Understanding Your Lab Test Results

If your test results fall outside the reference range, it does not necessarily indicate a health issue. Reference ranges help determine if results are within the normal interval, elevated, or reduced.

Factors Affecting Test Results:

* Individual's health history
* Lifestyle and hobbies
* Age, sex, and ethnicity
* Different laboratory testing methods

Reference Ranges:

* Reference ranges vary from laboratory to laboratory.
* They are printed alongside test results on laboratory reports.

Interpreting Test Results:

* Each test has a specific purpose.
* Consider the variation in methodologies used by different laboratories.
* Historically, patients have relied on their doctors to interpret results.

Risks of Blood Tests:

Phlebotomy (blood drawing) is generally safe, but potential risks include:

* Bleeding and Bruising: Pressure applied after needle removal minimizes this risk.
* Pain: Usually minor and temporary.
* Swollen or Edematous Arm: Avoid taking blood samples from these areas.
* Dizziness: Inform the person drawing blood immediately if you feel dizzy.
* Infection: Rare but possible.
