How To Read Laboratory Results?

In order to interpret a laboratory result, it must relate to a reference value. It can be the same patient’s earlier results, if possible, or it can be done by comparing data from a “normal” population to the patient’s earlier results.

What Is The Normal Range For Blood Test Results?


Normal range

red blood cells

men: 4.32–5.72 million cells/mcL; women: 3.90–5.03 million cells/mcL

white blood cells

3,500 to 10,500 cells/mcL


150,000 to 450,000/mcL


men: 13.5–17.5 grams/deciliter (g/dL); women: 12.0–15.5 g/dL

  • The normal white blood cell count is 3.5 to 10.5 billion cells per litre.
  • platelets count: 150-450 billion/L on average.
  • The normal blood sugar level for hemoglobin is 12.0-17.5 grams per day.
  • What Does Reference Range Mean On Lab Results?

    Reference ranges are sets of values that are used to calculate lab tests based on a group of otherwise healthy people who are tested. In between those limits, the values may vary depending on factors such as age, sex, and specimen type (blood, urine, spinal fluid, etc.).

    What Are Normal Lab Levels?


    Mean corpuscular hemoglobin concentration

    33-37 g/dL (330-370 g/L)

    Mean corpuscular volume

    80-96 µm3 (80-96 fL)

    Partial thromboplastin time (activated)

    20-35 sec

    Platelet count, blood

    150,000-350,000/mm3 (150-350 × 109/L)

    What Are Lab Values?

    Blood, urine, and body tissue samples are checked in laboratories to see if they match the normal range of values. A lab test is used to determine a patient’s overall health and well-being.

    What Do Lab Values Mean?

    A lab test is used to determine a patient’s overall health and well-being. The results of a patient’s lab test can be affected by many factors, but some of the most common are gender, age, race, medicines taken, and the presense of any underlying condition.

    Can A Nurse Interpret Lab Results?

    In many cases, nurses do not recognize lab tests as important because they believe that the doctor is responsible for interpreting them. In fact, this is not entirely accurate. In order to recognize trends that affect patients and develop a good nursing care plan, a nurse must also be familiar with lab tests.
