What factors can affect my results?

Certain factors can impact the accuracy of lab test results, including:

* Foods and drinks: Consuming specific foods or beverages before the test
* Medications: Taking certain medications can alter results
* Stress: High stress levels can affect some tests
* Vigorous exercise: Intense exercise may influence specific tests
* Laboratory procedures: Variations in testing methods can yield different results
* Illness: Underlying medical conditions can impact test outcomes

Talk to your healthcare provider:

If you have any questions or concerns about your lab results, do not hesitate to discuss them with your healthcare professional.

False-positive and false-negative results:

* False-positive result: Indicates a positive test result for a disease or condition when it is not present.
* False-negative result: Indicates a negative test result when a disease or condition is actually present.

Incorrect results occur infrequently but are more likely with certain tests or improper testing procedures. Your provider may perform multiple tests to ensure an accurate diagnosis despite the rarity of these errors.

Measurement units and reference ranges:

* Measurement units: Different laboratories may use varying units of measurement for test results.
* Reference ranges: Reference ranges can vary based on geographical location and laboratory methodology.

Your results will be interpreted within the reference ranges provided by the laboratory. You can adjust measurement units and reference ranges in our Medical Tests Analyzer interface.

For example, a provider may record your weight in pounds or kilograms, and laboratories may use different measurement units for the same tests. Reference ranges for what is considered normal also vary across regions.
