N ote : The reference values provided in these tables should be used as guidelines only. Thus, any given result should be interpreted based on the reference value of the laboratory in which the test was done; the laboratory typically provides these values with the test result. See table Normal Laboratory Values: Urine. See table Normal Laboratory Values: Stool.

Blood Tests: Normal Values

The results of the test will show if a person is within the normal lab values. According to the Food and Drug Administration FDA , normal lab test values are a set of upper and lower limits generally given as a range since normal values vary from person to person. Laboratory tests are commonly administered in discovering the cause of symptoms, confirming a diagnosis and screening for diseases. The information obtained from the test can also help rule out, asses and monitor the progression of a disease and plan for treatment.

Reference Ranges

Readers should also be able to describe the general principles for selecting the most appropriate laboratory test based on its diagnostic performance characteristics. Chemistry questions and corresponding answer form are located after this CE Update article on page Frank H.

Reference values vary based on several factors, including the specific laboratory that supplies them. A patient's blood test values should be interpreted based on the reference value of the laboratory in which the test was done; the laboratory typically provides these values with the test result. These values are listed in alphabetical order in the following table. Antidiuretic hormone ADH; arginine vasopressin. A-I, females.


This table lists reference ranges (expressed in both SI units and traditional units) for the most common laboratory tests and is intended for interpretation of.


Clinical laboratory test results are a very important parameter in diagnosis, monitoring and screening. Thus a lot of data are provided and it is therefore imperative for patient care and safety that the clinicians are familiar with the tests and with interpretation of the results. The laboratory result must be interpreted on the background of a reference interval that is used to distinguish between "health" and "disease".

Normal Laboratory Values

Knowing the different normal lab values is an important step in making an informed clinical decision as a nurse. Diagnostic and laboratory tests are tools that provide invaluable insights and information about the patient. NCLEX will not give you values that are within normal range.
