tests including common lab tests, cardiac markers, lipid panel, urine analysis, 24 hour urine, coagulation, cerebral spinal fluid, hemodynamic parameters, and arterial blood gas values. It also includes medication levels.

What you will learn

  • What are the normal ranges for cardiac markers such as troponin, myoglobin, and CPK-MB?
  • What are the normal ranges for urine analysis parameters such as specific gravity, pH, and protein?
  • What are the normal ranges for common lab tests such as ADH, albumin, alkaline phosphatase, and ammonia?
