What are laboratory 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.
What are the normal lab values for electrolytes?

What lab values should nurses know?
Identifying Laboratory Values
- Partial pressure of oxygen (PaO2): 75 – 100 mmHg.
- Partial pressure of carbon dioxide (PaCO2): 38 – 42 mmHg.
- Arterial blood pH: 7.38 – 7.42.
- Oxygen saturation (SaO2): 94 – 100%
- Bicarbonate – (HCO3): 22 – 28 mEq/L.
What are normal lab values for potassium?
Normally, your blood potassium level is 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L ) can be life-threatening and requires urgent medical attention.
What is a normal WBC level?
The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens. Talk to your provider about your test results.
What does value mean in lab results?
Reference values are the values expected for a healthy person. They are sometimes called “normal” values. By comparing your test results with reference values, you and your healthcare provider can see if any of your test results fall outside the range of expected values.
Why are lab values important?
Lab values are used to determine a patient’s overall health and well-being. There are many factors that can affect a patient’s result and lab values but some of the most common factors are gender, age, race, the medicines taken, and the presence of any underlying condition(s).
What lab values does NCLEX use?
Metabolic Panel Lab Values NCLEX® Review

How do you memorize medical lab values?
Use the letters “od” in sodium to remember “odd” numbers. Then combine the first 3 odd numbers which are 1, 3, and 5. This will give you 135 which is the lower end of normal. Simply add 10, and this will give you the normal range of 135-145 mEq/L.
