Common Lab Tests

Why an abnormal result doesn't always mean something is wrong

Understanding abnormal results on common blood tests can be a source of concern for many patients. However, it's important to recognize that not all abnormalities indicate a serious health issue. Here are several reasons why abnormal results on blood tests may not be of immediate concern:

  • Normal Ranges: Normal ranges for blood tests are established based on the average values found in a healthy population. Just as there is a range of heights considered normal in a population, there is also a range of values for various blood parameters. Being outside this range doesn't necessarily signify disease.
  • Individual Variation: Like height, our bodies exhibit natural variation in blood parameters from person to person. What's normal for one individual may be slightly different for another. Therefore, a result slightly outside the normal range may still be perfectly normal for that person.
  • Lab Variability: Even the most reputable labs may have slight variations in their testing methods and equipment. This can lead to small differences in reported values. As a result, what may appear as an abnormal result in one lab could fall within the normal range in another.
  • Biological Fluctuations: Our bodies are dynamic, and various factors such as diet, hydration, stress, and time of day can influence blood test results. For instance, sugar levels can vary depending on recent meals. Testosterone levels vary dramatically depending on time of day. Therefore, a single abnormal result may not accurately reflect a person's overall health status.
  • Temporary Conditions: Certain factors, such as recent illness or injury, can temporarily affect blood test results. For example, an elevated white blood cell count may be indicative of an infection that the body is fighting off but stress or pregnancy as well as a number of other non-infectious conditions can also cause it to go up.
  • Age and Gender Differences: Normal ranges for blood parameters may vary based on factors such as age, gender, and even ethnicity. What's considered normal for a teenager may differ from what's normal for an older adult.
  • Medications and Supplements: Some medications and supplements can influence blood test results. It's essential to inform your healthcare provider about any medications or supplements you're taking to ensure accurate interpretation of your results.

Interpreting test results requires more than reading the numbers. It requires a comprehensive analysis of the whole patient. An elevated white blood count (WBC) could be serious in a 30 year old woman with a fever but it can be completely normal in a healthy 30 year old pregnant woman because pregnancy normally causes a rise in the WBC.  Anemia in the form of a low Hgb (Hemoglobin) can be completely normal in a young woman who is still having her periods but in an older woman or in any man it can be a concerning sign that they have a gastrointestinal bleed and possibly even cancer.

In summary, just as being taller or shorter than average doesn't necessarily indicate a health problem, being outside the normal range on a blood test doesn't always mean there's a disease present. It's crucial to consider individual factors, lab variability, and temporary conditions when interpreting blood test results.  Remember, knowledge is power but it can also be confusing. Understanding your blood test results empowers you to take control of your health but only if you can put those results in proper context. and understand when they require action and when they are OK.

If you have concerns about your results, it's always best to consult with a healthcare professional who can provide personalized guidance based on your unique situation.
